x86上的Android NDK和STL相關參考錯誤

Question

我正在與V8庫建立集成。這個版本適用於ARM（armeabi，armeabi-v7a）目標。

我想添加x86支持。今天是我第一次嘗試這個。

我通過make ia32.release爲x86構建了V8。

我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) 

構建在x86組件失敗有很多關於STL的錯誤。

正如我所說的，沒有嘗試構建x86，這一切都OK。

請任何人都可以指出我要出錯的地方嗎？謝謝！

Answer 1

我將V8的源碼從4.1.0.22升級到4.9.385.30，並且在解決了很多其他問題之後，這個問題就消失了。
