Compiling Qt5 (5.0.1 & 5.0.2) in Release mode results WebKit linking errors



  • Hi all :)

    I'm trying to build Qt5 (5.0.1 & 5.0.2) in release mode and the build breaks when building QWebProcess with the following error[1]:
    ld: library not found for -lQt5WebKitWidgets

    I see it is the same problem as described in this post:
    https://qtforum.de/forum/viewtopic.php?f=3&t=15672 - however there is no solution there.

    The build works when compiling Qt5 with -debug_and_release, but it seems that the Debug libraries get mixed up with the release libraries, as when I compile and run my program on release mode, I get the following output on QtCreator:

    On Mac OS X, you might be loading two sets of Qt binaries into the same process. Check that all plugins are compiled against the right Qt binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of binaries are being loaded.

    I did export the DYLD_PRINT_LIBRARIES=1 variable, and indeed the debug libraries get mixed, that's why I'm trying to compile on release mode.

    Thanks in avance,
    Jaya

    edit:
    I think I understand what is going on, it builds the library with the name libQtWebKitWidgets and looks for the libQt5WebKitWidgets (note the 5 after Qt). Since I think this is a bug, I created an issue for it: https://bugreports.qt-project.org/browse/QTBUG-30466
