version `CXXABI_1.3.8' not found (required by ...)

Question

When I run my program following a compile, I get the following error:

./prog: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version CXXABI_1.3.8' not found (required by ./prog) ./prog: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: versionGLIBCXX_3.4.19' not found (required by ./prog) ./prog: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /home/arman/lib/boost_1_55_0/stage/lib/libboost_serialization.so.1.55.0)

I have both boost 1.55.0 and gcc 4.9.0 installed in ~/lib/boost_1_55_0 and ~/lib/gcc-4.9.0 respectively, and I'm guessing this is why I'm having problems, but I'm unsure about how to go about fixing it.

my ~/.profile contains the following line:

export LD_LIBRARY_PATH=/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Solution

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

In this case it's likely to be in /home/user/lib/gcc-4.9.0/lib64

For help with qtox (not sure why this page is the first hit for fixing qtox) please see github.com/tux3/qTox/issues/3358#issuecomment-233700842

For those running in an anaconda environment, it will be export LD_LIBRARY_PATH=/path/to/anaconda3/lib
