Im compiling the example with MinGw 32 using msys

I got the compiling stage all right

But then, when i try to link i got errors complaining about the methods
that are supposedly in liblob.a :

>g++ -g`wx-config --cflags`   extractBlob.o parser.o getBackground.o
kalman.o condensation.o execute.o main.o -o videotracker.exe -lcxcore
 -lcv -lhighgui -lcvaux -lml `wx-config --libs` -lblob 

the linker screams:
extractBlob.o: In function

and so on, like there was no a -L. -lblob in the linking command

Maybe this is not a windows libblob.a file but a linux one?

Best regards

yes, sorry you are right. The libblob.a, as you can see from the ".a" 
extension, is a
linux static library. You must go to OpenCv yahoo groups and checkout the 
library and
then  rebuildd it under win.

Regards,
