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?
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...
