buildroot-sdk-builder

Use buildroot to build a basic SPARC, MIPS, ARM, or AARCH64 Linux GNU C/++ toolchain and package it for Debian/Ubuntu.

All SPARC GNU tools are prefixed with sparc-linux. ie, sparc-linux-gcc, sparc-linux-as, sparc-linux-ld, etc. Tools for other architectures are prefixed similarly.

SPARC executables can be executed using the sparcexec command. mipsexec can be used for MIPS binaries, armexec for ARM binaries, and aarch64exec for ARM64 binaries.

# For example...
$ printf '#include <stdio.h>\nint main(void) { puts("Hello, World!"); }' > hello.c
$ sparc-linux-gcc hello.c -o hello
$ sparcexec hello
Hello, World!

Building

Before building anything, you will need to install buildroot's dependencies. Buildroot also requires that you have no whitespace characters in your PATH.

Currently supported values for ARCH are sparc, mips, arm, and aarch64. The default value is sparc.

For Debian/Ubuntu

Building for Debian/Ubuntu requires dpkg-dev.

make debian           # SPARC is the default target
make debian ARCH=mips # but other arcitectures is also suppoted

This will build the toolchain and package it for Debian/Ubuntu systems.

For Other Systems

Build the toolchain and install it with make.

make
sudo make install
make ARCH=mips
sudo make install ARCH=mips

This will install the toolchain to /opt/sparc-buildroot-linux-uclibc_sdk-buildroot. If necessary, you can uninstall the it with sudo make uninstall.

For Docker

Building for Docker requires dpkg-dev. You can also use Podman for this.

make docker
make docker ARCH=mips

This will build a docker container with the tag (ARCH)-linux-toolchain.
Here is an example of how to compile and run a local C file using the Docker container. This example uses SPARC.

docker run --rm -v "$PWD":/src -w /src sparc-linux-toolchain sparc-linux-gcc hello.c -o hello
docker run --rm -v "$PWD":/src -w /src sparc-linux-toolchain sparcexec hello

If you just want the docker image without building the toolchain from scratch, you can download the corresponding deb package for your desired architecture from the latest release, place it the directory of this README, and follow the above instructions, changing the necessary make variables when applicable.

Just The Toolchain

make
make ARCH=mips
