Error compiling pyvle

[rtrepos]

I get this error when compiling pyvle :

/pub/src/vledev/pyvle/src/convert.cpp:52:18: error: ‘PyInt_FromLong’ was not declared in this scope
result = PyInt_FromLong(
^~~~~~~~~~~~~~
/pub/src/vledev/pyvle/src/convert.cpp:52:18: note: suggested alternative: ‘PyLong_FromLong’

I try to compile pyvle with :

• Ubuntu 18.04
• vle master
• Python 2.7.15rc1
• libboost-python1.65-dev

According to [1] the PyLong_FromLong is for Python3. But you can do: #if PY_MAJOR_VERSION >= 3 PyLong_FromLong(...) #else PyInt_FromLong(...) #endif [1] http://python3porting.com/cextensions.html

Thanks,
Yes exactly, but I am using python 2.7.15
and according 2.7.16 documentation it should be available :

https://docs.python.org/2/c-api/int.html

There is something that I d'ont understand here.

Ok I have both python2.7 and python 3.6 installed.
By default python is the version 2.7.
Maybe the Cmake command INCLUDE(FindPythonLibs) search for 3.6 version

[quesnel]

During compilation, you must have the include directories (use make VERBOSE=1).

[rtrepos]

The directive in CMakeList :

EXECUTE_PROCESS(
COMMAND
python -c "from distutils import sysconfig; print sysconfig.get_python_version()"
OUTPUT_VARIABLE PYTHON_VERSION
OUTPUT_STRIP_TRAILING_WHITESPACE
)

return version 2.7, but that is not the version found by cmake.
I will suggest a commit.
