boost +python25 links with system python libs (instead of macport libs)

[evert.rol@…]

The ${prefix}/lib/libboost_python-mt.dylib (& related) library has a dependency on the system python library, not on the python2.5 installed by macports (obviously only when installing boost with port install boost +python25). This can be seen using eg:

$> otool -L lib/libboost_python-mt.dylib 

lib/libboost_python-mt.dylib:

	/opt/local/lib/libboost_python-mt.dylib (compatibility version 0.0.0, current version 0.0.0)

	/System/Library/Frameworks/Python.framework/Versions/2.5/Python (compatibility version 2.5.0, current version 2.5.1)

	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.4.0)

	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.0.0)

The problem only really shows up when compiling a source to a .so module with boost-python: the macports python2.5 complains when importing the module: "Fatal Python error: Interpreter not initialized (version mismatch?)", while the system python does not show this error.

(Note that printing sys.path in macports python2.5 does not show any standard system path, only the macports one, as it should.)

The problem does not exist for the python 2.6 (probably since there are no system libraries for this version).

Could be related to the LINKFORSHARED issue, see #15099.

[evert.rol@…]

Ticket can now be closed: the origin of the problem is probably in an incorrect python2.5 installation, see #17998.

Could have just modified this ticket... oh well.

Temporary workaround (for now can be implemented in post-build phase):

install_name_tool -change /System/Library/Frameworks/Python.framework/Versions/2.5/Python /opt/local/Library/Frameworks/Python.framework/Versions/2.5/Python libboost_python-mt.dylib

And don't forget about libboost_python.dylib, when installing with +st variant

so does this mean if i want the libboost-python.dylib then i need to install the boost port as follows; sudo port install boost+python26

i previously just installed boost ,e.g : sudo port install boost

if i do that then it does not generate the libboost-python.dylib

please let me know
