How to automate rebuilding of src.rpm packages?

Question

linux

Good afternoon.
I have centos 7.2 x86 and, as you know, there is no epel repository for it, but some packages from this repository are necessary for my tasks.
I do it like this:

1. I download the necessary src.rpm package from the epel repository.
   
2. Install it with rpm -Uvh
   
3. I go to ~/rpmbuild/SPEC
   
4. I put the dependencies necessary for the package with the yum-builddep file.spec command
   
5. Then I build the package with the command rpmbuild -ba file.spec
   

When building, at stage 4, there may be problems with dependencies, namely, you need a package that is not in the default repository and also needs to be built and installed. Hence the question - how can you automate the rebuilding of the src.rpm package so that the missing package is downloaded independently, built and installed?

Answer 1

you can use public services based on OBS, or COPR.
