[solved] trying to add/modify arguments for make...

...but they don't seem to be taking (according to the information in the Compile Output window).

In my .pro file, I have:

@win32: {
INCLUDEPATH += /boost_1_49_0
QMAKE_CXXFLAGS_RELEASE += -O3 -pipe
}
@

I don't know if "win32" is right; I'm just guessing here. I've also tried "win" and "win64" with the same results.

Do I need to "declare" this "win32" (or whatever) to Qt to get it to pick this up from the .pro file? Or, is there some other step I'm missing?

Thanks.

Try it without the :

It said "configuration unchanged, skipping qmake step."

Since that's a qmake flag, I'm not sure what to do about this.

Have you run qmake manually from the build menu?

No, I hadn't. Just did it, but it still wouldn't rebuild. So I did a clean, and then built. It looks like the parameters took. Thanks.

I'll ask you the same question that I've asked others, and no one seems to want to answer: where can I find a list of legal values like "win32" and "macx"? I couldn't find them in the qmake documentation page.

Can someone please answer this for me? I need to put something into a .pro file for linux-only builds, and I can't find anything about that in:

"qmake reference manual":http://qt-project.org/doc/qt-4.7/qmake-variable-reference.html

Again, I'm looking for the list of tags or whatever they're called, like the "win32" in my first post.

For Linux stuff, you can use the "unix" tag. Again, I don't know of a complete list. Not saying there isn't one, but I just don't know offhand.

OK, thank you, mlong. Am I missing something here, or is it a little strange that there isn't some list of those tags? I mean, how is a beginner (like me) supposed to know about this stuff other than pestering the forum?

It really seems to me like it should be documented somewhere...

I don't know of an exhaustive list. The issue also stems from the fact that scoping operators aren't limited to just OS types. There are a number of different conditions which can be tested against (whether you're debugging or in release mode, other variables, etc.)

The best I can offer off the top of my head is the "scopes":http://qt-project.org/doc/qt-4.8/qmake-advanced-usage.html section in the qmake manual.

[Edit: changed link]

Also, to quote from that same doc page:

bq. In addition to the win32, macx, and unix values used in many scope conditions, various other built-in platform and compiler-specific values can be tested with scopes. These are based on platform specifications provided in Qt's mkspecs directory.

Oh, I hadn't seen that page. That's got some very helpful stuff. Thanks, mlong.

You're very welcome!
