To create a Golf installation package for Fedora or RedHat (or similar based on those, like Rocky), first get Golf source code. To do that, install git first:
sudo dnf install git
Then get Golf source code:
git clone https://github.com/golf-lang/golf.git
cd golf
For Redhat/Rocky/etc. install EPEL:
sudo dnf install epel-release
Next, install rpm-build package:
sudo dnf install rpm-build
sudo dnf install spectool
sudo dnf install rpmdevtools
Just to be sure wget is installed:
sudo dnf install wget
Get the fedora.spec file from Golf's github repo:
wget 'https://raw.githubusercontent.com/golf-lang/golf/refs/heads/main/fedora.spec' -O fedora.spec
Create directory structure for RPM build:
spectool -g -R fedora.spec
Next, get the dependencies for Golf (i.e. packages needed to build it):
sudo dnf builddep -y fedora.spec
The Golf source code already contains necessary spec files to produce a .rpm package. So you can just do this from command line:
rpmbuild -ba fedora.spec
In the home directory, this will produce file ~/rpmbuild/RPMS/x86_64/golf-<version>-1.<distro>.x86_64.rpm (where <version> is the Golf's current version, and <distro> is a shorthand for Linux distro), and you can now copy that file to another system with the same Linux installed, and install Golf with:
sudo dnf install ~/rpmbuild/RPMS/x86_64/golf-<version>-1.<distro>.x86_64.rpm
