與GCC的模糊鏈接錯誤，但與VC ++無關

Question

我正在制作一個旨在在android和Windows中使用的庫。 對於Windows，使用Visual Studio 2010可以編譯，鏈接和正常運行。

對於Android，我將ndk-build腳本與android-ndk-r7（使用gcc 4.4.3）一起使用。 我收到以下幾個鏈接器錯誤：

./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)

我無法弄清楚該錯誤的含義或原因。 任何人都可以對此有所了解嗎？ 正如我提到的，它在VC ++上可以正常工作。

編輯2 ：

更新了錯誤日志。 這有什么幫助嗎？

例如，當我使用“ nm RenderManagerImpl.o”時，將獲得“ V”符號和“ _ZTI4IRenderManager”的“ 00000000”地址。

EDIT3 ：看來如果我將jonsenginetests做成一個共享庫而不是靜態庫，它將進行編譯。 這意味着什么？

謝謝

這只是一個猜測，但類名聽起來可能與RTTI有關，在Android NDK中默認禁用該類。

假設我是對的，您可以通過將以下內容添加到Android.mk文件中來為您的應用程序啟用RTTI：

LOCAL_CPP_FEATURES := rtti

有關更多信息，建議docs\\CPLUSPLUS-SUPPORT.html在android NDK中的docs\\ANDROID-MK.html和docs\\CPLUSPLUS-SUPPORT.html中docs\\CPLUSPLUS-SUPPORT.html

也可能是您使用的是android NDK不支持的部分標准庫。 它的默認支持是相當有限的。 您可以通過在Application.mk提供APP_STL來更改其使用的APP_STL 。 例如：

APP_STL := gnustl_static
