Adding #define to main .pro

Anonymous_Banned275

I like to add single place to control preprocessor entries AKA #define for example.

I can add "common #define" to subdir project subproject .pro

DEFINES += "TEST_FLOW_CHART"

works as expected

Adding same to main .pro file does not work.
Is there any other way / place to have / add common directives ?

I believe GCC has some "additional processing" options, but I forgot how to do that . But doing this in main .pro would be proffered.

Yes, you can, for example, create a common.pri file like:

DEFINES += QT_NO_CAST_FROM_ASCII QT_NO_CAST_TO_ASCII

Then include that *.pri from all of your *.pro files, like:

include(../common.pri)

Of course, adjust the path to common.pri accordingly.

Here's a real-world (albeit pretty old) example from one of my open source projects:

./common.pri
./src/src.pro - includes common.pri
./test/test.pro - also includes common.pri

Cheers.

@Paul-Colby Thanks for the reply. Just for sake of discussion - what would be the benefit of adding EXTRA file to EACH suboproject ?
Besides it does not meet the post " specification" to " add single place to control preprocessor" to main .pro.
