[wxVTK] wxVTK build issues

[<Tom...@se...>]

Hi all,

  i want to ask few questions about building wxVTK. If there is some sort of faq
i have not found, please tell me.

1. when running cmake, i get complaints about missing PkgConfig. Does that mean
pkg-config? Because i have that one.

CMake Error: PkgConfig_DIR is not set.  It must be set to the directory containing PkgConfigConfig.cmake in order to use PkgConfig.

Found in the list that i should switch the comments in CMakeLists.txt, so i did, well
after all there is the comment about cmake version 2.4.6 which is newer than i have.

2. But then i get build errors:

/usr/bin/c++   -Wno-deprecated -I/usr/lib/wx/include/gtk2-unicode-release-2.6 -I/usr/include/wx-2.6       -I/usr/bin/../include/vtk-5.0 -I/usr/include/tcl8.4 -I/usr/include/python2.4 -I/usr/include/freetype2 -isystem /usr/lib/wx/include/gtk2-unicode-release-2.6 -isystem /usr/include/wx-2.6 -I/home/baf/tks/pok/wxVTK/src   -DGTK_NO_CHECK_CASTS -D__WXGTK__ -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D_LARGEFILE_SOURCE=1 -DNO_GCC_PRAGMA -o CMakeFiles/wxImagePlaneWidget.dir/src/wxVTKRenderWindowInteractor.o -c /home/baf/tks/pok/wxVTK/src/wxVTKRenderWindowInteractor.cxx

/usr/include/wx-2.6/wx/gtk/win_gtk.h:68: error: 'GdkVisibilityState' does not name a type

Apparently, the gdk include directory is not on path but why shouldnt the lines
CMakeLists.txt:39 and CMakeLists.txt:59 add these?

I took Modules/FindGTK2.cmake and manually included it in CMakeLists.txt changing
where pkg-config is looked for and several other things and got to linking.

3. Then it tries to link with 64-bit libraries which are not on my system. (I suppose this
is more a cmake error, am i right?):

/usr/bin/c++   -Wno-deprecated -I/usr/lib/wx/include/gtk2-unicode-release-2.6 -I/usr/include/wx-2.6       -I/usr/bin/../include/vtk-5.0 -I/usr/include/tcl8.4 -I/usr/include/python2.4 -I/usr/include/freetype2 -isystem /usr/lib/wx/include/gtk2-unicode-release-2.6 -isystem /usr/include/wx-2.6 -I/opt/wxVTK/src -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libpng12   -DGTK_NO_CHECK_CASTS -D__WXGTK__ -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D_LARGEFILE_SOURCE=1 -DNO_GCC_PRAGMA -o CMakeFiles/wxImagePlaneWidget.dir/src/wxVTKRenderWindowInteractor.o -c /opt/wxVTK/src/wxVTKRenderWindowInteractor.cxx
make[2]: *** No rule to make target `/usr/lib64/libfreetype.so', needed by `bin/wxImagePlaneWidget'.  Stop.

When i edited all the makefiles changing /usr/lib64/lib*.so for /usr/lib/lib*.so, make
did succeed and everything seems to work well.

I use:
cmake 2.4.5
wx-config 2.6.3
libgtk2.0 2.8.20
vtk 5.0.2
debian lenny

So, finally it works but i am really curious how this is supposed to be done the right
way? Is this 'normal'? Did i miss something? Thanks in advance for any suggestions.
