[SOLVED] Where is the header socket.h on CentOS 8?

Issue

On Ubuntu 20.04 I have:

$ dpkg -S /usr/include/x86_64-linux-gnu/sys/socket.h 
libc6-dev:amd64: /usr/include/x86_64-linux-gnu/sys/socket.h

Whereas in a docker container with CentOS 8, there is no file /usr/include/x86_64-linux-gnu/sys/socket.h and if I try

$ yum whatprovides socket.h

Error: No Matches found

and

$ rpm -q --whatprovides socket.h
no package provides socket.h

Solution

You can pass wildcards to yum whatprovides:

$ yum whatprovides /usr/include/*sys/socket.h

So your answer is glibc-headers.
