How To Install mcpp on CentOS 8
Introduction
In this tutorial we learn how to install mcpp on CentOS 8.
What is mcpp
C/C++ preprocessor defines and expands macros and processes ‘#if’, ‘#include’ and some other directives. MCPP is an alternative C/C++ preprocessor with the highest conformance. It supports multiple standards MCPP is especially useful for debugging a source program which uses complicated macros and also useful for checking portability of a source. Though mcpp could be built as a replacement of GCC’s resident preprocessor or as a stand-alone program without using library build of mcpp, this package installs only a program named ‘mcpp’ which links shared library of mcpp and behaves independent from GCC.
We can use yum or dnf to install mcpp on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install mcpp.
Install mcpp on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00
CentOS Linux 8 - ContinuousRelease 43 kB/s | 3.0 kB 00:00
CentOS Linux 8 - Extras 23 kB/s | 1.5 kB 00:00
CentOS Linux 8 - FastTrack 40 kB/s | 3.0 kB 00:00
CentOS Linux 8 - HighAvailability 36 kB/s | 3.9 kB 00:00
CentOS Linux 8 - Plus 24 kB/s | 1.5 kB 00:00
CentOS Linux 8 - PowerTools 50 kB/s | 4.3 kB 00:00
Extra Packages for Enterprise Linux Modular 8 - x86_64 13 kB/s | 9.2 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00
Metadata cache created.
After updating yum database, We can install mcpp using dnf by running the following command:
sudo dnf -y install mcpp
Install mcpp on CentOS 8 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh

After updating yum database, We can install mcpp using yum by running the following command:
sudo yum -y install mcpp
How To Uninstall mcpp on CentOS 8
To uninstall only the mcpp package we can use the following command:
sudo dnf remove mcpp
