如何安装 dl

我有动态加载库的代码。运行后出现如下错误make。

aaa.cpp:(.text+0x4ea): undefined reference to `dlopen'
aaa.cpp:(.text+0x50b): undefined reference to `dlerror'
aaa.cpp:(.text+0x54e): undefined reference to `dlsym'
aaa.cpp:(.text+0x560): undefined reference to `dlerror'
aaa.cpp:(.text+0x56f): undefined reference to `dlerror'
aaa.cpp:(.text+0x595): undefined reference to `dlclose'
aaa.cpp:(.text+0x5b8): undefined reference to `dlsym'
aaa.cpp:(.text+0x5ca): undefined reference to `dlerror'
aaa.cpp:(.text+0x5d9): undefined reference to `dlerror'
...

这让我觉得缺少了什么。在 Ubuntu 中dl安装的最佳方法是什么？dl
