make：在pkg-config搜索路径中找不到python软件包

Question

$ make
pip install runcython
Requirement already satisfied: runcython in d:\programfiles\conda\lib\site-packages
Requirement already satisfied: Cython>=0.10 in d:\programfiles\conda\lib\site-packages (from runcython)
makecython++ stitch_wrapper.pyx "" "stitch_rects.cpp ./hungarian/hungarian.cpp"
Package python was not found in the pkg-config search path.
Perhaps you should add the directory containing `python.pc'
to the PKG_CONFIG_PATH environment variable
No package 'python' found
stitch_wrapper.cpp:4:20: fatal error: Python.h: No such file or directory
 #include "Python.h"
                    ^
compilation terminated.
make: *** [all-python2] Error 1

Trying to compile some utils written in c++, but get this error:

Package python was not found in the pkg-config search path.

Utils folder includes .cpp and .py files (uses also Python for something)

I have python 3.6.1

make: *** [all-python2] Error 1

Seems it wants python 2.

But I'm not sure if after installing python 2.* and adding it to system variables issue will disappear . Who know for sure?

update

though makefiles has python 3 lines:

SHELL := /bin/bash

.PHONY: all-python2 all-python3
all-python2:
    pip install runcython
    makecython++ stitch_wrapper.pyx "" "stitch_rects.cpp ./hungarian/hungarian.cpp"

all-python3:
    pip3 install runcython3
    makecython3++ stitch_wrapper.pyx "" "stitch_rects.cpp ./hungarian/hungarian.cpp"

Answer 1

For me on Arch Linux (4.15.11-1), makecython was unable to find python.pc too. I checked pkg-config --variable pc_path pkg-config and found out that the respective searchpath only contained the files python3.pc and python2.pc .

So I added a symlink using sudo ln -s /usr/lib/pkgconfig/python3.pc /usr/lib/pkgconfig/python.pc and now everything is working fine.
