OpenWRT SDK for GL.iNet devices

OpenWRT SDK for GL.iNet devices. The OpenWRT SDK is a pre-compiled environment suitable for creating custom packages without having to compile the entire OpenWRT build environment.

:!: Do everything as normal user, don't use root user or sudo!

System requirements

x86_64 platform
Ubuntu or another linux distro

Compiling under Windows can be done using the Windows Subsystem For Linux (WSL) with Ubuntu installed to it. Follow the guide bellow, installing Ubuntu 18.04 LTS from the Microsoft Store:

https://docs.microsoft.com/en-us/windows/wsl/install-win10

Preparing your build environment

To use the SDK on your system will usually require you to install some extra packages.

For Ubuntu 18.04 LTS, run the following commands to install the required packages:

$ sudo apt update && sudo apt upgrade -y

$ sudo apt install asciidoc bash bc binutils bzip2 fastjar flex gawk gcc genisoimage gettext git intltool jikespg libgtk2.0-dev libncurses5-dev libssl1.0-dev make mercurial patch perl-modules python2.7-dev rsync ruby sdcc subversion unzip util-linux wget xsltproc zlib1g-dev zlib1g-dev -y

Downloads

$ git clone https://github.com/gl-inet/sdk.git

The SDK requires a "case sensitive" system, Windows is unfortunately not. To run the SDK in WSL you MUST clone the repo to the linux folder tree, ie: /home/<username>/ or any other folder you choose. This is required, you CAN NOT run it from /mnt/c/ or any other windows native drive mounted in WSL. Running the SDK from a Windows mounted disk will result in a failed build with cryptic messages.

For ease of use, We store the SDK separately. You can download the specified SDK by the following command.

$ ./download.sh 
Usage: 
./download.sh [target]   # Download the appropriate SDK

All available target list:
    ar71xx-1806     # usb150/ar150/ar300m16/mifi/ar750/ar750s/x750/x1200
    ath79-1907      # usb150/ar150/ar300m/mifi/ar750/ar750s/x750/x300b/xe300/e750/x1200 openwrt-19.07.7 ath79 target

    ramips-1907     # mt1300 mt300n-v2/mt300a/mt300n/n300/vixmini
    ipq806x-qsdk53  # b1300/s1300
    ipq_ipq40xx-qsdk11  # b1300/s1300/ap1300/b2200 (version 3.201 and above)
    ipq_ipq60xx-qsdk11  # ax1800
    mvebu-1907      # mv1000
    siflower-1806   # sf1200/sft1200
    ipq807x-2102   # ax1800/axt1800 (version 4.x and above)

Compiling

Official compilation method

Place your package in sdk/<version>/<target>/package/, then run:

$ cd sdk/<version>/<target>/
$ make package/<package_name>/compile V=s

For example, to compile the OpenSSL package for the ar71xx target, it will look like this:

$ cd sdk/1806/ar71xx
$ make package/openssl/{clean,compile} V=s

The compiled package will be in the sdk/<version>/<target>/bin/ folder

It is recommended that you use the V=s flag at the end of the make command, but it is not required. The compiler will print all messages and show if there are any errrors. If you know the packages are all correct, you can omit it for a more clean output.

Some packages require other packages to compile. If your package gives warnings like this:

WARNING: Makefile 'package/ddserver/Makefile' has a dependency on 'uclibcxx', which does not exist

Before the compilation begins, or when compiling with the V=s flag you get an error towards the end like this:

Package ddserver is missing dependencies for the following libraries:
libuClibc++.so.0

You will need to install the dependency before compiling your package. To do that run:

$ ./scripts/feeds update -f

This will update the package lists, then run:

$ ./scripts/feeds install <dependency_name>

For the example above, it required the uClibc++ library, so we install it:

$ ./scripts/feeds install uclibcxx

Re-run the make package/<package_name>/compile V=s command and your package should compile without issues.

To make a custom package from any program you can follow the guides here:

https://github.com/mwarning/openwrt-examples

And read about the OpenWRT package structure here:

https://openwrt.org/docs/guide-developer/packages

GL.iNet Util compilation method

We provide a script to compile all software packages with all targets SDK or compile all software packages with a single target SDK. You are freely and quickly compile packages for each platform.

$ ./builder.sh 
Usage: 
./builder.sh [option]
command:
    [-a]                # Compile all software packages with all targets.
    [-t] [target]       # Compile packages with single targets.
    [-d] [package_path] # Package path.
    [-v]                # Enable compile log.

All available target list:
    ar71xx-1806     # usb150/ar150/ar300m16/mifi/ar750/ar750s/x750/x1200
    ath79-1907      # usb150/ar150/ar300m/mifi/ar750/ar750s/x750/x300b/xe300/e750/x1200 openwrt-19.07.7 ath79 target
    ramips-1806     # mt300n-v2/mt300a/mt300n/n300/vixmini
    ramips-1907     # mt1300 mt300n-v2/mt300a/mt300n/n300/vixmini
    ipq806x-qsdk53  # b1300/s1300
    mvebu-1907      # mv1000
    siflower-1806   # sf1200/sft1200
    ipq807x-2102   # ax1800/axt1800 (version 4.x and above)

You can put all your packages to a folder, then run the following command to compile packages for the specified platform,

$ ./builder.sh -d [packages_path] -t [target]

Or run the following command to compile packages for all platform,

$ ./builder.sh -d [packages_path] -a

Installing

Once the package has been compiled, you can transfer the package via SSH to the GL-iNet device following the guides here:

https://docs.gl-inet.com/en/3/app/ssh/

Then running:

$ opkg install <package_name>.ipk

Will install the package on the device without internet.

gl-inet / sdk
