[wx-dev] wxGLCanvas

[Peter Marino]

hi wx-user & Stefan,

Thanks for the point in the right direction. I have changed the order, 
was a little difficult because I was using kdevelop build options and 
automake-manager to setup the libraries and getting them to play 
together was almost impossible.

I decided to write it in the Makefile.am as:
Hole_LDFLAGS=$(top_builddir)/SigmaWindow/libSigmaWindow.a \
`$(top_srcdir)/Linux/wxWidgets/build-debug/wx-config --static --libs 
gl,core,base`

and this seems to work, which is great. Only need to find out how to 
make it change wx builds depending on which configuration I use in 
kdevelop (i.e. debug, release, other )

regards,
Peter
