Re: [boost] Help with Access Violation in simple serialization

I am linking to the following libs in my project:

glut32.lib glu32.lib opengl32.lib odbc32.lib odbccp32.lib cv.lib cxcore.lib
highgui.lib

basically OpenGL and OpenCV.

Are there any imcompatibility issues? I simply CANNOT instantiate an output
file!!!.

Thanks in advance,

Tiago
