This file describes some things to be aware of when building SIP on MacOS/X
for use with python from Fink (/sw/bin/python) instead of python from Apple
(/usr/bin/python).
In short, try using configure.py with the following options:
/sw/bin/python configure.py -p darwin-g++ INCDIR_QT=/sw/include/qt \
LFLAGS_PLUGIN="-bundle -flat_namespace -undefined suppress"
In detail, three problems are addressed:
1) Error message from configure.py:
Error: /sw/share/qt3/mkspecs/darwin-g++/qmake.conf: macro
'QMAKE_LIBDIR/$(TARGET1)' is not defined.
The solution is to give the following option to configure.py:
-p darwin-g++
Alternatively, "macx-g++" may work also.
2) Error message from configure.py:
This is SIP 4.0.1 for Python 2.3.3 on darwin.
Error: qglobal.h could not be found in /sw/include.
The solution is to give the following option to configure.py
INCDIR_QT=/sw/include/qt
2) Linking problem where "make" completes without error, but the sip library
does not correctly import into python.
One symptom is that if PyQt has been built, "import qt" results in:
Python Fatal Error, interpreter not initialized (version mismatch?)
Abort trap
(Since building PyQt can be slow, it is best to test SIP first before building
PyQt.) To test the SIP python library:
cd siplib
/sw/bin/python
>>> import sip
If a "bus error" error occurs (perhaps after a few seconds), then the problem
may be that SIP not linked properly for the version of python in /sw/bin.
Find the correct linking options:
/sw/bin/python
>>> import distutils.sysconfig
>>> distutils.sysconfig.get_config_var('LDSHARED')
'gcc -L/sw/lib -bundle -flat_namespace -undefined suppress'
The solution is to give the following option to configure.py
LFLAGS_PLUGIN="-bundle -flat_namespace -undefined suppress"
These solutions are for Mac OS X Version 10.3.4, sip-4.0.1, PyQt-mac-gpl-3.12,
and python 2.3.3 from Fink (/sw/bin/python, not /usr/bin/python), Fink 0.7.0.
