[mapserver-dev] Python 3 classes missing

[Schindler, Fabian]

Hi Seth,

To clarify: I used the packaged version, where I experienced the issue,
then tried to build the package myself and had the same issue. There is no
CMake involved, it seems like the compiled SWIG files are linked to the
systems mapserver-devel package. The source just seems to be the Python
part of mapscript and does not include source code of the core mapserver.

Thanks for the response,
Fabian
