OpenCV: highgui library not implemented



  • Hi,

    Qt/OpenCV runs OK on my laptop, most features also on my android but...
    I'm stuck when exporting on Android with highgui functions.
    I have OSX 10.7,Qt 5.3.1 and openCV4Android 2.4.9 (already compiled version)

    When I try to use the highgui library, I get a nice "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, ..."
    In OpenCV source, it says I need Cocoa or Carbon.
    Since I'm using OSX, both should be there.

    Someone has a clue please?
    Thanks a lot,
    Michaël

    Hi and welcome to devnet,

    Cocoa/Carbon are for OS X build of OpenCV, you are using an android build. You should rather ask this question on the OpenCV forums



  • OK, thanks Sgaist.
    Done.
    If I get an answer, I'll post it.
