[solved] Qt 5.2.0 on iOS Q_OS_IOS is not defined when running in iOS Simulator

[jraichouni]

In iOS simulator "MAC MAC MAC" gets written into the output.
Can anybody confirm that?
@
int main(int argc, char *argv[]) {
#if defined(Q_OS_IOS)
qDebug() << "IOS IOS IOS";
#endif
#if defined(Q_OS_MAC)
qDebug() << "MAC MAC MAC";
#endif
return 0;
}
@

Same behaviour when running on device? May be Qt bug?
Would like to try that directly on the iPhone, but I am still waiting for my dev account activation.

Hi,

There's something not clear in your post. Are you getting different result between your first and your second code example ?

[jraichouni]

updated my post

Someone wrote (Don't know, why it is not visible here anymore)

bq. "It's not a bug, Q_OS_MAC is for OS X and Q_OS_IOS is for iOS"

How should one differentiate if the application is running on OSX or iOS (simulator) if one uses OSX and iOS simulator only? I expected a real simulation of being on the iPad/ iPhone. This seems to be currently not supported by this #define.

That someone was me, before I saw your corrections and the X missing.

Here's the explanation:
Q_OS_MAC is for Darwin type OSs, if you want to make the difference between iOS and OS X use Q_OS_MACX and Q_OS_IOS

[jraichouni]

Nope, if I code

@
int main(int argc, char *argv[]) {
#if defined(Q_OS_IOS)
qDebug() << "IOS";
#elif defined(Q_OS_MACX)
qDebug() << "MACX";
#endif
return 0;
}
@

I get the output "MACX" in both cases (on my OSX desktop and within iOS simulator) :-(

[jraichouni]

Q_OS_IOS seems to be undefined in iOS Simulator as the following brings no output:
@
int main(int argc, char *argv[]) {
#if defined(Q_OS_IOS)
qDebug() << "IOS";
#endif
}
@

Just tested (Qt built from git) and I get the correct answers

[jraichouni]

Okay, made a new small project and can commit, that it works.
Need to analyse, what went wrong!

Sorry for that!
Germans say: "Asche auf mein Haupt!"

It is crazy, in the project context it wents wrong, in a small testproject it succeeds.
Should go to bed.

Found the cause:

@
QMAKE_CXXFLAGS += $$system(mapnik-config --cxxflags)
QMAKE_CXXFLAGS += $$system(mapnik-config --includes --dep-includes)
@

have been defined in my projects .pro file.
This results into Q_OS_IOS to be undefined on iOS simulator.
@mapnik-config --cxxflags@

results into

@-ansi -Wall -ftemplate-depth-300 -O3 -fno-strict-aliasing -finline-functions -Wno-inline -Wno-parentheses -Wno-char-subscripts@

and

@mapnik-config --includes --dep-includes@

results into
