Updated - December 30, by Arnab Satapathi. First you need to determine your router platform, i. In OpenWrt this platform is called ar71xx. You're going to need a working 64 bit Linux distro to get the image builder working, most probably you are running one, and basic knowledge of using command line tools of course. Now install some software like GNU make and others, necessary for compiling linking and building the firmware. For Debian, Ubuntu or any other Debian based distro, install build-essential package, this will install the rest.
This step is important one, you've to find out which packages you want to add or remove, without compromising stability. Bellow the package list I want to remove.
Beginners guide to building your own firmware
You can safely remove all IPv6 related packages instead of LuCI to save some free space on the router. I also want to add few extra packages to get extroot working right after the flashing without installing anything extra. Here are these extra packages. Now build the openwrt minimal image, use the make info command to get available build profile and select a suitable profile.
The above command is very long, better to copy it to somewhere for analysis. Bellow the same command, but broken down into parts. Before flashing openwrt, check the size of the flashable bin file, the squashfs factory image is around 3.
Flash the new openwrt minimal build the way you like to do it, from the web interface or via sysupgrade command or whatever. Also don't forget to use an UPS to power up the router if you are facing frequent power cuts, as I have to, if power goes middle of the flashing, that will surely brick the router. So that's it how to build your own custom OpnWrt firmware, and hopefully this guide is easy to understand for everyone.
Also don't forget to share this if you thinks it's helpful. Hi Arnab Glad I came across this webpage.A case-sensitive filesystem is required. It is recommended that you use a Linux distribution for example Debianeither a standalone installation or one running in a virtual environment VirtualboxVMware or Qemu.
Ubuntu under Windows Subsystem for Linux is not an officially supported environment, but it appears to produce good builds.
It has been tested and I can confirm that it worked like a charm the first time, certainly better than full Linux system Ubuntu Cygwin Windows is NOT supported because the file system isn't case-sensitive. To generate a flashable firmware image file with default packages, you should have at least GB of free disk space better if more and at least 2 GB of RAM for the compilation stage.
The more additional packages you add in the image, the more space is required, but the space requirements should increase slowly, most of the storage requirements are for the build infrastructure and core components of the firmware image. Do note that these numbers are rough estimates only, you may very well be able to do it with less on some devices, but it's not guaranteed. Unfortunately not all dependencies are checked by make configespecially for packages. You may encounter compile errors because you need a specific library in your system, and the only way is to search the missing library from the compiler error log and see what package contains it in your own distro.
The following table is a partial list of such dependencies:. Do everything as normal user, don't use root user or sudo! Do not download sources in a directory that has spaces in its parent folders or full path! The development branch contains the latest additions to LEDE, may have experimental or unstable code.
Additional packages can be found in several feeds Luci, packages, routing, management etc. The build system will clone the correct feeds later when you update the package feeds. User Tools Register Log In.

Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application.
For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned. See the Table of Hardware for supported devices. It is the successor of the previous The OpenWrt The current stable version series of OpenWrt is It was released on 6 March People install OpenWrt because they believe it works better than the stock firmware from their vendor.
They find it is more stable, offers more features, is more secure and has better support. User Tools Register Log In. Site Tools Search.

Detailed Changelog. Browse Source. Extensibility: OpenWrt provides many capabilities found only in high-end devices. Security: OpenWrt's standard installation is secure by default, with Wi-Fi disabled, no poor passwords or backdoors. OpenWrt's software components are kept up-to-date, so vulnerabilities get closed shortly after they are discovered.
Performance and Stability: OpenWrt firmware is made of standardized modules used in all supported devices. This means each module will likely receive more testing and bug fixing than stock firmware which can be tweaked for each product line and never touched again. You can interact directly with developers, volunteers managing the software modules and with other long-time OpenWrt users, drastically increasing the chances you will solve the issue at hand.
Research: Many teams use OpenWrt as a platform for their research into network performance. This means that the improvements of their successful experiments will be available in OpenWrt first, well before it gets incorporated into mainline, vendor firmware.
It has been entirely created by a team of volunteers: developers and maintainers, individuals and companies. If you enjoy using OpenWrt, consider contributing some effort to help us improve it for others! All of the above is possible because OpenWrt is part of the Open Source community, and powered by Linux kernel.
Get the source code Like any open source project, OpenWrt thrives on the efforts of its users and developers. If you want to develop the software, please refer to our Developer Guide to learn how to get the source code, build it, and contribute your changes back to the project.
If you're not a developer, you can still help.The goal of this guide is to let you build your own flashable firmware in as few simple steps as possible.
It is intended for Windows users and users who already have a Debian or Ubuntu server. You are required to have a 64 bit version of Windows and at least 8 GB free disk space. Setting up for building on a Mac will be very similar Virtualbox is availablebut I don't have one so I can't test it.
The main advantage of building your own firmware is that it compresses the files, so that you will have room for much more stuff.
It also lets you change some options that can only be changed at build time, for instance the features included in BusyBox and the block size of SquashFS.
Larger block size will give better compression, but may also slow down the loading of files.The amazing human body worksheet answers
As an alternative to setting up a virtual machine, Windows 10 users can install Ubuntu from Microsoft Store and skip to part 2. Make sure to run these commands after installation:. This program will let you run a virtual Linux server on you Windows based computer.
Download the newest version from virtualbox. The interface for changing the keyboard is a bit weird, but you can find the correct place like this:. From now on, whenever you should be in the terminal to type a command the syntax will look like this:. Follow up questions with obvious answers like typing the passsword osboxes.
Cut and paste will unfortunately not work at this moment. Click Devices top lineselect the last option Install Guest Additions. The automatic install does not seem to work, so it doesn't matter if you select cancel or run. After this you will need to start the server again.
Now you can change to a higher resolution so you get a larger window if you like:. And lastly hopefully you can cut and paste now. Note that cut and paste only works for text without any kind of formatting. You may need to copy the text to notepad and then copy it from there to clean it up.
Your virtual Debian server should now be set up correctly for following the rest of the guide. As a bonus, you now have a fully functional Linux computer that you can use for anything, and with the added safety of running it as a virtual machine. This will give you a list of tag names for releases and development branches. Check out the one you want like this:. Then continue following the Quick Image Building Guide. You select a package using space one or more times.
Except for choosing the target I suggest that you don't mess with the options above Base system. Also, in general, don't uncheck anything that is selected by default unless you really know what you're doing.
Instructions on how to include config files in the image for instance from the backup you can download from the router : Custom files. This will take a very long the first time. Don't use the -j option mention in the Quick image building guide, it is asking for trouble. A common mistake is to include packages that are mutually exclusive. After a successful build you can list the generated files using this command:.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It is recommended that you work with the latest sources. Installing in context of. The section and category can be found in the Makefile. Each branch contains the baseline code for the release version e.
Each branch is intended to contain stable code with carefully selected fixes and updates backported from the development branch. To use a branch, you should first clone the Git repository using the git clone command shown above. Then move to the branch by using the git checkout command. When changing branches, it is recommended to perform a thorough scrub of your source tree by using the make distclean command. This ensures that your source tree does not contain any build artifacts or configuration files from previous build runs.
This may be useful when you want to be able to install packages from the repositories for a long time.
The build system configuration interface handles the selection of the target platform, packages to be compiled, packages to be included in the firmware file, some kernel options, etc. Start the build system configuration interface by writing the following command:. This will update the dependencies of your existing configuration automatically, and you can now proceed to build your updated images. You will see a list of options. This list is really the top of a tree. You can select a list item, and descend into its tree.
This will give you its locations within the tree. For most packages and features, you have three options: ymn which are represented as follows:.
When you open menuconfig you will need to set the build settings in this order also shown in this order in menuconfig 's interface :.
Select your device's Target system first, then select the right Subtargetthen you can find your device in the Target profile 's list of supported platforms. Beside make menuconfig another way to configure is using a configuration diff file. This file includes only the changes compared to the default configuration. A benefit is that this file can be version-controlled in your downstream project. It's also less affected by upstream updates, because it only contains the changes.For various reasons, last week I decided to run on it a software pmacctindeed that was NOT included in the official package repository.
Such a scenario was exactly what I was waiting for…. Previously …up to a couple of weeks ago! I already knew that building a software to run on my WDR were going to be not an easy task. Hence I needed to use my PC. Unfortunately my PC is running on a very common x86 platform. Problem 1: how to build a MIPS-executable using a compiler running on an x86 platform? Answer to such a question is quite simple: cross-compilation.
Build system – Installation
As you can see in line 3, the compiler properly built the x version, that actually succesfully run on my Linux box lines 5 and 6. And so? Unfortunately not. Nice result…. This is where things start getting interesting….
Indeed, when you know about SDK…. In such a scenario, my goal is that following notes will result very helpful. Actually, you need an opkg update. Well, you got the point:. So to step further we need to tell the SDK what to do eg. In order to tell the SDK that we want to rebuild the tcpdump package, we simply issue a. Such a command simply:. Now, in this stage, everything is in place and finally we can tell the SDK what we want rebuild tcpdump. By firing the make menuconfig command, that will provide us the well-known curses-based interface, where we can define what we need.
Not to mention that, in our case, is also useless! Remember: we want to rebuild ONLY tcpdump! Nothing more!Referral fee agreement
