如何在 Ubuntu 的共享库中列出导出的函数

2022-01-11 00:00:00 ubuntu linker c++

我刚刚在 Ubuntu 上构建了一个共享库,当我尝试使用该功能时,加载该库的应用程序报告找不到 'xxx' 符号.

I have just built a shared lib on Ubuntu, and when I attempt to use the function, the application that loads the library is reporting 'xxx' symbol not found.

我想检查(即列出)我的库导出的函数,以便进一步调查此问题.

I want to check (i.e. list) the functions that are exported by my library so I can investigate this issue further.

推荐答案

试试 nm 实用程序.

Try the nm utility.

GNU nm 列出对象中的符号文件 objfile.... 如果没有目标文件被列为参数,nm 假设文件 a.out.[参考]

GNU nm lists the symbols from object files objfile.... If no object files are listed as arguments, nm assumes the file a.out. [reference]
