zpugcc-docker is a Docker container for ZPU GCC toolchain.
Why? Because ZPU GCC binary runs on 32-bit Linux only (and on Cygwin…), and compiling it from source isn't easy. On the other hand, this container runs wherever Docker runs.
Create Dockerfile at the root of your project (that you want to compile with ZPU toolchain). Reference shamrin/zpugcc container, add directories you want toolchain to access, and run commands you need for the build (make, cmake, zpu-elf-gcc and others are available). Example Dockerfile:
from shamrin/zpugcc
add zpu /root/zpu
add host /root/host
run mkdir -p /root/zpu/build && cd /root/zpu/build && cmake .. && make
You can then run docker build and copy the result with docker cp. For example:
docker build --rm -t zpu-build .
docker cp $(docker run -d zpu-build true):/root/zpu/build/umtrx/umtrx_txrx_uhd.bin .
Note: building with docker run -v is easier than with docker build and docker cp, but -v option doesn't work on Mac OSX or Windows, yet.
(optional)
docker build --rm -t shamrin/zpugcc .
docker push shamrin/zpugcc
(optional)
On any Ubuntu/Debian (despite the warning, Docker is not required at this point: because -t option):
sudo apt-get install debootstrap
curl -O https://raw.githubusercontent.com/dotcloud/docker/fa8f89c5212f109/contrib/mkimage-debootstrap.sh
chmod +x mkimage-debootstrap.sh
./mkimage-debootstrap.sh -a i386 -t ubuntu32.tar.bz2 precise
Copy ubuntu32.tar.bz2 to any platform supported by Docker and run:
cat ubuntu32.tar.bz2 | docker import - shamrin/ubuntu32
docker run -i -t shamrin/ubuntu32 bash -c 'apt-get -y install file; file /bin/bash'
The last command should output ELF 32-bit:
/bin/bash: ELF 32-bit LSB executable, Intel 80386…
Pushing to Docker registry:
docker push shamrin/ubuntu32
