Do you have any /lib64/libc.so* or /usr/lib64/libc.so* ?

Are you still setting LIBRARY_PATH or LD_LIBRARY_PATH, as mentioned in:

https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/738098

?

Thanks,
Jay.

no.

Indeed I'd forgotten about this: I have LIBRARY_PATH set to
/usr/lib/x86_64-linux-gnu/

If I unset LIBRARY_PATH then llvm-gcc-4.2 still builds.

Ciao, Duncan.

Duncan,

Can you try another experiment please? I get:

$ ls -l `which ld`
lrwxrwxrwx 1 root root 7 2011-05-06 19:26 /usr/bin/ld -> ld.gold
$ ld.gold -lc
ld.gold: error: cannot find -lc
$ ld.bfd -lc
ld.bfd: warning: cannot find entry symbol _start; not setting start address

What do you get?

Thanks!
Jay.
