This repository contains a Docker file which can be used to create Docker images with specific ARM GCC compiler and glibc versions. Its purpose is to be able to compile a project with those specific versions which it was developed with.
There is prebuild ready-to-use Docker images available on Docker Hub. Use it like this.
In your project, create a shell script for the ARM compiler executable. You can name the file arm-linux-gnueabihf-g++-9 which is the exact name of the ARM compiler executable inside the Docker container. Put the following content inside of it and replace the X with the version you want, for example gcc-9.3.0_glibc-2.31.
#!/bin/sh
docker run --rm --entrypoint arm-linux-gnueabihf-g++-9 --volume $PWD:/hostdir coderitter/coderitter/gcc-arm-glibc-frozen-versions:gcc-X.X.X_glibc-X.XX "$@"
This call to docker run will create a temporary Docker container with the current directory mounted into Docker container. It then executes the ARM compiler executable and forwards any parameters which were made when the script was executed.
The last step is to set the permission of the file so that is executable.
chmod a+x arm-linux-gnueabihf-g++-9Now you can use the script as if the compiler itself was installed in your host system.
./arm-linux-gnueabihf-g++-9 -std=c++17 -Wall -o build/firmware.aThe directory dockerhub contains the Docker Hub readme and Coderitter specific scripts to build the image.
