[mapserver-dev] Possible bug to be reported ?

[Seth G]

Hi Bruno,

I've got Python building with SWIG 4.0.1 - see the pull request at https://github.com/mapserver/mapserver/pull/5983
I've not tested Perl or PHP so any feedback on these welcome.
The Python issues are documented at https://github.com/mapserver/mapserver/issues/5982
Let me know how you get on,

Seth
