Just happened on this thread and it raised some questions for me.
1) I read that the gcc version on MOS does not support templates and other C++ functions properly, is that true? Some code I use is very heavily templated
Was there any communication from the MOS team telling this support will be integrated?
2) Sounds like a lot of people are willing to help make the wrapper, I doubt the wxwidgets team itself will have time for it. But it is an open source effort, I have no doubt they would welcome an effort.
And finally a remark. Yes of course it is nicer if apps are written in MUI, but for many cross platform developers having to do that just means there will be no MOS port at all. If it would just be a matter of putting the crosscompiler to a MOS target they might be much more inclined to do ports for MOS and the platforms viability would rise enormously.
