I have a problem concerning libstdc++.so
.
I installed a new version of gcc and tried to compile C++ code. The compiling worked, but when I try to execute the binary (m5.opt
is its name) I've got the following error:
build/ALPHA_SE/m5.opt: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by build/ALPHA_SE/m5.opt).
Do I need to replace libstdc++.so
? And if so, where can I download the version I want? On the GCC-website they say libstdc++ is a part of gcc now.

GCC:
I had gcc 4.1.2 before, but I downloaded gcc 4.2.4. From the untarred gcc-directory I executed ./configure
; make; sudo make install`.
When I tried to use gcc or g++ to compile, it's default version was still 4.1.2. To overcome this I replaced some links:
mv /usr/bin/gcc /usr/bin/gcc_bak
ln -s /usr/local/bin/gcc gcc
mv /usr/bin/g++ /usr/bin/g++_bak
ln -s /usr/local/bin/g++ g++
GLIBC(++) -- libstdc++:
/usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.8
/usr/local/lib/libstdc++.so -> libstdc++.so.6.0.9
/lib/libc.so.6 -> libc-2.5.so -> libc-2.5.so
Linux-version:
uname -a
gives:
