好的，这是我得到的输出：

arm-none-linux-gnueabi-ld --entry=main -dynamic-linker=/system/bin/linker -rpath-link=/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib -L/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib -nostdlib -lstdc++ -lm -lGLESv1_CM -rpath=/home/oem/android-ndk-r3/build/platforms/android-5/arch-arm/usr/lib -rpath=../../YoghurtGum/lib/Android -L./lib/Android intermediate/Alien.o intermediate/Bullet.o intermediate/Game.o intermediate/Player.o ../../YoghurtGum/bin/YoghurtGum.a -o bin/Galaxians.android

make: *** [bin/Galaxians.android] Fout 1

这是我设法破译的一个错误：

intermediate/Game.o: In function `Galaxians::Init()':
/media/YoghurtGum/Tests/Galaxians/src/Game.cpp:45: undefined reference to `__cxa_end_cleanup'
/media/YoghurtGum/Tests/Galaxians/src/Game.cpp:44: undefined reference to `__cxa_end_cleanup'

这是第 43 到 45 行：

Assets::AddSprite(new Sprite("media\\ViperMarkII.bmp"),     "ship");
Assets::AddSprite(new Sprite("media\\alien.bmp"),           "alien");
Assets::AddSprite(new Sprite("media\\bat_ball.bmp"),        "bullet");

所以，我觉得有趣的是第一个 new 很好（第 43 行），但第二个不是。这是什么原因造成的？

intermediate/Game.o: In function `Player::Update()':
/media/YoghurtGum/Tests/Galaxians/src/Player.h:41: undefined reference to `__cxa_end_cleanup'

new 的另一个问题：

Engine::game->scene_current->AddObject(new Bullet(m_X + 10, m_Y));

我不知道从哪里开始处理其他问题。

这些是我的 makefile，它们是一团糟，因为我只是想让它工作。

【解决方案1】：

您似乎没有链接正确的 C++ 运行时库（可能与 libstdc++ 不同）。您应该尝试使用 C++ 编译器来驱动链接器，而不是直接调用链接器。

如果你需要通过编译器传递链接器特定的选项，你可以使用 -Wl:

arm-none-linux-gnueabi-g++ -Wl,--entry=main -Wl,-dynamic-linker=/system/bin/linker ...

【讨论】：

谢谢，原来如此。 :)

【解决方案2】：

我刚刚遇到了很相似的问题，我从同事那里得到了答案。

   LOCAL_CFLAGS += -frtti

它使链接器将“运行时类型信息”包含在您可能在代码中使用的二进制文件中。
