Rpmbuild

rpmbuild (aka rpm-build) is a series of scripts and executable programs that are used to build packages using RPM.

Example usage

Note: In the following examples, I will use an actual build I did for the latest version of Raster3D.

As an regular user (not root) create a directory tree based on ~/rpmbuild:

cd
mkdir -p rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
echo '%-topdir %(echo $HOME)/rpmbuild' > .rpmmacros

• Download and unpack the latest tarball of Raster3D:

cd ~/rpmbuild/SOURCES
wget http://skuld.bmsc.washington.edu/raster3d/Raster3D_2.7d.tar.gz

• Make necessary changes to spec file, then execute:

rpmbuild -ba raster3d-2.9.spec

Example spec file

Note: This is a real spec file, used in building the Raster3D RPM.

%description
The Raster3D molecular graphics package consists of a core rendering program
and a number of ancillary programs that produce input files for rendering
from PDB (Protein Data Bank) files of atomic coordinates.  Raster3D can also
render images composed using other programs such as Molscript or XtalView.
Raster3D uses a fast Z-buffer algorithm to produce high quality pixel images
featuring one shadowing light source, additional non-shadowing light sources,
specular highlighting, transparency, and Phong shaded surfaces.  Output is to
a pixel image with 24 bits of color information per pixel.
Raster3D does not depend on graphics hardware.
