Qmake: How to pass linker flags?
-
I am trying to pass a linker flag to VS2010.
Currently I am using
@QMAKE_LFLAGS += /OPT:NOREF@but that doesn't work, the flag does not appear in the resulting makefile.
How do I pass linker flags correctly?
-
There's also:
@
QMAKE_LFLAGS_WINDOWS
QMAKE_LFLAGS_WINDOWS_DLL
@But the standard one you've used should work. Or try adding your flags to LIBS, maybe that would work.
-
According to the qmake docs, LIBS would not be for that. It also doesn't affect the makefile.
I've now tried without any conditions, and verified using 'message' that the QMAKE_LFLAGS and/or QMAKE_LFLAGS_WINDOWS are set correctly. They are.
As a side node, none of the other options already in the QMAKE_LFLAGS appear in the makefile.Mystified & Frustrated...
-
I am having the same issue. Really? The QMAKE_LFLAGS setting really doesn't work?
How is this possible? I am astonished.
Would the current Qt team like me to investigate why this is failing?
-
After looking carefully at what is going on - Doing a "Clean All" and then rebuild through Qt Creator is not sufficient to pick up any changes to the linker flags such as those provided by the QMAKE_LFLAGS entry in the .pro file.
You need to actually delete the entire debug / delete build directory, and then do a rebuild.
Then, the linker flags take effect.
-
Another option is to re-run qmake after you have changed .pro file.
Or run "make distclean" to remove all generated files including top-level Makefile, so next build will re-recreate Makefile with new options. -
Yep! The Makefile is not regenerated...
