Where can I find "cpp_functions.so"? Thanks in advance.

This issue is solved. The older version of gcc was directed. I manually export CC and CXX. However, after installation, when I executed porechop, this error showed up could not find cpp_functions.so - please reinstall
cpp_functions.so is already in porechop directory but it cannot be detected.

Sounds like you still are having compiler issues. I would reinstall both Porechop and gcc and try again.

I also get errors installing

I'm using: g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23)

@lab-rat-kid, the README recommends GCC 4.9.1 or later. You might want to try GCC 5.

From the README notes:

If you'd like to specify which compiler to use, set the CXX variable: export CXX=g++-6; python3 setup.py install

I managed to get it installed with GCC 7, but ran into the next error: could not find cpp_functions.so - please reinstall. I finally decided to build and run without installation (i.e., ./porechop-runner.py) instead of fiddling with installing porechop in my conda environment because of this issue.

conda install https://anaconda.org/brown-data-science/gcc/5.4.0/download/linux-64/gcc-5.4.0-0.tar.bz2 I use this command to install gcc-5 in conda environment and it works.
