How to resolve the issue of command not found in Linux when using gcc?

If you encounter the error message “gcc: command not found” in Linux, it means that the GCC compiler is not installed on your system. To resolve this issue, you can follow the steps below:

1. Firstly, use the following command to check if the system already has the GCC compiler installed:

gcc --version

If GCC is already installed in the system, it will display the version information; otherwise, it will prompt “command not found”.

1. If GCC is not installed in the system, you can use the following command to install the GCC compiler:

To install on Debian or Ubuntu systems, use the apt command.

sudo apt install gcc

To install on CentOS or RHEL systems, use the yum command.

sudo yum install gcc

1. What version of gcc are you using?

Please be aware that in certain Linux distributions, additional packages may need to be installed, such as build-essential or development tools, in order to install GCC and other development tools. The specific commands may vary, so please make adjustments according to your system and distribution.

I hope the above information is helpful to you!
