Android NDK, why are you using my system headers?

[ol...@illusionlabs.se]

I'm trying to set up a huge pile of code built for another platform on
Android (runs on OSX and iOS)
I thought I had everything under control, but then this build error appeared:

[armeabi-v7a] Compile++ thumb: common <= Device.cpp
In file included from jni/src/Device.cpp:8:
In file included from /usr/include/sys/sysctl.h:83:
In file included from /usr/include/sys/ucred.h:76:

#include "mach/arm/boolean.h"
         ^
1 error generated.
make: *** [obj/local/armeabi-v7a/objs/common/src/Device.o] Error 1

I'm building on OSX, and as you can see, it points to files in
/usr/include, that is, the headers of my OS! 

(and fails because my PC is not running arm...)

Anyone has any idea what I might have messed up?

It is not listed on the command line, so is it provided in some env variable?

I'm using the LLVM compiler, gnulibc++, and NDK r9c

sys/sysctl.h seems to not be available in Android, so I have to fix
this with a patch to my code, but the fact it tries to look in /usr/include makes
me worry it does the same for other headers too, and I will have lots
of trouble down the road because of it..

Even if this is just a side effect of it not being available in
"platforms/android-xx/arch-arm/usr/include" in the NDK, I'd rather
like it if /usr/include/ was not available at all for my NDK build...

Any ideas?

Cheers,
Olof

Did you find a solution for this?

I suggest that you try to run `ndk-build V=1`. You will see all the compilation flags and settings in your build log, and this can help you find out what messed up. I never had such problems on Mac nor on other platforms.
