Hi,
I did a bootstrap of clang's release 2.9 branch today, I would like to
build all of GNUstep with clang but already failed building libobjc2.
address@hidden:~/gnustepsvn/devmodules/dev-libs/libobjc2$
make debug=no
This is gnustep-make 2.4.0. Type 'make print-gnustep-make-help' for help.
Running in gnustep-make version 2 strict mode.
Making all for library libobjc...

Looks like the path to my crtBeginS.o is missing, namely
/usr/lib/gcc/x86_64-linux-gnu/4.2. Is this the same issue as with the
c++ headers which have to be known by clang already at bootstraptime?
Or do I simply need some magic incantation?
I am on Ubuntu 8.04 AMD64 (old but not ancient)
gcc -v
Es werden eingebaute Spezifikationen verwendet.

gcc-Version 4.2.4 (Ubuntu 4.2.4-1ubuntu4)
clang -v
clang version 2.9 (branches/release_29 127463)
Target: x86_64-unknown-linux-gnu
Thread model: posix

Thanks
