Comment:
I just tried compiling HEAD with host = build = target = x86_64-apple-
darwin on my OSX (10.6.5) machine (64-bit processor; kernel is booted as
64-bit as well), and it fails with:
{{{
"/usr/bin/gcc" -o utils/unlit/dist/build/tmp/unlit -m64 -fno-stack-
protector utils/unlit/dist/build/unlit.o
ld: warning: in utils/unlit/dist/build/unlit.o, file was built for i386
which is not the architecture being linked (x86_64)
Undefined symbols:
"_main", referenced from:
start in crt1.10.6.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make[1]: *** [utils/unlit/dist/build/tmp/unlit] Error 1
make: *** [all] Error 2
}}}
I'll hazard a guess that this is because the configure scripts for
libraries/integer_gmp and libraries/unix are autodetecting host, build,
and target as i386. Shouldn't libraries inherit host, build, and target
from the "overall" configure script a la [wiki:CrossCompilation]?
For reference, a standard i386 build (no configure options) does pretty
well, until it inexplicably fails in stage 2 with "make[1]: ***
[libraries/vector/dist-install/build/Data/Vector/Fusion/Stream/Monadic.o]
Bus error", but that's for another ticket. :)
