Creating a RPM Package for a POCO Application

Here is a RPM spec file template (pocoServiceExample.spec) for creating a RPM package for a POCO-based server application. Requires the systemd .service file. Contributed by Jeff Adams.

To build the package with rpmbuild:

$ rpmbuild -bb --define 'PSEDIR /SOMEROOTDIR' pocoServiceExample.spec

pocoServiceExample.spec

Name: Poco Service Example
Version: 1.0.0.0
Release: 1

%description
Best Darn Poco Service Ever shows how to use a Poco Service in a *nix enviroment that is built with a modern gcc and uses systemd instead of System V init scripts
