c – GCC：简单继承测试失败

由于我在应用程序中遇到的错误,我很生气,所以我做了一个简单的测试程序：

class Base
{

public:

    Base() { }
    virtual ~Base() { }


}; // class Base

class Vehicle : virtual public Base
{

public:

    Vehicle() : Base() { }
    ~Vehicle() { }


}; // class Vehicle

class Car : public Vehicle
{

public:

    Car() : Base(),Vehicle() { }
    ~Car() { }

}; // class Car

int main(int a_Data,char** argv)
{
    Car* stupid = new Car();

    return 0;
}

看起来很简单,对吧？这是我编译它的方式,这与我编译其余代码的方式相同：

/home/oem/android-ndk-r3/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/arm-eabi-g++
-g 
-std=c99 
-Wall 
-Werror 
-O2 
-w 
-shared 
-fshort-enums 
-I ../../YoghurtGum/src/GLES 
-I ../../YoghurtGum/src 
-I /home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/include 
-c src/Inheritance.cpp 
-o intermediate/Inheritance.o

(为清楚起见,添加了换行符).编译好了.但接着我们到了链接器：

/home/oem/android-ndk-r3/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/arm-eabi-gcc
-lstdc++ 
-Wl,--entry=main,-rpath-link=/system/lib,-rpath-link=/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib,-dynamic-linker=/system/bin/linker,-L/home/oem/android-ndk-r3/build/prebuilt/linux-x86/arm-eabi-4.4.0/lib/gcc/arm-eabi/4.4.0,-L/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib,-rpath=../../YoghurtGum/lib/GLES 
-nostdlib 
-lm 
-lc 
-lGLESv1_CM  
-z 
/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib/crtbegin_dynamic.o 
/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib/crtend_android.o
intermediate/Inheritance.o 
../../YoghurtGum/bin/YoghurtGum.a 
-o bin/Galaxians.android

正如你可能会说的那样,那里并没有真正需要的很多东西.那是因为它不起作用.它失败并出现以下错误：

intermediate/Inheritance.o:(.rodata._ZTI3Car[typeinfo for Car]+0x0): undefined reference to `vtable for __cxxabiv1::__si_class_type_info'
intermediate/Inheritance.o:(.rodata._ZTI7Vehicle[typeinfo for Vehicle]+0x0): undefined reference to `vtable for __cxxabiv1::__vmi_class_type_info'
intermediate/Inheritance.o:(.rodata._ZTI4Base[typeinfo for Base]+0x0): undefined reference to `vtable for __cxxabiv1::__class_type_info'
collect2: ld returned 1 exit status
make: *** [bin/Galaxians.android] Fout 1

这些是我从实际应用程序中获得的相同错误.

如果有人能够向我解释我在测试中出错的地方或者我在链接器中忘记了什么选项,我会非常非常感激.

提前致谢.

更新：

当我使我的析构函数非内联时,我会得到新的更令人兴奋的链接错误：

intermediate/Inheritance.o:(.rodata+0x78): undefined reference to `vtable for __cxxabiv1::__si_class_type_info'
intermediate/Inheritance.o:(.rodata+0x90): undefined reference to `vtable for __cxxabiv1::__vmi_class_type_info'
intermediate/Inheritance.o:(.rodata+0xb0): undefined reference to `vtable for __cxxabiv1::__class_type_info'
collect2: ld returned 1 exit status
