Relative paths getting turned into absolute in project file -- new "feature" in Qt 5.5?

poorchef

Hello, I am new to the forum here. Sorry for the long details here, but they are relevant. I'm passing the following command to create a project file:

INSTALL_DIR=/usr/gapps/asciviz/blockbuster/dev/chaos_5_x86_64_ib /usr/local/tools/qt-5.5.1/bin/qmake -project -d -d -d -nopwd -Wall 'LIBS += /usr/gapps/asciviz/blockbuster/dev/chaos_5_x86_64_ib/lib/libboost_thread.a -lXtst -lXinerama   -lsmovie  -lsrwpng -ljpeg -llzo2 -lz -llzma -lm  ' "INCLUDEPATH += libdmx ../common ../RC_cpp_lib ../config /usr/gapps/asciviz/blockbuster/dev/chaos_5_x86_64_ib/include  $(echo -I/usr/X11R6/include -I/usr/X11/include -I/usr/X11R6/include -I/usr/X11/include  | sed -e s/-I//g ) " "MAKEFILE = Makefile.qt.include" "DEFINES +=  NO_BOOST USE_MPI=1 USE_STDARG HAVE_STDLIB_H=1 HAVE_STRING_H=1 HAVE_UNISTD_H=1 HAVE_STDARG_H=1 USE_STDARG=1 MALLOC_RET_VOID=1  USE_DMX USE_QT " "QT += network"  "QT += opengl" "HEADERS = errmsg.h events.h   ImageCache.h ../RC_cpp_lib/stringutil.h ../RC_cpp_lib/timer.h ../config/version.h MovieCues.h errmsg.h pure_C.h util.h blockbuster_qt.h sgi-rgbFrame.h convert.h smFrame.h ../RC_cpp_lib/pathutil.h pngFrame.h splash.h pnmFrame.h tiffFrame.h ../RC_cpp_lib/Prefs.h Renderer.h glRenderer.h dmxRenderer.h " "FORMS += MovieCueWidget.ui BlockbusterControl.ui InfoWindow.ui" ""  "RESOURCES += images.qrc"  ./main.cpp blockbuster_qt.cpp movie.cpp timer.C pure_C.c frames.cpp  slave.cpp cache.cpp  common.cpp Prefs.C sgi-rgbFrame.cpp convert.cpp smFrame.cpp pngFrame.cpp splash.cpp pnmFrame.cpp tiffFrame.cpp libdmx/dmx.c MovieCues.cpp events.cpp ImageCache.cpp Renderer.cpp util.cpp settings.cpp errmsg.cpp Renderer.cpp x11Renderer.cpp glRenderer.cpp dmxRenderer.cpp

When the command completes, in Qt 5.1.x and earlier, I get the following line in my blockbuster.pro file:, which is correct.

SOURCES += blockbuster_qt.cpp \
           cache.cpp \
           common.cpp \
           convert.cpp \
           dmxRenderer.cpp \
           errmsg.cpp \
           events.cpp \
           frames.cpp \
           glRenderer.cpp \
           gprof-helper.c \
           ImageCache.cpp \
           iotest.C \
           main.cpp \
           movie.cpp \
           MovieCues.cpp \
           newcache.cpp \
           pngFrame.cpp \
           pnmFrame.cpp \
           Prefs.C \
           pure_C.c \
           qrc_images.cpp \
           Renderer.cpp \
           settings.cpp \
           sgi-rgbFrame.cpp \
           SidecarServer.cpp \
           slave.cpp \
           smFrame.cpp \
           splash.cpp \
           tiffFrame.cpp \
           timer.C \
           util.cpp \
           x11Renderer.cpp

But in Qt 5.5, I get this:

SOURCES += /main.cpp \
           /blockbuster_qt.cpp \
           /movie.cpp \
           /timer.C \

           /common.cpp \
           /Prefs.C \
           /sgi-rgbFrame.cpp \
           /convert.cpp \
           /smFrame.cpp \
           /pngFrame.cpp \
           /splash.cpp \
           /pnmFrame.cpp \
           /tiffFrame.cpp \
           /libdmx/dmx.c \
           /MovieCues.cpp \
           /events.cpp \
           /ImageCache.cpp \
           /Renderer.cpp \
           /util.cpp \
           /settings.cpp \
           /errmsg.cpp \
           /x11Renderer.cpp \
           /glRenderer.cpp \
           /dmxRenderer.cpp \
           common.cpp \
           blockbuster_qt.cpp \
           events.cpp \
           errmsg.cpp \
           settings.cpp \
           movie.cpp \
           frames.cpp \
           slave.cpp \
           util.cpp \
           SidecarServer.cpp \
           smFrame.cpp \
           splash.cpp \
           glRenderer.cpp \
           x11Renderer.cpp \
           dmxRenderer.cpp \
           pnmFrame.cpp \
           pngFrame.cpp \
           tiffFrame.cpp \
           sgi-rgbFrame.cpp \
           cache.cpp \
           convert.cpp \
           ImageCache.cpp \
           Renderer.cpp

The generation of sources with a slash prepended, e.g., "/blockbuster_qt.cpp" etc. causes errors like this when I run make.

make[3]: *** No rule to make target `/blockbuster_qt.cpp', needed by `blockbuster_qt.o'.  Stop.

Is this intentional new behavior? It prevents me from upgrading to Qt 5.5 because I just cannot seem to stop this behavior.

Thanks.

Hi and welcome to devnet,

Looks strange, could you test that again with Qt 5.6 beta ?

poorchef

@SGaist Thanks, I'll check that out. I can confirm that version 5.4.2 works with this command. It's just 5.5.1 that is breaking so far for me.

@poorchef Unfortunately, I cannot build Qt 5.6 on our clusters. I get the following error:

No need to built it yourself, there are now the pre-built package for the beta.

In any case, I've could reproduce this locally. You can check the bug report system to see if it's something known. If not please consider opening a new report providing as much details as you can to reproduce this. Providing a minimal example that helps reproduce this would be a big plus.
