[LLVMdev] libstdc++.so.6 problem

[Bin Zeng]

  Hi all,

I am really stumped on this problem. I googled and could not find any
solution. Here is the problem. I compiled and installed
glibc-2.5-20090518 in a local directory with gcc version 4.1.2.  I
compiled glibc-2.5 because I wanted to test glibc-2.5 on gcc first
llvm-gcc. However, after I installed glibc, llvm-gcc does not work
any more. It reported this error message:

/root/tools/llvm/llvm-gcc/install/bin/../libexec/gcc/i686-pc-linux-gnu/4.2.1/cc1: 

/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required
by 
/root/tools/llvm/llvm-gcc/install/bin/../libexec/gcc/i686-pc-linux-gnu/4.2.1/cc1)

It says that the GLIBCXX_3.4.9 does not work with libstdc++.so.6. I did 
not install glibc in /usr/lib.  /usr/lib/libstdc++.so.6 should not be 
affected.
Also rpm shows that the version is:

[root at localhost gold]# rpm -q glibc
glibc-2.5-34.el5_3.1

Any advice will be appreciated. Thanks a lot in advance.
