I use 'go get' and meet the same problem too.

get get succeeded without errors. this happened on build though:

go get github.com/DataDog/go-python3
errors.go:74:14: could not determine kind of name for C.PyErr_SetImportErrorSubclass
- 'PyErr_SetImportErrorSubclass' has been introduced in Python 3.6
- 'PyImport_GetModule' has been introduced in Python 3.7
To me it looks like you have to update your Python version to v3.7 to get the support for both functions.

Hi,
You will need the dev package for Python3 install that provide the Python.h header which define this all Python function. make sure it's in your resolution path for the compiler too.
Also @piccobit is right, this package is meant for python 3.7.

I fixed it by adding:
Libs: -L${libdir} -lpython3.7m -lutil -lm -ldl
to python3.pc
from go-python3.

If I compile with Python 3.8 I get could not determine kind of name for PyEval_ReInitThreads
from go-python3.

Hi @marcofiocco, the lib only support python 3.7 currently. PyEval_ReInitThreads was removed in 3.8. I fixed the README to make this clear (thanks for raising the issue).
We do not plan on updating this to work with both 3.7 and 3.8 but if you would like to open a PR for this I'll be happy to review it.
I also updated the README to better explain that the python headers are needed to compile this package.
Default workflow looks like this (on Debian for example):
$> apt-get install python3.7-dev
$> go get github.com/DataDog/go-python3
Closing this issue, but feel free to reopen it or open another issue if needed.
