SlackBuild for gpsd

There's recently been a long running thread in which xj25vm has explored the possibilities of getting gpsd to start on demand in Slackware, both when USB GPS devices are hotplugged (plugged into an already booted system) and when coldplugged (discovered by the system at boot).

The core difficulty to be overcome was that the gpsd daemon wants to read from a control socket which is created on the fly by a helper when the hotplugged or coldplugged device triggers an action in udev....

Notes on using LFS Chapter 5 to build a Slackware toolchain

Posted 10-13-2010 at 02:31 PM by 55020
Updated 10-13-2010 at 05:43 PM by 55020 (Doh! Right at the end, should be 'find $LFS...')

This is a brief set of notes on bootstrapping a self-hosting Slackware toolchain, using the process described in Chapter 5 of the LFS Book. Future notes will cover LFS Chapter 6, and then the rest of Slackware (or some of it, anyway).

The motivation for doing this arises out of a number of recent threads on the LQ Forum, but it's also just a generally cool thing to do.

Note that my host system is Slackware64-current. The target system is Slackware64-13.1. I also...

QGIS and GDAL SlackBuilds, again

Posted 08-03-2010 at 07:04 AM by 55020

Note that there is a new dependency. You need to install QWT (yes, SBo has a SlackBuild for that) before building the new version of QGIS. Well, you don't absolutely have to have QWT, but if you don't have QWT there will be reduced functionality in QGIS - for example, the new Live GPS Tracking will be missing.

SlackBuilds for qgis and gdal

Posted 06-29-2010 at 07:00 AM by 55020

Here's some news on two of the SlackBuilds I maintain at


It appears that the update of SIP in Slackware 13.1 (which occurred quite late in the -current cycle) exposed some breakage in the qgis build system. The consequence is that the current SBo-13.1 "BUILD=1" qgis-1.4.0 script builds without Python support. Unfortunately this means that a lot of qgis plugin functionality is disabled.

The problem is known upstream....
