Bug 13520 – qmake/gmake sometimes has trouble properly resolving dependencies

• Component: Tools / Tests
• Status: RESOLVED INVALID

[Alexander Botero-Lowry]

Sometimes, if I rebuild the QT port without cleaning up the build dir I will get a failed build since not all the dependencies have been correctly noticed and recompiled (I've also seen this where after editing a file I had to delete the object file or it wouldn't be recompiled).

An example of this might go something like:
 c++ -pthread -Wl,-rpath,/usr/home/alex/WebKit/WebKitBuild/Release/lib -o QtLauncher main.o    -L/usr/local/lib -L/usr/home/alex/WebKit/WebKitBuild/Release/lib -lWebKitQt -lQtGui -L/usr/ports/x11-toolkits/qt4-gui/work/qt-x11-opensource-src-4.2.2/lib -L/usr/local/lib -L/usr/X11R6/lib -lpng -L/usr/ports/devel/qt4-corelib/work/qt-x11-opensource-src-4.2.2/lib -lXi -lXrender -lXrandr -lXfixes -lXcursor -lXinerama -lfreetype -lfontconfig -lXext -lX11 -lQtCore -lz -lm -lglib-2.0 -liconv

As a workaround you can define the WEBKIT_FULLBUILD environment variable before running build-webkit.  This will force a clean build.

I've seen the same thing. I'm having trouble rebuilding the qtlauncher. I don't want to do a clean build if all I changed was the qt launcher. Deleting the main.o for the QtLauncher didn't even solve that one.

Closing this since the Qt port is not part of the tree any longer.
