[Solved-2 Solutions] fatal error: Python.h: No such file or directory
Error Description:
- When we try to build a shared library using a C extension file but first we have to generate the output file using the command below:
gcc -Wall utilsmodule.c -o Utilc click below button to copy the code. By - python tutorial - team
- After executing the command, we get this error message:
utilsmodule.c:1:20: fatal error: Python.h: No such file or directory compilation terminated.
Solution 1:
- We need to use our 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 click below button to copy the code. By - python tutorial - team
For yum (CentOS, RHEL...):
sudo yum install python-devel click below button to copy the code. By - python tutorial - team
For dnf (Fedora...):
sudo dnf install python2-devel # for python2.x installs
sudo dnf install python3-devel # for python3.x installs click below button to copy the code. By - python tutorial - team
Solution 2:
- Make sure that the Python dev files come with your OS.
- We should not hard code the library and include paths. Instead, we can use pkg-config, which will output the correct options for our specific system:
$ pkg-config --cflags --libs python2
-I/usr/include/python2.7 -lpython2.7 click below button to copy the code. By - python tutorial - team
- We may add it to your gcc line:
gcc $(pkg-config --cflags --libs python2) -Wall utilsmodule.c -o Utilc
