Re: [Plplot-general] Text plotting

[Werner S. <sm...@ia...>]

Hi Hans,

How did you configure the wxWidgets library? from the makefile it  
seems that you use wxX11 and maybe even the "universal" build. This is  
not recommended at all, since the wxX11 is rather not much supported,  
so it may work for you or not. In this case it seems it doesn't work  
for you. It's much better to use the wxGTK port of wxWidgets, since  
this port is actively worked on, feature complete and looks fine. Bad  
thing is, that you need the gtk libraries installed (and the gtk  
developer files on the developer machine), but this is actually always  
the case, even on KDE machines.

If you are using wxX11, and there is no problem using gtk (RHEL 4 has  
surely decent gtk support), then I would strongly suggest to use  
wxGTK. And don't use the universal build, since I also doubt if that  
works for the wxWidgets driver, at least I never have tested this.

HTH,
Werner
