Hi,
What Thomas said makes sense, I just want to add one more little thing. You
can, in the .spec file, add stuff to qmake, like this define. This would
make the necessary code shorter and as a bonus, it gives you something you
can even ifdef in C++.
# spec file
qmake DEFINES+=IS_SAILFISH_OS
# pro file
contains(DEFINES, IS_SAILFISH_OS) {
...
}
// C++ file
#if defined(IS_SAILFISH_OS)
...
#endif
Cheers,
Timur
