fatal error Python h No such file or directory

Question

I am trying to build a shared library using a C extension file but first I have to generate the output file using the command below:

gcc -Wall utilsmodule.c -o Utilc

After executing the command, I get this error message:

> utilsmodule.c:1:20: fatal error: Python.h: No such file or directory
compilation terminated.

I have tried all the suggested solutions over the internet but the problem still exists. I have no problem with Python.h. I managed to locate the file on my machine.

On Ubuntu, I was running Python 3 and I had to install

sudo apt-get install python3-dev

If you want to use a version of Python that is not linked to python3, install the associated python3.x-dev package. For example:

sudo apt-get install python3.5-dev
