TensorFlow build fails with `GLIBCXX_3.4.20' not found

Question

Building TensorFlow with gcc version 4.8.5 or 5.4.0 gives an error:

bazel-out/host/bin/external/protobuf/protoc: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by bazel-out/host/bin/external/protobuf/protoc)

Tried to add linker flags in CROSSTOOL.tpl file in Tensorflow, however it didn't help.

Which system is that? If ubuntu, did you tried: sudo apt-get install libstdc++6? — sygi

You built your app with version of GCC that's newer than your host GCC. So your app uses symbols which are not present in host libstdc++ which causes runtime linker to fail.

You can solve this by linking your app with -Wl,-rpath,path/to/new/libs or setting LD_LIBRARY_PATH appropriately.
