Fasttext: "Unsupported compiler"

[premrajnarkhede]

Hi

I have been using fasttext for long time but when I am trying to install this on new server. I am not able to go past this "Unsupported compiler error"

I am wondering what's happening here as my gcc version seems to be quite new. Existing discussions on similar issues are not able to help.

Error is as follows
Running setup.py install for fasttext ... error
ERROR: Complete output from command /home/premraj/anaconda2/bin/python -u -c 'import setuptools, tokenize;__file__='"'"'/tmp/pip-req-build-wus7qk/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /tmp/pip-record-_ACfNY/install-record.txt --single-version-externally-managed --compile:
