Introduction

The bulk build framework allows a pkgsrc user to create binary packages for all source packages at once, so that they can be used without the need to compile everything on each machine.

Preparation

You need:

• A copy of pkgsrc (may be read-only),
• About 10 GB disk space for the distfiles,
• About 5 GB disk space for the binary packages,
• About 5 GB disk space for the log files,
• Much time (plan at least one week).

A bulk build works as follows:

• First, a database of all the pkgsrc packages is generated. For each package, it contains the package name, package version and the dependencies on other packages.
• Second, all packages are ordered so that the packages without any dependencies are built first, and then the more complicated packages follow.
• Each package from the above sorted list is built.
• After building all packages, a report is generated.

You need some distinct directories to do a bulk build:

• PKGSRCDIR (read-only) contains the pkgsrc files,
• DISTDIR (read-write) contains the distfiles,
• BULKFILESDIR (read-write) contains the bulk database and the log files,
• REPORTS_DIR (read-write) contains the bulk reports.
