- First cello package

The BuildRequires directive, which specifies build-time dependencies for the package, includes two packages that are needed to perform the compilation build process:

The Requires directive, which specifies run-time dependencies for the package, is omitted in this example. All runtime requirements are handled by rpmbuild, and the cello program does not require anything outside of the core C standard libraries.

The %build section reflects the fact that in this example a Makefile for the cello program was written, hence the GNU make command provided by the rpmdev-newspec utility can be used. However, you need to remove the call to %configure because you did not provide a configure script.

The installation of the cello program can be accomplished by using the %make_install macro that was provided by the rpmdev-newspec command. This is possible because the Makefile for the cello program is available.
