Fedora RPM Build
Structure
To build an rpm must be created and/or placed different files under `/usr/src/redhat` as follow:
- Spec file with details of name, dependencies, instructions, etc and script of how to build the rpm under `SPEC` folder
- Compressed file with the sources under `SOURCES` folder
Build
To build the new rpm, run the command:
# rpmbuild -ba SPEC/newrpm.spec
The created files will be placed as follow:
- New RPM created under `RPMS/system_architecture` folder
- RPM with sources and spec file packed under `SRPMS` folder
- Unpacked sources under `BUILD` folder
Scripts
There are 4 types of scripts:
- Pre install: pre
- Post install: post
- Pre uninstall: preun
- Post uninstall: postun
The `rpm` command has 3 main types of execution to be considered:
- install
rpm -i newrpm.rpm
- upgrade
rpm -u newrpm.rpm
- remove
rpm -e newrpm.rpm
and different values are passed to each script based on which type of execution is performed by the `rpm` command. More details on [[1]]
