Hi guys I am not an expert I have an problem with the cross-compilation of opencv for ARM.
My problem is that when I build the libraries with the Cmake it finish propertly but this is the output:
GUI:
-- QT 4.x: NO
-- GTK+ 2.x: NO
-- GThread : NO
-- GtkGlExt: NO
-- OpenGL support: NO
--
-- Media I/O:
-- ZLib: build (ver 1.2.7)
-- JPEG: build (ver 62)
-- PNG: build (ver 1.5.12)
-- TIFF: build (ver 42 - 4.0.2)
-- JPEG 2000: build (ver 1.900.1)
-- OpenEXR: build (ver 1.7.1)
--
-- Video I/O:
-- DC1394 1.x: NO
-- DC1394 2.x: NO
-- FFMPEG: NO
-- codec: NO
-- format: NO
-- util: NO
-- swscale: NO
-- gentoo-style: YES
The opencv libraries are build good, but the GTK for example it seems that is not build. Anyways I tried to compile my .cpp file which use the opencv libraries, I compile it like this:
arm-linux-g++ -static -o exampleWindows IPCamera.cpp `pkg-config --cflags --libs opencv`
It compile without problem and I get the executable in ARM format, and with staic linker(as I want), but when I try to run in my ARM I get this error:
OpenCV Error: Unspecified error (The function is not implemented.
Rebuild the library with Windows, GTK+ 2.x or Carbon support.
If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config,
then re-run cmake or configure script) in cvNamedWindow,
file /home/jesus/opencv/opencv/modules/highgui/src/window.cpp, line 483
terminate called after throwing an instance of 'cv::Exception'
what(): /home/jesus/opencv/opencv/modules/highgui/src/window.cpp:483: error: (-2)
The function is not implemented.
So obviously I need to build the Cmake with this library but I do not know if I have to indicate the PATH for indicate where are this library in my PC when I build the CMake.
This is my command for build the CMake:
cmake -D SOFTFP=ON -D BUILD_SHARED_LIBS=OFF -D CMAKE_BUILD_TYPE=DEBUG -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D OPENCV_BUILD_3RDPARTY_LIBS=ON -D WITH_FFMPEG=ON -D WITH_GTK=ON -D WITH_OPENEXR=ON -D WITH_OPENNI=ON -D WITH_PNG=ON -D WITH_TBB=ON -D WITH_XINE=ON -D WITH_GSTREAMER=ON -D CMAKE_TOOLCHAIN_FILE=../opencv/platforms/linux/arm-gnueabi.toolchain.cmake ../opencv
Thank you so much.
