急！！ 请高手解惑：Cygwin+NDK，make APP报错，无法生成.so

参考一下吧：

It's because the new Windows toolchain doesn't support Cygwin's drive
mapping (i.e. /cygdrive/c/ instead of C:/)
There is however a new function, called host-path, that you can use to
perform the translation from cygwin to windows,


you should call it as:


$(call host-path,<your-path>)


Note that this is a temporary measure. A future release of the NDK will
completely get rid of Cygwin (but host-path will still be provided and will
be a no-op).


Final note, host-path is automatically applied to the content of
LOCAL_C_INCLUDES (and LOCAL_EXPORT_C_INCLUDES). This is not the case for
LOCAL_CFLAGS or LOCAL_CPPFLAGS

First, the -L$(NDK_PLATFORMS_ROOT)/$(TARGET_PLATFORM)/arch-arm/usr/lib is
not needed.
Second, you can replace the second line with:

-L$(call host-path,$(MYPROJECTS)/Externals/precompiled/lib/Android) \


Note that NDK r5 now supports prebuilt libraries and module import. They are
probably a better way to achieve what you need here, since you have
precompiled stuff.
