Tensorflow binding - setup.py showing error

[karanMal]

Error: Unrecognised command line option -R in g++
please see the below logs -

python setup.py install --user CUDA_HOME not found in the environment so building without GPU support. To build with GPU support please define the CUDA_HOME environment variable. This should be a path which contains include/cuda.h setup.py:66: UserWarning: Assuming tensorflow was compiled without C++11 ABI. It is generally true if you are using binary pip package. If you compiled tensorflow from source with gcc >= 5 and didn't set -D_GLIBCXX_USE_CXX11_ABI=0 during compilation, you need to set environment variable TF_CXX11_ABI=1 when compiling this bindings. Also be sure to touch some files in src to trigger recompilation. Also, you need to set (or unsed) this environment variable if getting undefined symbol: _ZN10tensorflow... errors warnings.warn("Assuming tensorflow was compiled without C++11 ABI.
