The aim of this post is showing a tidy way to structure a C o C++ project managing the build lifecycle using the GNU Make and packaging it as RPM.
The post demonstrates a full featured C project managed by make and packaged as RPM, showing how to set up a tidy structure, develop and package a C application with its own shared objects, that reads the configuration from a file, validates settings, logs events into a file and handles error conditions printing to standard error and setting properly shell return code.
This post is certainly useful not only to developers, but to anybody who wants to learn how to build third part C or C++ software, since it clearly describes the compilation and linking process. In addition to that, we also learn how to create the product certificate that can be exploited by the subscription-manager to know that the product is installed on the system.
The application is then packaged, besides as a gzipped tarball, also as RPM, creating the application package, the package with the development resource files (the C include files) and the package with the debug information that can be used with a debugger to troubleshoot things.
