Running C++11 programs

Question

I installed gcc4.8 in scientific linux using:

wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo
yum install devtoolset-2

gcc --version gives me: gcc4.8

Now my problem is when I now run C++11 programs on gcc (using netbeans IDE) I get the error:

/home/topK/CppApplication_7/dist/Debug/GNU-Linux-x86/cppapplication_7: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.17' not found (required by /home/topK/CppApplication_7/dist/Debug/GNU-Linux-x86/cppapplication_7)
/home/topK/CppApplication_7/dist/Debug/GNU-Linux-x86/cppapplication_7: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by /home/topK/CppApplication_7/dist/Debug/GNU-Linux-x86/cppapplication_7)

Can someone please help me as to how can I get rid of this error.

Answer 1

My guess is that /usr/lib64/libstdc++.so is the older library which your application is trying to link against... and the newer library is installed somewhere else, which is not on the search path — or if it is on the search path, it comes after the old library, which is why the linker attempts to link against the older one, and fails.

Try doing this:

$ g++ program.cpp -L/path/to/new/stdlib -lstdc++ -Wl,-rpath=/path/to/new/stdlib

where /path/to/new/stdlib is the location of the new library. You can also set this on the beginning of LD_LIBRARY_PATH.

---

Or

You're using older version of g++, and trying to against the newer version of libstdc++.so. Locate g++ and use it. Use all 4 combinations of g++ and libstdc++ (if there are two versions of each of them).

Hope that helps.
