PythonQt and Anaconda Python

Question

I am trying to build PythonQt against anaconda python (2.7.x). Running the included PyGuiExample I am unable to get any Python other than the system install.

Running OS X 10.10, Qt 5.5, latest Anaconda.

I have set the python.prf as

PYTHON_CONFIG_PATH = /Users/me/anaconda/bin/python-config
QMAKE_CXXFLAGS += $$system($${PYTHON_CONFIG_PATH} --includes)
LIBS += $$system($${PYTHON_CONFIG_PATH} --libs)

Two environment variables have been set

PYTHON_PATH /Users/me/anaconda/include/python2.7
PYTHON_LIB /Users/me/anaconda/lib

The build (in QtCreator) is successful with a high number of warnings about unused parameters.

Any thoughts on getting PythonQt built against a Python installation other than the system framework?

In the python.prf file you have the macx portion. You probably changed the unix part which is not take into account.

You should just change the lines:

INCLUDEPATH += /usr/local/Frameworks/Python.framework/Headers
LIBS += -F/usr/local/Frameworks -framework Python

This is what I did to use the brew version of python and it worked pretty well.

as result I get all the libraries in the lib folder and here is the linked python lib (otool -L libPythonQt.dylib):
