I am cross compiling opencv-2.4.10 with GTK+2.0. while doing cmake, I have enabled GTK using the below command

cmake -DWITH_GTK=ON -DCMAKE_TOOLCHAIN_FILE=../linux/arm-gnueabi.toolchain.cmake ../..

But still It is showing like this

-- GUI: -- QT: NO -- GTK+ 2.x: NO -- GThread : NO -- GtkGlExt: NO -- OpenGL support: NO -- VTK support: NO

Below is my arm-gnueabi.toolchain.cmake file,

set(CMAKE_SYSTEM_NAME Linux) set(CMAKE_SYSTEM_VERSION 1) set(CMAKE_SYSTEM_PROCESSOR arm)

can any one suggest how to resolve?
