fatal error: Python.h: No such file or directory

by

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.

Looks like you haven’t properly installed the header files and static libraries for python dev. Use your package manager to install them system-wide.

For apt (Ubuntu, Debian…):

sudo apt-get install python-dev   # for python2.x installs
sudo apt-get install python3-dev  # for python3.x installs

For yum (CentOS, RHEL…):

sudo yum install python-devel    # for python2.x installs
sudo yum install python3-devel   # for python3.x installs

For dnf (Fedora…):

sudo dnf install python2-devel  # for python2.x installs
sudo dnf install python3-devel  # for python3.x installs

For zypper (openSUSE…):

sudo zypper in python-devel   # for python2.x installs
sudo zypper in python3-devel  # for python3.x installs

For apk (Alpine…):

# This is a departure from the normal Alpine naming
# scheme, which uses py2- and py3- prefixes
sudo apk add python2-dev  # for python2.x installs
sudo apk add python3-dev  # for python3.x installs

For apt-cyg (Cygwin…):

apt-cyg install python-devel   # for python2.x installs
apt-cyg install python3-devel  # for python3.x installs
