errors when compiling for Android with ant

[adamski]

when I include this module and try and compile for android with e.g. ant release I get lots of errors such as the following:

     [exec] /Users/adamelemental/dev/SDKs/android-ndk/platforms/android-9/arch-arm/usr/include/sys/endian.h:56:24: error: expected unqualified-id before '__extension__'
     [exec]  #define __swap16gen(x) __statement({     \
     [exec]                         ^
     [exec] /Users/adamelemental/dev/SDKs/android-ndk/platforms/android-9/arch-arm/usr/include/sys/endian.h:141:18: note: in expansion of macro '__swap16gen'
     [exec]  #define __swap16 __swap16gen
     [exec]                   ^
     [exec] /Users/adamelemental/dev/SDKs/android-ndk/platforms/android-9/arch-arm/usr/include/sys/endian.h:158:16: note: in expansion of macro '__swap16'
     [exec]  #define swap16 __swap16
     [exec]                 ^
     [exec] ../../JuceLibraryCode/modules/stk/../../../../../juce_modules/drowaudio/stk_module/stk/stk.h:181:15: note: in expansion of macro 'swap16'
     [exec]    static void swap16( unsigned char *ptr );
     [exec]                ^

Do you have any suggestions why this might happen with ant but not with Xcode?

Hi Adam,

It looks like Android might be defining macro with the same name as a function in STK. Try undeffing all any symbol clashes at the top of the stk module header (and maybe the cpp header as well). E.g.

#undef swap16

Let me know if that gets rid on any errors.

I tried some of the suggestions from the JUCE forum, and also your advice on both the stk.h and stk.cpp files. However still getting complaints from ant. You can see the additions I've made on my fork https://github.com/adamski/stk_module/tree/android-undefs

Thanks for your help on this

See pull request for the solution that worked for me. Thanks
