Octave Packaging Guidelines
What is Octave?
The definition from website says:
"GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language."
If you are interested in packaging Octave packages, you should check here for upstream sources:
RPM macros
The following macros are defined in /etc/rpm/macros.octave in the octave 3.4.0 (Fedora 15+) package for help in packaging:
# Octave binary API provided
%octave_api %(octave-config -p API_VERSION || echo 0)}
# Octave Package Directories
%octshareprefix %{_datadir}/octave
%octprefix %{octshareprefix}/packages
%octarchprefix %{_libdir}/octave/packages
%octpkgdir %{octshareprefix}/%{octpkg}-%{version}
%octpkglibdir %{octarchprefix}/%{octpkg}-%{version}
# Run an octave command - quietly with no startup files
%octave_cmd()
# Build Source0 into a package tar file in a temporary location
%octave_pkg_build
# Install a package. We use the octave pkg install command to install the
# built package into the buildroot. We also put a note to prevent the root
# user from removing the package with the octave pkg uninstall command
%octave_pkg_install
# preun script - we need to remove our uninstall protection and perhaps
# run the package's own uninstall script.
%octave_pkg_preun
Octave packaging tips
Naming of Octave packages
Packages of Octave packages have their own naming scheme. They should take into account the upstream name of the package. This makes a package name format of octave-$NAME. When in doubt, use the name of the module that you type to import it in octave.
'''Examples: '''
octave-java (Octave package named java) octave-gsl (Octave package named gsl)
Limitations in the pkg function of octave (pkg.m) means that versioning of octave packages requires that the package version must have a MAJOR.MINOR.MICRO format. Failing to use this format results in octave not recognising binary package components in %prefix/libexec.
Updating the octave package database
Octave maintains a list of installed packages in /usr/share/octave/octave_packages that needs to be updated on package install and removal. This file is in an octave plain-text format.
The contents of the /usr/share/octave/packages/ directory are scanned for the follwing files when performing a pkg('rebuild') from within octave.
-
/usr/share/octave/packages/NAMEOFPACKAGE/packinfo/COPYING
-
/usr/share/octave/packages/NAMEOFPACKAGE/packinfo/DESCRIPTION
If these files are not present in any given NAMEOFPACKAGE directory, then octave will silently skip the folder and fail to index it correctly.
Octave will use the contents of octave_packages to modify its path at startup, allowing octave to find plugins.
Spec Templates for Octave packages
There are two types of Octave packages: arch-specific and noarch.
Arch specific Octave spec template
%global octpkg image
# Exclude .oct files from provides
%global __provides_exclude_from ^%{octpkglibdir}/.*\\.oct$
Name: octave-%{octpkg}

%description
The Octave-forge Image package provides functions for processing images. The
package also provides functions for feature extraction, image statistics,
spatial and geometric transformations, morphological operations, linear
filtering, and much more.
