[osg-users] PNG Library Crashing - 32 vs 64 bit mismatch possible

[Dave Sargrad]

Hi,

I've been struggling to get the PNG plugin working. I've built it, but the cookbook_02_7 is crashing down inside libpng16.dll.


I have a couple of questions.
1] I would have thought that I am doing a 64-bit build, since I have a 64-bit OS. However when I run cmake/configure I see it report 32-bit architecture detected.

So I have been pointing my cookbooks (osgrecipes) to the x86 versions found in the 3rdParty folder: example C:/osg/OpenSceneGraph-3.2.2-rc2/3rdParty/x86/lib/libpng16.lib is the value I have set PNG_LIBRARY to.

The current callstack I see when I crash is as follows:

Any suggestions would be appreciated.
