Hi,
Just in case there is someone like me who cannot build gcc on os x 10.4,
here is the solution: upgrade your Xcode to 2.4.1, or 3.0 if you are using
os x 10.5. Xcode 2.2 is the version came with mac os x 10.4(tiger)
installation DVD.
My configuration:
../src/configure --prefix=/Users/eric/gcc-4.2.1/local --enable-languages=c
Didn't change anything basically.
Initially I got the error message with Xcode 2.2:
In file included from /usr/include/sys/_types.h:26,
from /usr/include/_types.h:27,
from /usr/include/stdio.h:64,
from ../../src/gcc/tsystem.h:90,
from ../../src/gcc/config/darwin-crt3.c:38:
/usr/include/sys/cdefs.h:335:4: error: #error Unknown architecture
...
/usr/include/stdio.h:258: error: parameter name omitted
../../src/gcc/config/darwin-crt3.c:535: error: expected '{' at end of input
make[5]: *** [x86_64/crt3.o] Error 1
make[4]: *** [extrax86_64] Error 2
make[3]: *** [stmp-multilib] Error 2
make[2]: *** [all-stage1-gcc] Error 2
make[1]: *** [stage1-bubble] Error 2
make: *** [bootstrap] Error 2
The host in Makefile:
host=i386-apple-darwin8.10.1
It seems that gcc tries to compile X86_64 code, but the architecture is not
supported. The strange thing is my host is i386, which should not involve
X86_64 code. However, it worked after upgrading to Xcode 2.4.1. The version
of gcc is the same, 4.0.x, but it just worked, maybe due to changes in the
header file.
