oracle linux yum -y install libmicrohttpd-devel No package libmicrohttpd-devel available.

The error message "No package libmicrohttpd-devel available" indicates that the package is not available in the repositories that are currently enabled on your system. You can try the following steps to resolve the issue:

1. Check if the package is available in any other repository by running the following command:

   yum search libmicrohttpd-devel

2. If the package is found, enable the repository that contains it. You can do this by editing the file `/etc/yum.repos.d/redhat.repo` or `/etc/yum.repos.d/oraclelinux.repo` and uncommenting the appropriate lines for the repository.

3. If the package is not found in any repository, you can download and install it manually from a trusted source. You can search for the package on the internet and download it in RPM format. Then, install it using the following command:

   rpm -ivh <package-name>.rpm

I hope this helps! Let me know if you have any further questions.
