Linux C ++：链接器输出奇怪的错误

Question

Alright, here is the output I get:

Here's an error I managed to decipher:

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'

This is line 43 through 45:

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");

So, what seems funny to me is that the first new is fine (line 43), but the second one isn't. What could cause this?

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

Another issue with new :

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

I have no idea where to begin with the other issues.

These are my makefiles, They're a giant mess because I'm just trying to get it to work.

Any help would be appreciated.

Answer 1

It looks like you are not linking the proper C++ runtime libraries (which can be different then libstdc++). You should try using the C++ compiler to drive the linker rather then invoking the linker directly.

If you need to pass linker specific options via the compiler, you can use -Wl:

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

Answer 2

I just had very similar problem, and I got the answer from colleagues.

   LOCAL_CFLAGS += -frtti

It makes linker to include the "Runtime type info" into the binaries which you may use in your code.
