[ros-users] rosinstall Cturtle installation error on Snow leopard

Mon Aug 30 21:17:10 UTC 2010

Ken, 

Do you (or does anyone else) know a good way to get wxWidgets (plus wxPython) working well on Snow Leopard? 

According to the wxWidgets site, wxWidgets 2.9.1 is fairly stable and Snow Leopard friendly: http://www.wxwidgets.org/

However, according to the wxPython site, they are only on 2.8.11: http://www.wxpython.org/

Do you know if this causes any problems? Is the older wxPython wrapper compatible with the newer wxWidgets core?
