android ndk 编译错误

Android NDK: NDK Application 'local' targets unknown ABI(s): armeabi armeabi-v7a x86
Android NDK: Please fix the APP_ABI definition in ...jni/Application.mk
/home/dongdy/0work/android-ndk-r10e/build/core/setup-app.mk:117: *** Android NDK: Aborting . Stop.

原来是权限问题，cd到ndk目录下，执行

chmod -R 777 *

------------------------------------------------------------------

另外 build/core/setup-app.mk这个文件好像少了一行：

# If APP_ABI is 'all', then set it to all supported ABIs
# Otherwise, check that we don't have an invalid value here.
#
ifeq ($(NDK_APP_ABI),all)    少了这一行？？？
NDK_APP_ABI := $(NDK_APP_ABI_ALL_EXPANDED)
_abis_without_toolchain := $(filter-out $(NDK_ALL_ABIS),$(NDK_APP_ABI))
ifneq (,$(_abis_without_toolchain))
$(call ndk_log,Remove the following abis expanded from 'all' due to no toolchain: $(_abis_without_toolchain))
NDK_APP_ABI := $(filter-out $(_abis_without_toolchain),$(NDK_APP_ABI))
endif
else
ifeq ($(NDK_APP_ABI),all32)
