|
|
# Wrapper for the "crossdirect" compilation method.
|
|
# pmbootstrap mounts the native chroot in the foreign arch (e.g. armhf) chroot
|
|
# as /native. This package gets installed into the native chroot, and creates
|
|
# wrappers like:
|
|
#
|
|
# /native/usr/lib/crossdirect/armhf/gcc
|
|
# -> /native/usr/bin/armv6-alpine-linux-muslgnueabihf-gcc
|
|
# /native/usr/lib/crossdirect/armhf/rustc
|
|
# -> /native/usr/bin/rustc --target=armv6-alpine-linux-musleabihf ...
|
|
#
|
|
# When building packages in the armhf chroot, PATH will get prepended with
|
|
# "/native/usr/lib/crossdirect/armhf". The end game is of course invoking
|
|
# programs such as cross compilers and archivers from the native chroot,
|
|
# running at native speed, whenever they get called from the foreign arch
|
|
# chroot. See crossdirect.c for implementation details of the C version (llvm,
|
|
# fakeroot, rpath). The rust version and redirect for archivers are implemented
|
|
# as simple shell wrappers.
