I'm trying to make a cross-compiler on an i386 linux box to a ppc darwin (OSX) box. I downloaded binutils, configured them with ./configure --target=powerpc-apple --prefix=/usr/local Build them, and installed them. Then I went and got gcc (with g++), configured it with: ./configure --target=powerpc-apple-darwin --prefix=/usr/local I also made a symlink from /usr/local/powerpc-apple -> /usr/local/powerpc-apple-darwin since it seemed to fix a problem in the gcc compile. When I try to build gcc, it goes for a minute or so, and then I get this towards the end: libbackend.a(varasm.o): In function `assemble_alias': /data/hughesm/tmp/gcc-3.1/gcc/varasm.c:5184: undefined reference to `ASM_OUTPUT_DEF' collect2: ld returned 1 exit status make[1]: *** [cc1] Error 1 make[1]: Leaving directory `/data/hughesm/tmp/gcc-3.1/gcc' make: *** [all-gcc] Error 2 I'm not really asking for the exact cause of the error... I'm just trying to figure out if I'm even going about this the correct way. The documentation on cross compiling is a bit sparse. It seems odd to me that the targets don't match (but there is no powerpc-apple-darwin in binutils, and no powerpc-apple in gcc) All that being said, I'm doing this so I can add my linux boxes to my OSX build farm. Check out distcc.samba.org for a wicked cool and easy way to distribute compiles. -Marc
