llvm dev - Jun 2010 - [LLVMdev] Error while compiling mysql using LLVM-gold

Hello,

I am trying to compile mysql using LLVM and I am found the following
"If you just want to use *LLVM*'s link-time optimizations, you will
need to
use the libLTO library with your linker.  Your linker, in turn, must be
able to support plugins (like the gold linker, for example).  For
directions on how to set up libLTO, see
http://*llvm*.org/docs/LinkTimeOptimization.html 
<http://llvm.org/docs/LinkTimeOptimization.html> and
http://*llvm*.org/docs/GoldPlugin.html 
<http://llvm.org/docs/GoldPlugin.html>. "
at http://old.nabble.com/Compile-a-large-project-with-llvm--td27793811.html

However, I got
"...
checking for gcc... llvm-gcc -use-gold-plugin
checking for C compiler default output file name...
...
configure: error: C compiler cannot create executables
..."
when I following those instructions.

Any experience on compiling autotooled projects using LLVM is welcome. 
Some online resource on this topic will be great. I am new to this list, 
and I guess this topic may be discussed before.

Thanks,
Guoliang

Can you look in the config.log to see what the error was? Can you use
llvm-gcc -use-gold-plugin in the command line?

The errors are
/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found
/lib/libc.so.6: version `GLIBC_2.7' not found

I can not use it in the command line...
