    Default Qt designer plugin errors on OSX Leopard

    Hi everybody

    I'm new here so please forgive me if I'll do some nonsenses. I have question regarding Qt4 (4.3.3) designer plugins.

    I've compiled and installed Qt4 from source into /usr/qt4 directory successfully. I've tested installation with building an application which I've developed on another machine some time ago. And it worked perfectly, so I figured Qt installation is OK.

    Now when I compile QScintilla plugin or qwt plugin for designer I get in Designer->About plugin next info:
    The file /usr/qt4/plugins/designer/libqscintillaplugin.dylib is not a valid Qt4 plugin
    and for qwt
    The file '/usr/qt4/plugins/designer/libqwt_designer_plugin.dylib' is not a valid Qt plugin.

    Both projects are compiled without any problem.

    Any suggestions?
    Best regards

    What did you do exactly to build those plugins?

    Well,

    I've compiled sources as described.

    qmake project.pro (for qscintilla = qscintilla.pro and for designer plugin designer.pro)
    make
    sudo make install

    (I have set QMAKESPEC=macx-g++; QTDIR=/usr/qt4 and set PATH accordingly)

    At first I thought it is QScintilla then I downloaded qwt source and tried again. With both I had successful compilation without errors.

    Also I already had successful installation in Tiger. So is it Leopard?

    g++ -v returns:
    Using built-in specs.

    Do you get different messages for those plugins? Or did you just made a mistake while rewriting the error message?

    No messages are the same for all NEW plugins. Plugins build during Qt installation (bundeled with Qt) are normally loaded. For example libworldtimeclockplugin.dylib is loaded without any problems...

    It's tricky .... I'll investigate further

    Anyway thanks for your interest and help, I hope together we'll crack this one...

    What does "ldd <pluginfile>" return on your plugins and plugin bundled with Qt?

    What about the same (skip nm, only ldd/otool is important) for a working plugin?

    Ok no problem (during these days I've recompiled Qt ad put it in /Developer/Qt4 ... just for info)

    here is comparison:

    Honestly I don't see anything that could be wrong. You can take a look at .pro files used to build both plugins and try to find the difference. Maybe something did change in one of the recent versions of the system.
