I am trying to install mycrypt-1.0.4 on RHEL 8 and it says mycrypt.h error Reinstall libmcrypt. So, I am trying to install libmcrypt and I copied libmcrypt-2.5.8.tar.gz into tmp folder. Now when I ran this command

sudo dnf install /tmp/libmcrypt-2.5.8.tar.gz

it throws error. What I am doing wrong here? Please correct me.

What I have tried:

sudo dnf install /tmp/libmcrypt-2.5.8.tar.gz

The file /tmp/libmcrypt-2.5.8.tar.gz is almost certainly a source code tar-ball, not a RedHat RPM. For RedHat based distros, libmcrypt is part of epel, so you will have to do something like

Bash

sudo dnf update
sudo install epel-release
sudo install libmcyrpt-devel

That will install not only libmcrypt headers, but also libmcrypt, and any package dependencies.

To build mcrypt from source the procedure is something like:

Bash

tar xf /tmp/libmcypt-2.5.8.tar.gz
cd libmcrypt.2.5.8
./configure
make
sudo make install

That will probably install under /usr/local, so you may have to either add LD_LIBRARY_PATH=/usr/local/lib64 to your .profile, or add an entry /usr/local/lib64 to /etc/ld.config.d/ and then sudo ldconfig

Thank you for your reply. Can you tell me where can I download rpm version of libmcrypt?

dnf downloads and installs packages for you. All you need to do is as noted above
sudo dnf install libmcrypt-devel
That will download and install the latest libmcrypt-devel package (headers and probably a pkg-config profile). If you do not already have the latest libmcrypt package installed, that will be downloaded and installed or updated too. If libmcrypt or libmcyrpt-devel requres another package, for example say libImNeedtedToo, then it will be downloaded and installed for you too, as will anything libImNeededToo requires, and so on.
