Hi,

I seem to recall, in the dim, distant past, using a Qt utility (qmake?) to

Indirectly: "qmake -query" will tell you all the directories where you find
parts of Qt and the QMAKE_SPEC that will be used for your own projects -
usually Qt was build with the same spec. What exact compiler flags will be
used is something that you'll find inside the definition of that spec.
You find the spec definition in $QT_HOST_DATA/mkspecs/$QMAKE_SPEC/qmake.conf
you have to follow all the includes as well as $QT_HOST_DATA/mkspecs/q*.pri
If you really want the compile settings of Qt and not the ones you should
use for your own project, then you need access to the actual Qt build
directory where you'll find those settings in the cache files.
...at least that's all I'm aware of. Maybe someone else knows a magic bullet
merchand? ;-)
It must have been another package I was thinking of, then. I recall being
able to retrieve the exact build flags for the framework, which could then be
applied verbatim to the project that depended upon it to ensure parity. For
some reason I thought that was Qt, but it must have been before I discovered
it so many years ago.
Thanks so much for your reply, Konrad.
