rpmbuild

The rpmbuild scipt is setup to enable rpms to be build in a separate docker The advantage is:

• It keeps your main system clean of any development libraries
• Software is not compiled with unnecessary features/options, because previous installations of development files
• It will open the docker in interactive mode, in case the build fails at any given point. This allows one to debug the issue, before restarting the build procedure
• The build process will automatically check which files need to be added to the rpms. Currently only normal files and development files are supported
• If rpm-build from the repo is compiled, a faster (one time compile) is supported

The repository also contains the spec files for applications that I've currently build using this software

Currently it will only create RPM packages for Enterprise Linux 9 using either AlmaLinux or Rocky-Linux based containers

Preparation Enterpirse Linux 7

1. Install docker using your distros package manager. For Centos this could be installed using: sudo yum -y install docker rpm-build rpm-sign
2. Create a group called docker: sudo groupadd docker
3. Add your user account to the docker group: sudo usermod -aG docker $USER
4. Restart the docker daemon: sudo systemctl restart docker
5. Either restart your session or execute: newgrp docker

Preparation Enterprise Linux (EL) 8 and 9 based

1. EL8 and 9 default supports podman instead of docker. But the podman-docker rpm allows enable docker command support for podman. One additional advantage is no additional configuration is required to allow users to run containers. To install podman-docker execute: sudo dnf -y install podman-docker rpm-build rpm-sign

Download rpmbuild

Clone the project using git: git clone https://github.com/sandersn80/buildrpm.git

Usage

To compile an application already supplied in the repostiory:

1. Navigate to the applicable application directory, inside the rpmbuild directory. E.g.: cd rpmbuild/supertuxkart
2. Now execute the buildrpm command for the specific spec file: ../rpmbuild $(pwd) almalinux or ../rpmbuild supertuxkart.spec almalinux

To use this script to build your own application:

1. Navigate to the rpmbuild directory and create a new directory specific for the application for which you want to create an rpm: mkdir -p rpmbuild/MyApplication; cd rpmbuild/MyApplcation
2. Create the specifile within this directory or download/copy it to this location, in case a specfile is already available.
3. Now execute the buildrpm command for the specific spec file: ../rpmbuild $(pwd) almalinux or ../rpmbuild myapplication.spec almalinux
