[CMake] Problems building VTK on an Intel Mac with Python 2.5

[Jens Thomas]

Hi,

I'm trying to build a universal binary version of VTK on an Intel Mac 
including the Python and Tcl/Tk wrappers (as I require it for an 
application that uses Tkinter).

I'm using a fresh checkout from CVS for VTK, 
cmake-2.4.6-Darwin-universal and a version of python 2.5 that I built 
myself (configuring the code with: --enable-universalsdk).

The build goes fine, building universal objects as requested until it 
tries to build the file libvtkCommonPythonD.5.1.0.dylib

It then falls over with the error:

ld: common symbols not allowed with MH_DYLIB output format with the 
-multi_module option

According to what I found at:

http://gcc.gnu.org/ml/gcc/2005-06/msg00186.html

I was able to fix this by cutting and pasting the line that was used to 
make the object and appending "-single_module" to the flags passed to 
the linker. I then re-ran make, but I now keep hitting the error:

[  6%] Built target vtkCommonPythonD
make -f Common/CMakeFiles/vtkCommonPython.dir/build.make 
Common/CMakeFiles/vtkCommonPython.dir/depend
make[2]: Nothing to be done for 
`Common/CMakeFiles/vtkCommonPython.dir/depend'.
make -f Common/CMakeFiles/vtkCommonPython.dir/build.make 
Common/CMakeFiles/vtkCommonPython.dir/build
make[2]: *** No rule to make target `bin/libvtkCommonPythonD.dylib', 
needed by `bin/libvtkCommonPython.so'.  Stop.
make[1]: *** [Common/CMakeFiles/vtkCommonPython.dir/all] Error 2
make: *** [all] Error 2

The same build (i.e. same VTK source code and CMake binary) works fine 
when building against the Framework Python (2.3) supplied with the Mac.

I'm usually o.k at debugging Makefiles, but CMake is a bit beyond me and 
I can't work out how to satisfy the dependency. The Makefile where the 
error occurs, appears to differ (substantially) only in that the failing 
one has the additional dependancy:

bin/libvtkCommonPython.so: 
/Users/jmht/ccp1gui_app/python2.5/lib/python2.5/config/libpython2.5.a

but I'm not sure how to follow this up.

I'd be most grateful if anyone has any suggestions as to how I can go 
about fixing this.

Best wishes,

Jens
