This is a script to build GCC toolchains targeting arm, arm64, and x86 devices (primarily Android devices).
To build a toolchain, you will need to the following:
- A Linux distribution (the script has been tested on Ubuntu 17.04 and Arch Linux)
- A decent processor and RAM (i5 and 8GB of RAM or more is preferred)
- Core developer packages
- For Arch:
sudo pacman -S base-devel git - For Ubuntu:
sudo apt-get install flex bison ncurses-dev texinfo gcc gperf patch libtool automake g++ libncurses5-dev gawk expat libexpat1-dev python-all-dev binutils-dev libgcc1:i386 bc libcloog-isl-dev libcap-dev autoconf autoconf-archive libgmp-dev build-essential gcc-multilib g++-multilib pkg-config libmpc-dev libmpfr-dev autopoint gettext liblzma-dev libssl-dev libz-dev
- For Arch:
Once you have set up your environment, run the following:
git clone https://github.com/USBhost/build-tools-gcc
cd build-tools-gcc
./build -hThe printout will show you how to run the script.
Example commands:
# Build a GNU 8.x toolchain for x86_64
./build -a x86_64 -s gnu -v 8 -V
# Build a Linaro 7.x toolchain for arm64
./build -a arm64 -s linaro -v 7 -V
# Build a Linaro 5.x toolchain for arm
./build -a arm -s linaro -v 5 -VOnce it is done building, you will have a folder with the compiled toolchain as well as either a tar.xz or tar.gz file (depending on if you passed -p or not).
If the toolchains are compressed, move them into your directory of choice and run the following commands:
For xz compression:
tar -xvf <toolchain_name>.tar.xz --strip-components=1For gz compression:
tar -xvzf <toolchain_name>.tar.gz --strip-components=1After that, point your cross compiler to the proper file and compile! This is an easy shortcut for kernels (when run in the directory you extracted the toolchain in):
# for arm64
export CROSS_COMPILE=$(pwd)/bin/aarch64-linux-gnu-
# for arm
export CROSS_COMPILE=$(pwd)/bin/arm-linux-gnueabi-If you have any issues with this script, feel free to open an issue!
Pull requests are more than welcome as well. However, there is a particular coding style that should be followed:
- All variables are uppercased and use curly braces:
${VARIABLE}instead of$variable - Four spaces for indents
- Double brackets and single equal sign for string comparisons in if blocks:
if [[ ${VARIABLE} = "yes" ]]; then
Additionally, please be sure to run your change through shellcheck.net (either copy and paste the script there or download the binary and run shellcheck build).
