QtCreate 2.3.0 and Opencv 2.3.0 installation

[MohdRash]

Hello all




i'm a new to qt, i used to use opencv with microsoft visual studio 2010 express edition without any problems

but when decided to swtich to Qt i faced a common problem of installing and linking opencv with qt ..
i've read many and many posts for suggested solutions , but most of them confused me up .. that's maybe usually because i'm not keen to compiler types and
other stuff related to it like buidling libraries and using cmake

however ,, i need a simple and precise explanation for installing opencv with qt plz..

Hi Mohd,

I followed this tutorial:
http://knowtheabc.wordpress.com/2011...nd-qt-creator/
and
http://knowtheabc.wordpress.com/2011.../opencv-in-qt/

he uses OpenCV 2.2, but it is the same as 2.3.

When debugging, if you have problems just ask.

Hello danilodsp

thank you for helping me .. when i try to compile opencv 2.3 libraries using cmake 2.8 or 2.6 it tills me that
----------------
CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
