Re: [Plplot-general] unable to load wxwidgets driver

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

Hi,

another thing which came into my mind is, that you forgot to copy the 
wxwidgets library, since the wxwidgets driver obviously depends on it - 
but this is even more problematic, since the wxwidgets library depends 
on many other system libraries. But you can always check with the 
command "ldd" if there is any dependency on a library which is not 
fulfilled.

HTH,
