This is related to my other question
When I build my project with Apportable, it assumes Linux/Android platform. I think these preprocessor flags are set.
__linux
ANDROID
But, my source code (OpenGL drawing) is not ready for Android, and only for iOS. So I want to detect some preprocessor flag for Apportable (not Linux or Android), and perform some iOS specific processing.
How can I detect Apportable platform in preprocessing stage? (What is pre-defined preprocessor flag for Apportable?)
You can easily verify if a preprocessor macro is defined by using the message pragma:
// will always print, to detect cases where file wasn't actually built
#pragma message "-------------------------ALWAYS----------------------------"
// if the macros are defined, the pragma message should be logged
#ifdef __linux
#pragma message "__linux"
#endif
#ifdef ANDROID
#pragma message "ANDROID"
#endif
This will print out warning messages for macros that are defined:
/.../KTTypes.h:15:9: warning: -------------------------ALWAYS---------------------------- [-W#pragma-messages]
#pragma message "-------------------------ALWAYS----------------------------"
^
/.../KTTypes.h:17:9: warning: __linux [-W#pragma-messages]
#pragma message "__linux"
^
/.../KTTypes.h:20:9: warning: ANDROID [-W#pragma-messages]
#pragma message "ANDROID"
So yes, ANDROID and __linux are both defined when building with apportable, and not defined when building from within Xcode.
ANDROID will be defined by the build system, however since the Apportable platform has numerous features that stock Android will not. APPORTABLE is defined to signify builds by the apportable build system.
You can find additional build flags specific for Apportable builds in
~/.apportable/SDK/site_scons/android/ndk.py
