Q. I need to build a source RPM, how do I build it?
A. In order to build a source RPM you need to use rpmbuild command. rpmbuild is used to build both binary and source software packages. A package consists of an archive of files and meta-data used to install and erase the archive files. The meta-data includes helper scripts, file attributes, and descriptive information about the package. Packages come in two varieties: binary packages, used to encapsulate software to be installed, and source packages, containing the source code and recipe necessary to produce binary packages.
You need to use .spec file to build the RPM file. Next type rpmbuild command as follows:
# rpmbuild -ba pakagename.spec

Whr do I find spec file?
You have to make it yourself (or get someone else to make it for you).
If you have the .src.rpm file, just rpm -ivh .src.rpm. You’ll find the spec file in /usr/src/packages/SPEC directory after instalation.
The answer is incorrect.
Once you have all sources and spec, (in rpmbuild/{SOURCES,SPEC} directories
the rpmbuild -bs is what you seek.
