Hi guys, get a problem when compiling RTPhysics android, which has bothered me for a whole day

Using latest RTPhysics source with ndk r8 and compile on windows 7 64

click build.bat and after ndk-build, got this error:

.... -Wl,--fix-cortex-a8 -Wl,--no-undefined -Wl,-z,noexecstack -LE:/android-n
dk-r8/platforms/android-8/arch-arm/usr/lib -lGLESv1_CM -ldl -llog -lz -lc -lm -o
obj/local/armeabi-v7a/libRTPhysics.so, ...) failed.
make (e=87):
make: *** [obj/local/armeabi-v7a/libRTPhysics.so] Error 87

Is this due to LOCAL_SRC_FILES in android.mk exceeds windows limitation or anything else?
I could compile and run other android examples successfully in same environment.

Thank you!
