我重新安装这些库：gcc build-essential manpages-dev make perl zlib1g zlib1g-dev libssl-dev linux-libc-dev
但是不起作用

如果你想在典型的（Ubuntu）Linux中编译C代码，你需要“g”包。

"limits.h"和C++<limits>不是一回事。Equivalence of and否则，您可能会丢失C标准库。Clang doesn't see basic headers
为了确保这一点，首先使用
-v标志进行编译，以查看它在哪里查找这些头文件，这样您就可以验证它们是否存在。确保你已经安装了C头文件（例如，包名
libstdc++）。此外，请确保使用必要的标志（-std=c++，-stdlib=libstdc++）编译C++文件。
