qmake and gdb

I have just installed openSuSE 13.2. qmake <qt4> generates a Makefile including

$(TARGET): ui_Ledger.h $(OBJECTS)
$(LINK) $(LFLAGS) -o $(TARGET) $(OBJECTS) $(OBJCOMP) $(LIBS)
{ test -n “$(DESTDIR)” && DESTDIR="$(DESTDIR)" || DESTDIR=.; } &&
() test $$(gdb --version | sed -e 's,^0-9]^0-9]([0-9]).([0-9]).*,\1\2,;q’) -gt 72 &&
gdb --nx --batch --quiet -ex ‘set confirm off’ -ex “save gdb-index $$DESTDIR” -ex quit ‘$(TARGET)’ &&
test -f $(TARGET).gdb-index && objcopy --add-section ‘.gdb_index=$(TARGET).gdb-index’
–set-section-flags ‘.gdb_index=readonly’ ‘$(TARGET)’ ‘$(TARGET)’ &&
rm -f $(TARGET).gdb-indGNU gdb (GDB; openSUSE 13.2) 7.8exGNU gdb (GDB; openSUSE 13.2) 7.8 ||
true

The link operation works fine but the test in line (*) fails as ‘gdb --version’ starts with
GNU gdb (GDB; openSUSE 13.2) 7.8
test gets then mixed up with the sed output.

Has ‘gdb --version’ changed? It looks as if sed is looking for the 7.8 and not as sed now produces ‘GNU gdb (GDB; openSUSE 13.278’

Is this a openSuSE or QT problem?

Sounds like this, which apparently got fixed for 5.3.0: https://bugreports.qt.io/browse/QTBUG-34950
Try to change the sed line to the one mentioned here:
https://bugzilla.opensuse.org/show_bug.cgi?id=851105#c2

Apparently this comes from /usr/share/qt4/mkspecs/features/unix/gdb_dwarf_index.prf, changing it there should “fix” qmake.
