Qt RC_FILE vs automatic resource file conflict


  • 0 down vote favorite

    Trying to add an app icon to Qt application. Simple solution for Qt 5.1 and higher is to use
    @RC_ICONS += app.ico @

    This doesn't work for earlier versions, so one has to include *.rc file with
    @IDI_ICON1 ICON DISCARDABLE "app.ico"@

    However this breaks another Qt functionality concerning resource files, for example adding application version with VERSION variable.

    When just VERSION variable is used, there is _resource.res file generated automatically during build (rcc is involved):

    @rc -DUNICODE -DWIN32 -DAPP_VERSION="0.1.1" -DQT_DLL -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DNDEBUG -fo release\QUSBAD_resource.res QUSBAD_resource.rc@

    After I add RC_FILE += ico.rc, rcc invoke is the same except rc and res files names, but resulting application doesn't have any version information.

    @rc -DUNICODE -DWIN32 -DAPP_VERSION="0.1.1" -DQT_DLL -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DNDEBUG -fo release\ico.res ..\QUSBAD\ico.rc@

    Is there a way to incorporate both automatic and custom rc-files?

    Hi,

    To workaround that, you can test what the current version of Qt is in your pro file and use one technique or the other.

    However, it might be considered a regression. You should check the "bug report system":http://bugreports.qt-project.org to see if it's something known. If not, please consider opening a new report providing a minimal compilable example showing how to reproduce this behavior.

  • The only workaround I currently happened to get is to first run qmake to create auto-generated *.rc file in build folder, then insert IDI_ICON1 line there and build.
