Question

我到达最后一个链接命令（实际的可执行文件正在链接）但是我得到了一个未定义符号的BUNCH（它们在cpp中并且对我来说看起来很可怕，一个简单的c程序员）

- 它可能很简单，但我不能得到我应该把它作为链接器（它在这里使用gcc ......？是否合适？g ++告诉我太多输入文件lol）（ld返回大部分相同）

无论如何它的荒谬，我完全被卡住了

谢谢你的帮助！

Answer 1

似乎您正在尝试将C ++代码与C（gcc）链接器调用链接起来。那将不包括你正在看到的适当的库。尝试使用g ++而不是gcc（或丢弃C ++代码/库）。

Answer 2

添加-lstdc++或使用g ++进行链接。

链接错误：未定义的符号，很多符号（cpp交叉编译）
