问题1：

frameworks/base/libs/utils/RefBase.cpp:507:67: error: passing ‘const android::RefBase::weakref_impl’ as ‘this’ argument of ‘void android::RefBase::weakref_impl::trackMe(bool, bool)’ discards qualifiers [-fpermissive]

[out/host/linux-x86/obj/STATIC_LIBRARIES/libutils_intermediates/RefBase.o] Error 1

解决方法：

$vim frameworks/base/libs/utils/Android.mk

#LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS)
LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) -fpermissive

问题2：

error: “_FORTIFY_SOURCE” redefined [-Werror]

解决方法：

$vim build/core/combo/HOST_linux-x86.mk

#HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
