Like most Linux distributions (or mobile device operating systems like say Android or iOS), the functionality of the system can be upgraded rather significantly by downloading and installing pre-made packages from package repositories (local or on the Internet). I'm a noob, Followed this guide (instructions is also written in plan text under the video): Definitely, not much time but… for sure, higher than zero hours per week , Feel free to drop me an e-mail: [at] it. than everything sounds very easy. Let’s check: The first is the one we required. Bingo!… it worked! When I follow the guide on pistaches webpage to prepare the package I get no tar.gz. Tried to install wireguard and some QoS-software but both of them get this "wrong kernel-error". The final file structure for our own repo should be like this: A “build” purposely built for your cross-compilation requirements. Why? I’ve been able to build helloworld example as a package by following the official documentation but the Lidar source is MUCH more complicated and beyond my ability. ….let’s issue a “make” (actually, as I have an 8-core CPU, I’m going to launch a make -j8 ) and take the chance of a small walk, as the building process will require some time. Its functionality and purpose are comparable to apt on Debian-based systems. Then I found some ways to install and use packages from localhost i.e. My dl/ archive has libtirpc_1.2.5-1_mips_24kc.ipk downloaded on Mar 2 18:30 and the packages download site currently has libtirpc_1.2.5-1_mips_24kc.ipk built … file. Since this is an OpenWrt upgrade, I’m going to assume that ssh is enabled. As I already stated above, the official documentation is quite oversimplied as the “Makefile” it provide is for the “simple” helloworld.c file and… as you know, now, our “pmacct” is quite a different beast. I would like to write a package that utilizes Modbus TCP to read registers from a modbus device connected via ethernet and send the data to Azure IoT Hub. Here is a picture: Also firmware upgrades quickly cease. So to step further we need to tell the SDK what to do (eg. hard drive on a pc, connected via LAN, but this seems useless if the PC is turned off. Having said that, let me add that I’m surely interested in any kind of software development, provided that it will be conducted under the Open Source umbrella. It may seem stupid but it’s worth mentioning if anyone has the same problem. Then let’s confirm “.config” as the filename to save, and then simply exit until getting back to prompt. At the very bottom you’ll find the commands, if someone likes to work. What to do? In your opinion and experience, can it work? If you want, you can cut-and-paste here related output so that, eventually, I can step further! It took, to me, around 10 hours of hard work to really “catch” such an ordered list . /openwrt/openwrt-sdk-18.06.4-ramips-mt76x8_gcc-7.3.0_musl.Linux-x86_64/staging_dir/toolchain-mipsel_24kc_gcc-7.3.0_musl/bin/mipsel-openwrt-linux-gcc: line 5: /openwrt/openwrt-sdk-18.06.4-ramips-mt76x8_gcc-7.3.0_musl.Linux-x86_64/staging_dir/toolchain-mipsel_24kc_gcc-7.3.0_musl/bin/../../host/lib/ cannot execute binary file: Exec format error Following Makefile HAS NOTHING TO DO with the Makefile included in the pmacct sources. Hi Brian. The next snapshot created will invalidate the current packages, so you either have to install You can check the official package, here: Think I didn't have the latest snapshot after all. You can see the package dependencies for wireguard at In order to get the whole picture, some preliminary issues need to be fixed/clarified. This, ’cause normally the SDK rely on the “feeds.conf.default” file. I noticed that a few of my packages have exactly the same installed time, so busybox would be the only package excluded from the output list. when you get “comfortable” with it… when you have already and successfully used it a couple of times…. Make menuconfig will bring a GUI to select various parameters before initiating the build process such as – Target build system & subsystem; Packages required to be part of the build – Base packages, packages required for system administration, development packages & extra packages. But I guess that if you’re reading these notes, chances are high that it’s your “first time”, so you –like me– are struggling a bit. Exactly what we need to… copy! I made the same test on a 64bit linux machine and it worked fine. (…and, please,  leave comments below!). And so…. Copy the Packages file to the router: $ scp Packages root@ Anyway I’d start checking two things: 1) that your executable is really an executable built for the Armada385/ARM platform; 2) that you build a “static” binary, so that it (the binary) do **NOT** require additional files (aka: dynamic libraries). Let me add that I also had some “contact” with ModBus (and ModBus/TCP) also regarding Arduino and other “smaller” (with respect to OpenWRT) environment. As pmacct has plenty of “configure” options, due to typical OpenWRT constraint (low resources) I disabled lots of unneeded options. In February 2019 this feed was created by moving these packages out of the OpenWrt "luci"-feed. After connecting of the usb-hub you can use its capabilities. Indeed, when you know about SDK…. I build my images with image builder in a "slow" VM. opkg retrieves the lists of package available for installation from over an unencrypted HTTP connection. System –> Software. For example, I want to install wireguard - then I download everything that may be needed. I already knew that building a software to run on my WDR4300 were going to be not an easy task. Anyone that can tell me something about this? Maybe You can help me now. I think installed time is not the flash time, but the install time during the build process of the image. The transmission-web package and it's dependencies will consume around 1.2 MB of free space, make sure you have enough free space left on the router, or setup extroot . So…. If you are not going to modify the packages themselves, just create an image with a specific list of packages, you can use the image builder instead: Using the Image Builder The Image Builder (previously called the Image Generator) is a pre-compiled environment suitable for creating custom images without the need for compiling them from source. Switch to Available packages tab to show and install available packages. in "make menusetup", saved, and then "make -j5" - with no luck. make: *** No rule to make target ‘mipsel/sha1.o’, needed by ‘link’. Keep this in mind! My aim is to be able to program my own software and build it in as a package into OpenWrt. ); Lines 16+15 and 11+12: they are used to calculate the URL where the SDK will DOWNLOAD the source file (in this case, a “.tar.gz”). I’m struggling to even get helloworld to work on mine. If you forget this… the build process will NOT start and… it’s not immediately clear why it’s failing; Lines 21: this is the folder where the SDK will uncompress the TGZ and start the real build. The opkg utility (an ipkg fork) is a lightweight package manager used to download and install OpenWrt packages from local package repositories or ones located on the Internet. and a URL. everything you think you need at once, or make a local backup of the whole package repository. Returns you to the router menu on your IP and logs you in. Obviously, it’s close to impossible to build the whole PMACCT on such a device (I mean: having a GCC compiler and all the related tool in such a small device… is definitely challenging!). I’ve been able to ‘make’ and run the lidar examples in my linux box so i know the source files work, but I have no idea how to reconfigure the ‘feeds’ Makefile to compile the lidar code. Openwrt on a Pc. As for your own repo, are you referring to the “feeds.conf” file I described in paragraph 4.1? It’s amazing that, once connected via SSH, you simply launch an opkg install tcpdump and in a few seconds you get the “tcpdump” package downloaded and installed on your box. Navigate to LuCI → System → Software. In my case, as “pmacct” requires both “libpcap” and “libpthread”, which are included inside the “packages” feed, in decided to define a “feeds.conf” file containing my brand-new repository as well as the “base” and “packages” one. let the SDK to be able to “select” the building of the tcpdump tool. Ok. Let’s start again by writing down our problem: Now, in this stage, you have all the required SDK components in place. Result should be under the […]/bin/packages folder tree. It’s amazing that, once connected via SSH, you simply launch an opkg install tcpdump and in a few seconds you get the “tcpdump” package downloaded and installed on your box. How? Login as … So long, that we don’t want to wait! This is exactly where the Official OpenWRT SDK come to help, as it’s described with: “The SDK is a pre-compiled toolchain designed to cross compile packages for a specific target“. For various reasons, last week I decided to run on it a software (pmacct, indeed) that was NOT included in the official package repository. So we need it as well. All I require is the simple_grabber app really. As for 1), it should be enough to launch an “file ”. Actually, a “Makefile” specifiying how to deal with such a package., If you would like to skip the whole thing, download the premade snapshot, and install the Click on Update lists and wait just a second, then continue below: german as a search term to enter, and to Find this package , click. I am looking for a simple walkthrough to redirect all port 53 traffic from any IP besides (hi-hole) to it. Let’s tell the SDK that we want to build it, by pressing the “M” key (“M” stand for “Module”) on “tcpdump”. Let’s start trying to rebuild an existing package. I do not want to reinvent the wheel. In order to define our own “package repository” (our own “openwrt feed”) we simply create an empty folder on our local Linux box and define such a folder at the top of the […]/feeds.conf file. OpenWrt OpenVPN Setup Guide This guide was produced using OpenWrt v.18.06.2 Open the terminal on your computer and log in to your router via the SSH: # ssh root@ The router’s username and IP address above are default. Right now I was packaging a autoconf-based source, and I was missing the PKG_FIXUP:=autoreconf. Using ipkg to install OpenWRT packages. Let’s experiment with the tcpdump package. Hopefully. With things changing so fast, that seems like a boon only for the router manufacturers. But I do not understand how to package this. Unfortunately it’s not easy to “guess” the exact problem you’re facing. The current version of the firmware can be determined using: You can use this information when choosing the correct sysupgrade binary and also for validating that the upgrade was successful. Connect the USB stick and copy the file system to it in order not to be dependent on the size of flash memory in the router. Choose how you want to connect to OVPN 2. Is there a way to download a complete "a whole set" of packages for a application I want to be included when I make my install? The optimal way to solve this problem is really simple: define a new “feed” inside of which we’re going to put our new “pmacct” package. Read here for possible solutions. Creating the mail folder and related “pmacct” folder was really easy, obviously: The REALLY BIG PROBLEM was figuring out HOW TO CREATE THE MAKEFILE for my PMACCT package. Better: it can be used but only in the way we used it here above; to compile stand-alone “.c” application, without any chances to deal with openwrt packages or complex autoconf projects. 4) install packages as you do normally with: opkg update; opkg install foobar (Last edited by written_direcon on 1 Nov 2011, 22:55) Log on the router, cd /tmp and install the local package: root@OpenWrt:~# opkg install mypackage_brcm63xx.ipk. Once the SDK has been downloaded and unzipped, “feeds” need to be checked-in with a ./scripts/feeds update -a command: Right after feeds-update, SDK is STILL useless. Probably a simple thing but beyond my intuition. Hi UB, thanks for commenting and for appreciating my writing , I’d be pleased to help you furthermore. Your email address will not be published. 3.1. My WDR4300 is powered by a MIPS-based CPU: So, I needed to build an executable to run on a “MIPS 74Kc V4.12” CPU. I compiled the helloworld.arm successfully on my Linux box (the x86 version worked fine), but when I run it on my router, it says: I checked the file is there and that is has the execute bit… Any ideas on what I’m doing wrong? I am just starting out with OpenWrt using an RUT230 from Teltonika and this has been a very great eye opener. I know you may not have enough time, but I would really like to connect to you and see if we can put our heads together in this (If you allow me.). As you can see in line 3, the compiler properly built the x86-64 version, that actually succesfully run on my Linux box (lines 5 and 6). Such a behaviour is definitely possibile: I’m also sure that you know as well, that just before start working with the opkg package manager, you need to UPDATE the list of available packages. “download” the sources from a proper repository and put them somewhere inside the SDK folder structure; “download” some additional files (among of which, unfortunately, a file named Makefile…that is a really different thing with respect to the Makefiles included in the tcpdump sources, related to the autoconf cicle); “download” every required packages (tcpdump requires libpcap, so the libpcap packages is “installed” as well). This is the OpenWrt "packages"-feed containing community-maintained build scripts, options and patches for applications, modules and libraries used within OpenWrt. I’m sure you already guessed one of such actions: updating the feeds, so that the SDK for itself will know WHERE to download packages sources, should it need some of then during the rebuilding and/or compiling activities. This is exactly the results of the “feeds install” command that we issued before. And simple, actually. you need jffs or samba fs to install your packages into telnet/ssh in and type mkdir /jffs/tmp mkdir /jffs/tmp/ipkg /tmp # … Obviously I double-checked that the calculated URL is working properly; Lines 17: this is the SHA256 checksum of the downloaded “.tgz”. The OpenWRT page does come with a warning about upgrading all packages, but also provides details on how to do it: did you use this to download the snapshot? But in this stage… it’s useless simply ’cause it has nothing to do! Installing OpenWrt via TFTP Although you can install the firmware through more traditional means (via webpage), there are reasons to install via TFTP . ELF 32-bit MSB shared object, MIPS, MIPS32 rel2. This may not be a critical issue for you since it is a LAN facing service, but the type of infrastructure information being exchanged combined with the fact that it is usually accessed over WiFi protocols might make you want to consider it – especially considering it is a 5 minute fix. It’s also possible to host the “.tar.gz” locally, but I found easier (and better) to rely on the “real” official source. I’m quite sure that something around ModBus/TCP have already been built for OpenWRT but… unfortunately I don’t have details. We are using openwrt 18.06.01, the benefit is it can directly download openwrt compiled packages from openwrt official website. Thanks. Than “SAVE”. I am able to build the library with the toolchain and cmake(-gui), I get no errors. That's what i did and worked fine. Think there is a git-command, like "git upgrade" and then check status with "git status". OpenWrt (from open wireless router) is an open-source project for embedded operating systems based on Linux, primarily used on embedded devices to route network traffic. the whole process, above, CANNOT be applied. The pages are provided for historical reference only. If you created your own image, you "have to" use your own packages as well. I’m strugling with it but still can’t get it to work… Hi, So I have this TP-Link WR740N, on which I installed OpenWrt. Well…. But I try this by myself and have not the same results. It looks like in the Makefile you have a “target” defined like “mipsel” and, within such a definition, you have some “rules” to build sort of “sha1” library (and, hence, mipsel/sha1.o object file). 1) setup a local web server in your LAN (subnet) 2) put the package repository in there. Those two commands should be launched on your Linux-box. A freshly compiled pmacct_1.6.2-1_mips_24kc.ipk package!!!! Any ideas how I do to just update to latest version before I want to make a fresh install instead of deleting the whole openwrt-map and start all over again? “Makefile”. These two lines say exactly this , Lines 51-57: they say where the “pmacct” module can be “actived” inside the “make menuconfig” interface and, also, that pmacct require also libpcap and libpthread packages (as dependencies), Lines 60-64: they tell the SDK that the package it’s going to build should include the four binaries pmacct, pmacctd, sfacctd and nfacctd and that those binaries should be installed in the /usr/sbin folder. Don’t you? android apache C code cpanel decode desire disk encode extension extract fix free game hosting htc introduction java linux matlab 7 mod_rewrite mysql number conversion opencv OpenWRT php pixel programming redirect router shell skype social media syntax highlighter ubuntu upgrade url url shortener utf-8 video virtualbox virtualization VPN windows 7 wordpress How do I install packages? you could download the packages from the internet to your PC , install a webserver , place the packages in the local webserver , edit the opkg.conf to point to your local webserver , okpg update and then run as usual. opkg update opkg install transmission-web. Actually, even the “libpcap” package has been built (remember? 3) change /etc/opkg.conf on the router to point to your local package repository. The OpenWRT Package Manager To install or update software on an OpenWRT system, a utility called opgk is used. and it refers to the whole folder (/usr/local/src/SOABIT_OWRT_REPO) and not to the Makefile. With your help (and not a lot else) I was able to compile existing packages and run the hello-world on my WR710n. Compiled the hello.c only. Any suggestions would be greatly appreciated. Enjoy! Also, as a final note, for sure I’ll have to find some time, for such an activity, to be “cutted” from other tasks. Can we shout: “All done!”. I also tried to install the "package" (is that the name for it?) It downloads pre-compiled packages and integrates... Powered by Discourse, best viewed with JavaScript enabled, Latest snapshot - still problems with installing packages,,,, Here it is: As you can see, my own repository is going to be defined inside the SOABIT_OWRT_REPO folder. Well, you got the point: In my stock OpenWRT box, I found the following six pre-configured feeds: Every line (aka: every feed) specify a format (src/gz), an identifier (openwrt_core, openwrt_base, openwrt_luci, etc.) Install-Package uses the MinimumVersion and MaximumVersion parameters to specify a range of software versions. Before moving on, make sure opkg does not use any deprecated URL by tryin… What exactly should be better described? Packages from the tracker will usually have to be installed by using as a URI rather than a package name, unless you've updated your /etc/ipkg.conf file … SysAdmin, Networking, WebDev and Geek F/OSS IT stuff... opkg install /tmp/pmacct_1.6.2-1_mips_24kc.ipk. This is NOT a requirement, simply a damned good idea if you use self compiled firmware images; if anything goes wrong you can just TFTP the old firmware back. I installed latest snapshot (I suppose) today around 19.00, following this guide: Should you have trouble following this guide, please, leave a comment below: I’ll be proud to help you in an ad-hoc thread. If i do $file pistache/src/ it says: Frankly, I really don’t know how to help. It was easy to understand “the main figure” (aka: the SDK as a tool to build “packages” and/or “kernel-modules” WITHOUT requiring to build “the whole world”). Freifunk feed for OpenWrt Description. Let’s proceed…. brother can you compile * via commandline * See OPKG Examples to get you started * See OPKG for in-depth explanation * via GUI / LuCi * System -> Software -> Update lists * Filter for the device you are searching for * Click Available packages As you can see above, the first line of the “feeds.conf” is exactly referencing my own repository: `src-link soabitrepo /usr/local/src/SOABIT_OWRT_REPO`. Right after the download/unzip of the SDK, if you don’t perform other actions, basically the SDK is “useless”. opkg install /tmp/pmacct_1.6.2-1_mips_24kc.ipk This is a terrific tutorial for a complicated, error-prone subject. I’m NOT going to describe above file in detail…. After 3 minutes (in my case, remember, I used a parallel approach thanks to -j8) this came out: So… everything seems succesfully finished. As you might guess, PMACCT is built around much more than a single “.c” file. Anyway, here is what I think it’s important: Once the Makefile-manifest is ready, we simply: Now we fire the make menuconfig  tool and we should find “pmacct” under the Network menu: Now we simply press “M” to activate the PMACCT package and then “SAVE” the “.config” config file and Exit. and then, everything worked correctly: Now… it’s only a matter to properly configure the various tool but… this is definitily a topic for a completely different POST! Click Update lists button to fetch a list of available packages. Remember: we want to rebuild ONLY tcpdump! Is that correct? Because the PMACCT tool is available only as a “.tar.gz” and is NOT packaged inside some of the existing OpenWRT repositories. Here it is! Jump to: navigation, search. Back to “make menuconfig”, right after launching it, you get the main page: we start telling the SDK that we DON’T need to build all target/kernel/modules and, also, we DON’T need key-signing issues. In my case, I own a nice TP-Link WDR4300 that loooong time ago was “upgraded” to OpenWRT. to start discovering the “development” side of OpenWRT. So I promptly downloaded the SDK version provided for the WDR4300 platform (ar71xx/generic) and got ready to use it: To start experimenting with the SDK, as told by official instruction, I defined: In order to make some test, I decided to focus on the classic helloworld.c. So I simply created such a folder and… everything should be ready to start hosting my own “packages”. Very logic. When you get the message “Cannot satisfy the following dependencies for…” it is most likely because you installed a snapshot version of OpenWrt. In order to tell the SDK that we want to rebuild the tcpdump package, we simply issue a ./scripts/feeds install tcpdump . : The little network routers you can purchase in the store are ok, but they are not upgradeable. Ah, ok. Unfortunately my PC is running on a very common x86 platform. But still, I get mismatch-error when trying to install packages in LuCI. I’m sure you already know about “OpenWRT packages”. Ok. Thank you very much! this package for linksys wrt610n v2 ?? Example 3: Install packages by specifying a range of versions. To install package from local source file: install.packages(path_to_source, repos = NULL, type="source") install.packages("~/Downloads/", repos=NULL, type="source") Here, path_to_source is absolute path of local source file. As soon as I moved such a MIPS-binary to my WDR4300…. I finally was able to create the Makefile of my PMACCT package. By default, your router should have the IP address First, connect to LUCI (the interface on your router) by going through your browser. libpcap is a “dependency” for our pmacct). Once back to the prompt, we launch the building with a make and few minutes later, here is the result: As you can see, despite some minor warnings, everything has been built. we’ll find the tcpdump (and tcpdump-mini) options! Thanks for this great post. Such a scenario was exactly what I was waiting for…. $ mipsel-openwrt-linux-gcc -o hello.mipsel hello.c This sounds like a wrong (bugged?) Disclaimer: in order to keep this post as short as possible, I’m going to be slightly technical. Such a command will connect to several remote sites and download a “list” of packages than can be retrieved from such sites. So this line helped. it looks to me that the nft-qos is aready packaged in the official kernel, as reported in your link. hosts a list of Official Packages, as well as a Package Tracker and listing all known packages. It’s enlightening but it would be better with some more clarification where I struggled about . As soon as you will get back to prompt, you’ll see something similar to this: As you can see, just before the prompt we have a nice “End of the configuration” message, kindly informing us that we can proceed with “make”. $ make target=mipsel Guide to install OpenVPN for OpenWrt 1. And where do I place my packages before "doing a make" (compile?)? But in our case, “defaults” are not enough…. In order to keep things under control, multiple feeds have been created so to “group”/”classify” the various package repositories. Note dated April 1, 2020: OpenWRT users should Now install either version 18.06.7 or 19.07.1, both of which were released in February 2020. What is missing is “the package” that the SDK is expecting for the rebuilding activity. The second has been automatically built by the SDK as it’s a REQUIRED DEPENDENCY for tcpdump. Lines 30-34: before building pmacct for OpenWRT I tried building it for a “standard” Linux environment. The main components are Linux, util-linux, musl, and BusyBox.All components have been optimized to be small enough to fit into the limited storage and memory available in home routers. The packages you enable will be compiled, and their dependencies too, if I remember correctly. This cute portable router comes with an installation of OpenWRT, ... First I installed Python on the router using the OpenWRT package manager. Excellent post. Sorry. Due to this, you shoud be able to “recompile” it, by working directly on the “official OpenWRT distribution” and… *WITHOUT* the need to go through the lenghty, complex and error-prone process I’ve reported in my post.
