PyFst Install Ubuntu Error Command 'x86_64-linux-gnu-gcc' failed with exit status 1

Question

With Python 2.7.12 and Ubuntu 16.04.2 LTS, I tried following instructions @ PyFST Setup CMU to install OpenFst and pyfst but fails with error

note: candidate expects 16 arguments, 15 provided error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

and also tried @ PyFST Setup OGI but fails with

`

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Looks like OpenFst is setup properly because I am able to see fst commands.

However, I get this error when I try to run sudo pip install pyfst

...(only including a snippet of the error message because longer than the terminal window)

----------------------------------------

Command "/usr/bin/python -u -c "import setuptools, tokenize;file='/tmp/pip-build-DngJ9w/pyfst/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-FFhvRI-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-DngJ9w/pyfst/

Or I try the following:

wilson@wilson-300V3A-300V4A-300V5A:~/demo/openfst-1.6.2$ 
wilson@wilson-300V3A-300V4A-300V5A:~/demo/openfst-1.6.2$ echo 'export CPLUS_INCLUDE_PATH=$PREFIX/include:$CPLUS_INCLUDE_PATH

> export LD_LIBRARY_PATH=$PREFIX/lib/fst:$LD_LIBRARY_PATH
> export PATH=$PREFIX/bin:$PATH
> export PYTHONPATH=$PREFIX/lib/python2.7/site-packages:$PYTHONPATH' >> ~/.bashrc

Which appears to work fine

Answer 1

Don't use PyFST, it's out of date. Python bindings are included with OpenFST since approximately version 1.5.1. Just install OpenFST as normal, with the --enable-python:

./configure --enable-python
make
sudo make install

That should put the Python libraries in the appropriate places.

Some additional information is available on the OpenFST website.
