Description Saul Wold 2017-04-12 18:27:08 UTC

Currently we have both MUSL and x32 support, but they are independant, MUSL is working on x32 support and is currently experimental.  We should ensure that the meta-data and bbclasses are prepared for being able to build a combination of both.

A starting point would be to build for MUSL and corei7, then test with changing the DEFAULTTUNE

TCLIBC = "musl"
MACHINE="intel-corei7-64"
#DEFAULTTUNE = "corei7-64-x32"

There will be both infrastructure changes (bbclass) and possible bug fixes to various projects (upstream and recipes).

Need to rework on review comments.

Started to look into this issue by referred to gnux32 implementation. 

Made some changes on siteinfo.bbclass and insane.bbclass to support muslx32 for infrastructure change such as osinfo and targetinfo.

Do some fixes on openssl, libffi and perl compilations errors. Currently having systemd-boot do_compile error.

Able to build core-image-minimal image with muslx32 currently. 
However, there are still couple recipes having compilation error with muslx32 when performed bitbake world. 

Created separate Bugzilla bug to keep track those recipes that failing with muslx32 compilation during bitbake world.
