Description Johannes Geiss 2019-11-21 13:45:10 UTC
Building a cross development system with the current (1.1.24) musl produces unusable static libraries.

Reproducible: Always

Steps to Reproduce:
export CT=armv7el-unknown-linux-musleabihf
crossdev --stable -oS gentoo -oO /usr/local/portage --target $CT

cat >HelloWorld.c <<EOF
#include <stdio.h>

int main(void)
{
    puts("Hello World!");
    return 0;
}
EOF

$CT-gcc -o HelloWorld HelloWorld.c
$CT-gcc -static -o HelloWorld HelloWorld.c


Actual Results:  
/usr/libexec/gcc/armv7el-unknown-linux-musleabihf/ld: skipping incompatible /usr/armv7el-unknown-linux-musleabihf/usr/lib/libc.a when searching for -lc

Expected Results:  
Static executable without the linking error.

Comment 1 Sergei Trofimovich (RETIRED) gentoo-dev 2019-11-21 17:23:12 UTC
I think musl will need an equivalent of strip avoidance: 
https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-libs/glibc/glibc-9999.ebuild#n1202
Comment 2 Sergei Trofimovich (RETIRED) gentoo-dev 2019-11-21 17:24:42 UTC
As a workaround you can rebuild cross-musl package with FEATURES=nostrip to get working objects.
Comment 3 tt_1 2020-03-13 19:54:09 UTC
was this fixed in musl-1.2.0?
Comment 4 Sergei Trofimovich (RETIRED) gentoo-dev 2020-03-13 22:33:46 UTC
If you see no activity in the bug and no equivalent of:

    # Avoid stripping binaries not targeted by ${CHOST}. Or else
    # ${CHOST}-strip would break binaries build for ${CTARGET}.
    is_crosscompile && dostrip -x /

in the ebuild then probably not. Especially given that ebuild is EAPI=6.

I am unable to reproduce with aarch64, I will test with my armv7a toolchain and see if I can duplicate this there.

Please crossdev -C armv7el-unknown-linux-musleabihf start fresh and test again. I am unable to duplicate even with the armv7a cross toolchain.

Looks to me like a toolchain issue...
Comment 8 Sergei Trofimovich (RETIRED) gentoo-dev 2020-05-21 06:25:11 UTC
To be able to reproduce it you need your host binutils built with USE=-multitarget.

The good hint is usually complains of binutils to try to strip it:

Wrong strip should never be ran on binaries it does not understand.
