cross-compiler

==============

C/C++ Cross compiling environment containers

This has been designed to run libtorrent-go cross compilation and is not meant to be perfect nor minimal. Adapt as required.

• CROSS_TRIPLE
• CROSS_ROOT
• LD_LIBRARY_PATH
• PKG_CONFIG_PATH

Also adds CROSS_ROOT/bin in your PATH.

Based on Debian Bullseye (installed from archive.debian.org, as Bullseye is EOL):

• bash
• curl
• wget
• pkg-config
• build-essential
• make
• automake
• autogen
• libtool
• libpcre3-dev
• bison
• yodl
• tar
• xz-utils
• bzip2
• gzip
• file
• rsync
• sed
• upx

And a selection of platform specific packages (see below).

• android-arm, android-arm64, android-x64, android-x86 (Android NDK r20b standalone toolchain, clang, API 21 / Android 5.0+)
• darwin-x64, darwin-arm64 (osxcross with macOS SDK 13.3, clang-16, minimum macOS 13.0)
• linux-armv6 (Raspberry Pi Linaro gcc toolchain, arm-linux-gnueabihf)
• linux-armv7 (crossbuild-essential-armhf, gcc 10)
• linux-armv7_softfp (crossbuild-essential-armel, gcc 10, -mfloat-abi=softfp)
• linux-arm64 (crossbuild-essential-arm64, gcc 10)
• linux-x64 (gcc 10)
• linux-x86 (gcc 10 with -m32, gcc-multilib)
• windows-x64 (mingw-w64 x86_64, gcc 10)
• windows-x86 (mingw-w64 i686, gcc 10)

Either build all images (4 in parallel by default) with:

make

Use make JOBS=1 to build one image at a time with full live output, or make JOBS=8 for more parallel builds.

Or selectively build platforms:

make darwin-arm64

Release is done by running release.sh script, that compiles all Docker images and pushes them to Docker Hub.
