I want to use openfst python wrapper on my python application.

When I run 

pip install openfst

for Python 3.6 gave error as the following.

Obviously, it looks like the Visual Studio compiler is complaining about /Wno-unneeded-internal-declaration flag while it is trying to build the C extensions.

The easiest solution would be to download a pre-compiled version that matches your system at their website

Also, based on their site, it seems that they used Visual Studio 2013.You may be able to install and compile it using VS13.
