linking to ogre corrupts pngs
Posted: 2011-10-27T03:46:36-07:00
I have a simple program:
I can compile it fine with:
But when i run it i get "corrupt image `world.200408.3x5400x2700.png' @ error/png.c/ReadPNGImage/3101"
If i remove the link to OgreMain, it runs fine. Any idea what might be causing this?
Im running Ubuntu 10.10 with Magick++ 6.6.2 and Ogre 1.7.3 from the ogre team ppa.
UPDATE:
After running ldd on both libMagick++.so and libOgreMain.so, i noticed that ogre links to libfreeimage as well as a few other libs that magick doesnt use. It seems like linking to freeimage is what is causing the problems.
I still dont know how to fix this though 
Code: Select all
#include <Magick++.h>
int main(int argc, char *argv[])
{
Magick::Image in;
in.read("world.200408.3x5400x2700.png");
return 0;
}
