Python.h: No such file or directory

Question

I recently installed KDevelop 4 for C++ development on my Macbook Pro running Ubuntu 12.04 LTS.

I want to embed Python application in my C++ code. To do that, one ne

Answer 1

You want to include the following on the compile line:

`python-config --cflags`

and this on the link line:

`python-config --ldflags`

Answer 2

In your CMakeLists.txt, try adding the following:

find_package(PythonLibs REQUIRED)
include_directories(${PYTHON_INCLUDE_DIRS})
target_link_libraries(<your exe or lib> ${PYTHON_LIBRARIES})

For details of the commands, run:

cmake --help-module FindPythonLibs
cmake --help-command find_package
cmake --help-command include_directories
cmake --help-command target_link_libraries

Answer 3

I assume that it is already installed. Find the path with:

find / -iname python.h

and when you have done so, when compiling add

-I python_h_path

Answer 4

Most likely Python.h is not in your build systems' include path. You can find out where your Python.h is by running

dpkg -L python-dev | grep Python.h

This will also verify that the python-dev package actually installed a Python.h.

I don't have a kdevelop here, but most IDEs have a setting somewhere where you can specify the include path used by the build system, and you should be able to add the path where Python.h lies there.

EDIT:

As Nikolai implied, you will also need to add the correct library path for the linking stage. (Output of python-config --ldflags).

Answer 5

sudo apt-get install pythonX.X-dev

For example for 3.8

sudo apt-get install python3.8-dev

Thank you Cristianjs19 for the comment.

Original Answer:

sudo apt-get install python2.7-dev

worked for me on a "Python.h: No such file or directory" issue

Answer 6

For Linux Ubuntu Putty Users try this:

sudo apt-get update
sudo apt-get install python-dev

then compile it

gcc -o check xyz.c -I/usr/include/python2.7/ -lpython2.7

then run it

./check
