"make arguments" via qmake?

[Asperamanca]

So if Qt Creator loads a .pro file (and assuming no .pro.user file exists), it simply ignores my settings?

I am aware that qmake does not invoke the make itself.
But basically, all I need is for my flag to appear in the makefile.

Tobias would have to fill in the details. You can definitely use CXXFLAGS to add compiler flags to Makefile. I don't know about adding other flags. You can get all available vars from "the reference":http://doc.qt.digia.com/qt/qmake-variable-reference.html.

MAKEFILE var is nice to look at - it allows to change the name of the makefile, so that you can use your own "main" file with standard name.

QMAKE_CXXFLAGS is only a part of what I need.

I need to be able to define make arguments, basically append to the environment variable MAKEFLAGS.
How would I do that with qmake commands?

[sierdzio]

DEFINES is a good start. As hinted above, I don't know how to do it cleanly. You can use the MAKEFILE variable trick (create your own Makefile with flags set, tell qmake to generate something like temp_makefile, link both files and voila) - it's nasty, but should work.

[Asperamanca]

The way I understand it, DEFINES is something different than an environment variable, and the make won't see it. Also, there does not seem to be a flag in qmake at all to pass on "makeflags", so the second best option would be for me to define an environment variable.

All I have that I give the compile server is the .pro file, so the environment variable would need to be set by qmake based on some function or variable within my .pro file.

Found a way to pass the option as a command line argument. Solved for me. Thanks!

How?

[Asperamanca]

Unfortunately, I don't remember and even after a lengthy search did not find what my original problem was. Sorry!

I have since learned to post my own solutions to my own threads.

@Asperamanca Can you please tell me how did you pass a variable to qmake?

Thanks,

If you set the environment variable MAKEFLAGS, the Make program will pass it to any sub-make call.

But nmake does no such thing, hence QMake redirects MAKEFLAGS to each of sub-nmakes, like:

@set MAKEFLAGS=$(MAKEFLAGS)
$(MAKE)

Also, the XD framework's QMake supports SUBMAKE_FLAGS, which just appends to command line (without changing MAKEFLAGS environement-variable).
