Now that your .spec file is complete, the only thing left is the actual RPM build, which is what we’ll do in the fifth and last part of this series, “Making RPMs, part 5: Building the RPM.” Originally RPM stood for "Red Hat Package Manager" but now it is a recursive acronym "RPM Package Manager". The file where all the instructions and information needed to build an rpm package are defined is the .spec file. This page offers a quick overview of RPM scriptlets and a number of common recipes for scriptlets … The version number is hardcoded into the SPEC, however should you so choose, it can be set explicitly by passing an argument to rpmbuild directly: $ rpmbuild --define "_version 0.6.3" Manual spec file. In my case that was the installer script and a little help from the rpm command line program (the rpm tools are available on Mac OS via homebrew) rpm -qp --scripts name-of-rpm.x86_64.rpm Multiple packages can be built from a single RPM spec file, if desired. RPM has fully recursive spec file macros. A specfile contains, among the other things, the build dependencies (the software needed to compile the program we want to package), the runtime dependencies (the libraries needed for the program to run correctly) … Simple macros do straight text substitution. I will explain the layout of the spec-file in detail. When scriptlets are called, they will be supplied with an argument. These bits of code are called scriptlets and are mostly used to update the running system with information from the package. Working with SPEC files¶ As a RPM Packager, you will likely spend a large majority of your time, when packaging software, editing the SPEC file. SPEC file. If there was one thing that you should know about creating a rpm it’s how to write the spec file. Like the %files list in a spec file, the file … Ideally, I would like to just put all the font files within the BUILD folder under a directory structure like ./usr/share/fonts/ and then reference that within the %file section of the SPEC and let rpm do its magic. Parameterized macros include an options field, and perform argc/argv processing on white space separated tokens to the next newline. RPM spec files have several sections which allow packages to run code on installation and removal. The "Recipe" for creating an RPM package is a spec file. The spec file is the recipe we use to tell rpmbuild how to actually perform a build. This means you can’t really get a package’s .spec file — you need to extract the .spec information you want. During macro expansion, both flags and arguments are available as macros which are deleted … THE SPECFILE. The -f option is used to direct RPM to read the %files list from the named file. These bits of code are called scriptlets and are mostly used to update the running system with information from the package. To name the file, use the name of the package with the file extension .spec… A spec file is always part of any rpm. From document "Directives For the %files list":-f — Read the %files List From . RPM spec files have several sections which allow packages to run code on installation and removal. So when we extracted our src rpm, we also got httpd.spec file, we will copy the httpd.spec file to SPEC directory. We will need this to create rpm package with a new version. Spec files end in the ".spec" suffix and contain the package name, version, RPM revision number, steps to build, install, and clean a package, and a changelog. Probably I am missing or misunderstanding something here. In this section we will discuss how to create and modify a spec file. A spec file is basically a set of instructions on how to build the rpm package. Spec file is not scripting language, you still can use your own script file to create file list and feed the list to spec file.
