I tried to compile without QtDesigner (i compile the semples given with OpenCV) i use this script :
for i in *.cpp; do
echo "compilling...$i"
g++ -ggdb `pkg-config --cflags opencv` -o `basename $i .cpp` $i `pkg-config --libs opencv`;
done
and its work normaly !!!! what should i do to success the compilation with QtDesigner ?
HELLO ;)
Hi,
You are compiling all your cpp files, but designer makes some other files.
Have you tryied to use "qmake" as described into qt manuals? Probably you will have to edit the ".pro" file to adapt it to use the OpenCV libs.
