Android x86 上与 NDK 和 STL 相关的参考错误
Android NDK and STL-related reference errors on x86
我正在构建与 V8 库的集成。此构建适用于 ARM（armeabi、armeabi-v7a）目标。
我想添加 x86 支持。今天是我第一次尝试这个。
我通过 make ia32.release.
为 x86 构建了 V8
我的Application.mk如下：
APP_ABI := armeabi armeabi-v7a x86
APP_PLATFORM := android-14
APP_STL := stlport_static
和Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_libbase
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_libbase.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_base
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_base.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_nosnapshot
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_nosnapshot.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_platform
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_libplatform.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8jsevaluator
LOCAL_SRC_FILES := v8jsevaluator.cpp
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include/
LOCAL_LDLIBS := -llog -landroid
LOCAL_STATIC_LIBRARIES := v8_base v8_nosnapshot v8_libbase v8_platform
LOCAL_CPP_FEATURES += exceptions
LOCAL_CFLAGS += -std=c++11
include $(BUILD_SHARED_LIBRARY)
在 x86 组件中构建失败，出现大量与 STL 相关的错误。

正如我所说，无需尝试构建 x86，这一切都可以。
谁能指出我哪里出错了？谢谢！
我将我的 V8 源代码从 4.1.0.22 升级到 4.9.385.30，在解决了很多其他问题之后，这个问题就消失了。
