🛠️🐋 Crosstool-docker

Crosstool-docker is a framework for building docker images with crosstool-ng toolchains installed.

The image name is roobre/crosstool-ng by default, but can be overridden by setting DOCKER_BASENAME.

build.sh will create the following docker images:

• roobre/crosstool-ng:buildtools: buildtools image is an alpine-based image containing most tools needed for compiling C and C++ code. Apart from GCC and libs, it also includes:

  • git, wget and curl, for fetching packages and repos
  • astyle, clang-analyzer, clang-extra-tools and valgrind, for static analysis and linting
  • doxygen, for generating docs
  • reviewdog, for commenting on CI pull requests

• roobre/crosstool-ng:crosstool: crosstool is the buildtools image plus the installation of crosstool-ng itself. This image is used to generate the target toolchain based on config files.

• roobre/crosstool-ng:*: Images containing toolchains are created from config.* files present in the WD when invocating build.sh. Said script will copy each config.* inside the crosstool image, and run crosstool-ng to produce a toolchain using it. This toolchain will be installed into what will be the final image, based on buildtools, and tagged as roobre/crosstool-ng:*, where * is the suffix of each config.* file.

  • The resulting image will not have crosstool-ng installed, only the produced toolchain.

TODO

• Create a configs/ dir, for better organization.
• Provide a better way of generating config files for crosstool-ng.
