I would like to know if there is a dependency between gcc-version and cpp-extension compilation.
I have tried compiling the standard cpp-extension (LLTM from here 1) example under two gcc version (5.2.0, 6.1.0 with conda), both of them are unable to compile the extension.
The details are given below:
Ubuntu : 14.04
Python version: 3.6.5
Pytorch installation: conda install pytorch-nightly -c pytorch (version 1.0.0.dev20181008)
gcc installation: conda install -c omgarcia gcc-6 or conda install -c cqwz gcc-5
Error in gcc 5.2.0:
g++: error: -fuse-linker-plugin is not supported in this configuration

Error in gcc 6.1.0:
