Building TensorFlow: bazel cannot find libstdc ++ in non-standard directory
I am trying to build an MKL accelerated version of TensorFlow using bazel 0.5.1, gcc 6.2, binutils 2.28, Anaconda2 python on Scientific Linux 7.2. Apparently the / lib 64 / libstdc ++. So.6 system is too old, so I am trying to use gcc installed in a different directory. PATH, LD_LIBRARY_PATH changed to add appropriate paths (using modules). However, while bazel has no problem building the correct binaries for gcc, ld, python, it still tries to load the old / lib 64 / libstdc ++. So.6 system. How do I make it use one of gcc 6.2? Why doesn't it pick it from LD_LIBRARY_PATH? According to Google, a lot of people have problems with this, but I couldn't find a solution that would work for me. I had no problem building TensorFlow under Ubuntu 16.04,which has a fairly new gcc in its standard location.
I am doing:
1) ./configure The only options other than the defaults I choose are to use MKL and load MKL
2) bazel build --config = mkl --copt = "- DEIGEN_USE_VML" -s -c opt // tensorflow / tools / pip_package: build_pip_package

Sorry for the slow response. Bazel by design ignores LD_LIBRARY_PATH when performing actions. It shouldn't ignore them while discovering the C ++ tools, but at the moment it does the following: / To help you forward, I would try to add --sysroot = as linkopt, or use the bazel grte_top flag. Depending on where your libstdc ++ is. This is how it lives, you may need to disable the sandbox. The principal solution would be to write a custom CROSSTOOL that specifies builtin_sysroot or grte_top. But this is not an easy task.
Let me know if I lost you anywhere at this point :)
