模糊的鏈接錯誤與GCC，但不是VC++

Question

我正在製作一個庫，我的目標是在Android和Windows中使用。 對於使用Visual Studio 2010的Windows，它編譯，鏈接並正常運行。

對於Android，我使用的是android-ndk-r7（使用gcc 4.4.3）的ndk-build腳本。 我收到幾個這樣的鏈接錯誤：

./obj/local/armeabi-v7a/libjonsengine.a(RenderManagerImpl.o):(.data.rel.ro._ZTI1

collect2: ld returned 1 exit status 
make: *** [obj/local/armeabi-v7a/libandroidgame.so] Error 1 

這裏是我的Android.mk：

LOCAL_PATH:= $(call my-dir) 
TOP_PATH := $(LOCAL_PATH) 

include $(CLEAR_VARS) 
# Main engine 
LOCAL_MODULE := jonsengine 
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../include/ \ 
        $(LOCAL_PATH)/../include/Core/ \ 
        $(LOCAL_PATH)/../interface/ \ 
        $(LOCAL_PATH)/../include/Render/ \ 
        $(LOCAL_PATH)/../include/Utils/ \ 
        $(LOCAL_PATH)/../include/Memory/ 

# Core 
LOCAL_SRC_FILES := ../src/Core/Engine.cpp 

# Rendering 
LOCAL_SRC_FILES += ../src/Render/RenderManagerImpl.cpp 

# Utils 
LOCAL_SRC_FILES += ../src/Utils/LogManagerImpl.cpp \ 
        ../src/Utils/PortableTime.cpp 

# Memory 
LOCAL_SRC_FILES += ../src/Memory/MemoryManagerImpl.cpp \ 
        ../src/Memory/MemoryPool.cpp \ 
        ../src/Memory/dlmalloc.c 

LOCAL_CFLAGS := -DSTRUCT_MALLINFO_DECLARED 
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES) 
LOCAL_EXPORT_CFLAGS := $(LOCAL_CFLAGS) 
LOCAL_LDLIBS := -lGLESv2 -llog 

include $(BUILD_STATIC_LIBRARY) 



# Testing library 
include $(CLEAR_VARS) 

LOCAL_MODULE := jonsenginetests 
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../Tests/ \ 
        $(LOCAL_PATH)/../Tests/Memory/ \ 
        $(LOCAL_PATH)/../Tests/Core/ 

LOCAL_SRC_FILES := ../Tests/TestManager.cpp \ 
        ../Tests/Memory/MemoryManagerTest.cpp \ 
        ../Tests/TestClass1.cpp 

LOCAL_CFLAGS := 
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES) 
LOCAL_EXPORT_CFLAGS := $(LOCAL_CFLAGS) 
LOCAL_STATIC_LIBRARIES := jonsengine 
LOCAL_LDLIBS :=-llog 

include $(BUILD_STATIC_LIBRARY) 

我也看不透的意思，也不是錯誤的原因。任何人都可以對此有所瞭解？正如我所說的，它可以很好地與VC++。

EDIT2：

更新錯誤日誌。這有幫助嗎？

當我使用「nm RenderManagerImpl.o」時，例如，我得到'_ZTI4IRenderManager'的'V'符號和'00000000'地址。

EDIT3： 看來，如果我做jonsenginetests到一個共享庫，而不是靜態的它編譯。這意味着什麼？

感謝

這是一個有點猜測，但該類名字聽起來像它可能是與RTTI，它在默認情況下在Android NDK禁止做。

假設通過添加以下到您的Android.mk文件我的權利，你可以啓用RTTI爲您的應用程序：

LOCAL_CPP_FEATURES := rtti 

欲瞭解更多信息，我建議你在Android NDK在尋找docs\ANDROID-MK.html和docs\CPLUSPLUS-SUPPORT.html

也可能是因爲您正在使用android NDK不支持的標準庫的一部分。它的默認支持相當有限。您可以通過在Application.mk中提供APP_STL來更改它的用途。例如：

APP_STL := gnustl_static
