Hi all
I have a DEFINES QMake directive in my project .pro file which
(should) allow me to respond to this with #if #ifdef C++ preprocessor
macros in my main.cpp file.
Let assume I have the following
//.pro file
DEFINES += TEST_A
//main.cpp
#ifdef TEST_A
//Do Something
#endif
#ifdef TEST_B
//Do Something different
#endif
I build and run my code. As expected, "Something" happens, "Something
different" does not.
I then change the pro file
DEFINES += TEST_B
# DEFINES += TEST_A
and build and run again. I expect "Something" to be skipped and
"Something different" to happen.
Instead the "Something" happens. i.e. it is as if I made no change to
the .pro file.
If I then clean the project, and build and run again, then I get the
expected results "Something different".
i.e. changes to the DEFINES setting only take effect once a project
has been cleaned.
I suspect that this is a more general Qt / QMake problem rather than a
Sailfish specific one.
I am running the Sailfish Alpha 2 (Qt5) hosted on OSX.
Grüsse
Chris
