This should do it :
这应该这样做：
#include <cstring>

#include <cstring>
Your program may also be looking for ::strleninstead of std::strlen. If this is the case, try
您的程序也可能正在寻找::strlen而不是std::strlen. 如果是这种情况，请尝试
using std::strlen;

did you install all packages you needed?
你安装了你需要的所有软件包吗？
- try g++ --version and see if it gives something.
- check /usr/lib/include/ for string.h.
- 试试 g++ --version 看看它是否给出了一些东西。
- 检查 /usr/lib/include/ 中的 string.h。
If those things are not there, you need to check if the correct package is installed or not.
如果这些东西不存在，您需要检查是否安装了正确的软件包。
