Compiling ICU for Android - 'uint64_t' does not name a type

Question

While attempting to cross-compile ICU using android-ndk-r7 in Linux, the following error occurs after configuration when I run \'make\'

__/android-ndk-r7/pla         


        

Answer 1

The main issue is that uint64_t isn't a defined type in C versions prior to C99. The best way to have it defined is to tell gcc which standard you'd like to use.

For c++, that's passing the -std=gnu++0x flag. For C, that's passing -std=c99

I.e. add a line something like

APP_CPPFLAGS= -std=gnu++0x

to your Application.mk file.

Alternatively, you can just hack it via your #define; I just wouldn't distribute code with such a hack as it's fragile.
