Include Python in Qt Creator

Question

I am trying to embed python in my c++ code in my qt project as per this tutorial. I am now getting this error code: "error: undefined reference to `_imp__Py_Initialize'"

Before this, I had the same problem in CodeBlocks and fixed it by with these additional arguments "-IC:\Python27\include\ -IC:\Python27\libs\" and "C:\Python27\libs\python27.lib"

Adding the same commands to my .pro file as such:

QMAKE_CXXFLAGS += -Wall -fexceptions -g -IC:\Python27\include\ -IC:\Python27\libs\ C:\Python27\libs\python27.lib

Allows me to import python.h but nothing more.

I know that questions like this have been posted before, and they helped me get running in CodeBlocks, but the same information dosent apply to Qt, or I am implementing it wrong.

You should use LIBS configuration variable to add an external library to your project. Something like this:

LIBS += C:\Python27\libs\python27.lib

You can find more info in documentation.

I'm afraid that this does not help, the error still persists.

I'm sorry, -L prefix was wrong. It's used for adding a new library path.

To build on HeyYO's answer, the .pro arguments to fix the problem are:

INCLUDEPATH = c:\Python27\include\ c:\Python27\libs\

LIBS += C:\Python27\libs\python27.lib

QMAKE_CXXFLAGS += C:\Python27\libs\python27.lib
