Tim,
Thanks for the suggestion, I really appreciate your help.
I added the code below to my *.pro file and it runs now, but with some
errors which I need to look into still.
Added code:
ADD_DEFINITIONS(-DGUI_EXPORT=)
ADD_DEFINITIONS(-DCORE_EXPORT=)
ADD_DEFINITIONS(-DPYTHON_EXPORT=)
I am now getting this message when I try to run it:
QgsCoordinateReferenceSystem::findMatchingProj will only work if prj acr
ellipsoid acr and proj4string are set!...
Layer is valid
QgsCoordinateReferenceSystem::findMatchingProj will only work if prj acr
ellipsoid acr and proj4string are set!...
Some times it runs, sometimes it doesn't after these messages (??).
As a follow-up, do the tutorials need to be compiled against the full source
code or should they work with only the install from the repository? I have
it "working" with the full source code but am wondering if this is
necessary.
Thanks Again,
Matt
