Hi, I'm trying to build llvm-gcc-4.2 on Ubuntu 11.04 (the Natty Narwhal).

Anyone know what to do about this? I found: https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/738098 which is supposedly fixed in binutils .2.21.0.20110322-1ubuntu2. But I've got a slightly later binutils than that, and I'm still having this problem. Thanks, Jay.

[LLVMdev] building llvm-gcc on Ubuntu 11.04 Natty Narwhal
Hi Jay,> I'm trying to build llvm-gcc-4.2 on Ubuntu 11.04 (the Natty Narwhal).I can build it here on x86-64 natty without any problems. Ciao, Duncan.
>> I'm trying to build llvm-gcc-4.2 on Ubuntu 11.04 (the Natty Narwhal). > > I can build it here on x86-64 natty without any problems.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.
