[LLVMdev] glibc compilation

[Bin Zeng]

  Hi All,

Did anyone try to compile glibc with llvm-gcc or clang? I tried to 
configure glibc with CC=llvm-gcc and it failed with this message:

...
checking for a BSD-compatible install... /usr/bin//install -c
checking whether ln -s works... yes
checking for gcc... llvm-gcc
checking for suffix of object files... configure: error: cannot compute 
suffix of object files: cannot compile
See `config.log' for more details.
...

In `config.log', the erros message is like this:
configure:2776: checking for suffix of object files
configure:2797: llvm-gcc -c   conftest.c >&5
/root/tools/llvm/llvm-gcc/install/bin/../libexec/gcc/i686-pc-linux-gnu/4.2.1/cc1:

Does anyone know anything about it? Thanks a lot in advance.
