Undefined reference - despite lib being found by linker

Question

I have a trivial program to test for availability of python development files:

#include
int main(){Py_Initialize(); Py_Finalize(); }
<         


        

Answer 1

I encountered the same linking problem as well. But in my case it was not enough to provide -lpython. Also -L was needed. I.e.

g++ -I/usr/include/python3.5 hw.cpp -L/usr/lib/python3.5/config-3.5m-x86_64-linux-gnu -lpython3.5

And yes. Order matters.
