CrossBuild Initial Release
CrossBuild Provides a Dockerfile to build a container that supports cross compilation for ARMv7 and i686 targets from x86-64 hosts.
This project was created out of a need to have a single-shot process for building a few Rust projects with stripped binaries featuring static C-runtimes for:
While cross exists, and is far more full featured, the project lags behind in updating the base OS, GCC, and QEMU versions used (as of this writing).
An example exists that handles my specific use case for one project, and might serve as inspiration for modifications to suit more complicated needs.
