I have compiled opencv on snow leopard and it says it compiled correctly, however when I try to compile my sample program against it, I get output like:
g++ -o tm_scons template.o -L/opencv/opencv/build/lib -lcxcore -lcv -lcvaux -lhighgui -lml
ld: warning: in /opencv/opencv/build/lib/libcxcore.dylib, file is not of required architecture
ld: warning: in /opencv/opencv/build/lib/libcv.dylib, file is not of required architecture
ld: warning: in /opencv/opencv/build/lib/libcvaux.dylib, file is not of required architecture
ld: warning: in /opencv/opencv/build/lib/libhighgui.dylib, file is not of required architecture
ld: warning: in /opencv/opencv/build/lib/libml.dylib, file is not of required architecture
Is this likely a problem with my compilation of OpenCV or of my app that is using it?
As it turns out the magic was using -m32 and switching to the /usr/bin/g++-4.0 compiler.
Ugh….
