I compile one test code with g++ without any issue.
#include \"Python.h\"
int main(int argc, char** argv)
{
Py
Take a look at Lucas's comment for the answer:
"To get rid of the _POSIX_C_SOURCE warning, make sure to include Python.h before all other header files."
I had the same problem. I use Boost Python, so for me I moved the include of boost/python.hpp to the first line in my .cpp file.
