Comment (by ambroff):
This happened in my cross-compilation attempt today as well, using
{{{
../configure ... --build-cross-tools x86_gcc2 ../../buildtools
}}}
The problem is this block here from
src/system/libroot/posix/musl/math/x86/Jamfile:
{{{
if $(architecture) = x86_gcc2 {
# GCC 2 miscompiles some of the files in here, so we use GCC 8.
original_TARGET_CC_x86_gcc2 = $(TARGET_CC_x86_gcc2) ;
TARGET_CC_x86_gcc2 = $(TARGET_CC_x86) -Wa,-mrelax-relocations=no -Wno-
unused-but-set-variable ;
}
}}}
If you look in generated.x86_gcc2/build/BuildConfig, the only packaging
arch is only set to x86_gcc2
{{{
HAIKU_PACKAGING_ARCHS ?= x86_gcc2 ;
}}}
So there is no secondary arch. I haven't completely untangled the
evaluation from TARGET_CC_x86_gcc2 and TARGET_CC_x86, but I suspect that
since the x68 arch isn't defined as a secondary arch that TARGET_CC_x86
will evaluate to empty.
I'll have more time after work to dig into this.
