Re: [SailfishDevel] Check for OS in .PRO file
I use similar approach, but I do
qmake CONFIG+=sailfish
and then I can check for it in the .pro file like this:
sailfish {
DEFINES += Q_OS_SAILFISH
...
}
Looks shorter and cleaner to me :-)

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

In general, it might just be easier (and more maintainable) to have
a per-platform .pro file for your project and not litter your .pro
file with lots of conditionals (been there, done that - it will
become hard to read, understand and maintain as the number of
platforms grows). If there’s a lot of common things that you need in
each file, put that in a .pri file and include it in each
platform-specific .pro file. Then, in the sailfish .spec, you can
call qmake on the sailfish-specific project file, in the Maemo 5
debian/rules script, you call qmake on the maemo5 .pro file, etc…
With that said, you can use packagesExist[1] to do sailfish-specific
things if you are convinced that a single .pro file really is the
way to go:
packagesExist(sailfishapp) { .. do stuff .. }
Alternatively, set an environment variable in the qmake call in the
.spec file and check for that variable in the .pro file:
# In the .spec file:
IS_SAILFISH_OS=1 qmake
# In the .pro file:
IS_SAILFISH_OS = $$(IS_SAILFISH_OS)
contains(IS_SAILFISH_OS, 1) {
.. do stuff ..
}
HTH :)

Thanks,
Thomas' hint of avoiding the conditionals convinced me somehow :-)

Re: [SailfishDevel] Check for OS in .PRO file
Just for the record this will fail to build on the Community OBS or even in a
Mer Platform SDK using a SailfishOS target.
Thomas and Timur's suggestions would work.

Hi,
I should read my mails more often 8) Just figured out
win32|macx{

linux-g++{

}
contains(SDKHOSTNAME , "SailfishSDK"){

Re: [SailfishDevel] Check for OS in .PRO file
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

[SailfishDevel] Check for OS in .PRO file
Hi there,
first of all a happy new year to everyone! I had some time offline this
morning, so here comes a bunch of emails...
There are ways to check for the OS in QtCreator .PRO files, e.g. like
unix:symbian{ # do stuff}
unix:maemo5{ # do stuff}
macx{ # do stuff}
win32{ # do stuff}
Is there a way to check (or control to be more precise) that some directives
are only used when compiling on the MerSDL VM?
Just checking for the presence of "sailfishapp" does not work, because that is
defined for any OS.
