Ah, another reason is to generate libfoo.so, you must name use "LOCAL_MODULE := foo" + "include $(BUILD_SHARED_LIBRARY)" using "LOCAL_MODULE := libfoo" will probably result in the generate of "liblibfoo.so" or something, and the build system might not like it.
I'm just speculating though. 2009/3/20 David Turner <[email protected]> > It might be that there is already another module named gps_hardware > somewhere in the build process, and that the error message is related to > that.
