llvm dev - May 2011 - [LLVMdev] building llvm-gcc on Ubuntu 11.04 Natty Narwhal

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.

Hi Jay,

I wasn't using the gold linker.  However if I do (built today) then I get
the
following:

The llvm-gcc build fails with:

/usr/local/bin/ld: warning: wildcard match appears in both version
'GCC_3.0' and
'GCC_4.3.0' in script
/usr/local/bin/ld: error: cannot find -lc

This can be worked around using LIBRARY_PATH.

Ciao, Duncan.

OK, that explains the difference. I installed package binutils-gold ages ago.

I've reported this as a bug against ld.gold here:

Yes, this works for me too -- thanks!

Jay.
