链接器错误:未定义对_fini的引用 [英] Linker error: undefined reference to `_fini'

问题描述

我刚开始使用lpcXpresso进行嵌入式系统开发.它使用经过修改的Eclise作为其IDE，以及一个MCU C编译器和MCU链接器.

I am just getting strted with lpcXpresso for embedded system development. It uses a modifed Eclise as its IDE and an MCU C compiler and MCU linker.

我导入了一些新代码，并且出现了一些链接器错误，很快我就将其解决了.但是最后一个让我难过:

I imported some eisting code and had a few linker errors, which I soon sorted out. But the final one has me stumped:

undefined reference to `_fini'  

我希望这意味着我的一些代码调用了一个名为fini()的函数-对吗?

I would expect that that means that some of my code calls a function called fini() - right?

除了我没有一个(诚然有一个InitialzeTracingSubsystem()).而且我不认为链接程序会截断该名称，因为它先前曾抱怨_getimeofday.

Except that I don't have one (admiteddly there is an InitialzeTracingSubsystem()). And I don't believe that the linker is truncating the name because it earlier complained of _getimeofday.

知道我在做什么错吗?

推荐答案

您没有显示命令行.我猜想您直接使用了ld(链接器).

You didn't show your command line. I am guessing you've used ld (the linker) directly.

不要那样做.相反，总是使用编译器驱动程序进行链接.

Don't do that. Instead, always use the compiler driver to do the linking.

_init和_fini通常是libc或随附的C运行时启动文件(crt0.o，crtend.o等)的一部分.

The _init and _fini are usually part of libc, or the C runtime startup files (crt0.o, crtend.o, etc.) that come with it.

编译器驱动程序将进行必要的魔术操作以链接它们.链接器则不会.

The compiler driver will do the magic necessary to link them in. The linker would not.
