未找到 string.h 文件

Question

#include <string.h> 

Clang doesn't find string.h . Then I give it a better path but another file is not found:

[build] /usr/include/string.h:26:10: fatal error: bits/libc-header-start.h: No such file or directory
[build]  #include <bits/libc-header-start.h>
[build]           ^~~~~~~~~~~~~~~~~~~~~~~~~~

What should I do?

Can I just download string.h for my "llvm" environment and paste it there?:

/usr/include/llvm-10/llvm

Answer 1

If you are on an ubuntu system and encounter such problems in the future, you can find the answer by typing this command:

apt-file search bits/libc-header-start.h

Then download the corresponding library file using apt-get install xxx . If it is a red hat system or other, there should be similar commands.

Answer 2

String.h not found but why

Ok here is just a picture of the bad line. What is going on there. I am using clang and this clangd. Why can't it just find the correct library xD
