GLIBCXX_3.4.9 not found

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:

…/libexec/gcc/i686-pc-linux-gnu/4.2.1/cc1: /usr/lib/ version `GLIBCXX_3.4.9’ not found (required by …/libexec/gcc/i686-pc-linux-gnu/4.2.1/cc1) Generally, it means that the GLIBCXX_3.4.9 does not work with I did not install glibc in /usr/lib at all. Any advice will be appreciated. Thanks a lot in advance. Bin

Did you overwrite your /usr/lib/
As the message says libstdc++ must be at least 3.4.9. What version is

Some distributions have the habit of using an
ancient /usr/lib/libstdc++, and putting the correct one
in /usr/lib/gcc/.../

Best regards,
