Question

我正在创建一个我想要在android和windows中使用的库。对于Windows，使用Visual Studio 2010，它可以编译，链接和运行。

对于Android，我使用的是带有android-ndk-r7的ndk-build脚本（使用gcc 4.4.3）。我收到了几个链接器错误：

./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

这是我的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)

我无法理解错误的含义和原因。任何人都可以对此有所了解吗？正如我所提到的，VC ++可以正常工作。

EDIT2 ：

更新了错误日志。这有帮助吗？

当我使用“nm RenderManagerImpl.o”时，我得到“V”符号和“_Z00004IRenderManager”的“00000000”地址。

EDIT3 ：似乎我将jonsenginetests变成共享库而不是静态编译。这意味着什么？

这是一个猜测，但该类名称听起来可能与RTTI有关，默认情况下在Android NDK中禁用。

假设我是对的，您可以通过在Android.mk文件中添加以下内容为您的应用启用RTTI：

LOCAL_CPP_FEATURES := rtti

有关详细信息，我建议您查看android NDK中的docs\ANDROID-MK.html和docs\CPLUSPLUS-SUPPORT.html

也可能是你正在使用android NDK不支持的标准库的一部分。它的默认支持相当有限。您可以在APP_STL中提供Application.mk来更改其使用的内容。例如：

APP_STL := gnustl_static

模糊链接错误与GCC，但不是VC ++
