I tried creating a package based on the tar.bz2 pd-ext installer from Hans-Christoph Steiner and ran into the following errormessage(s) when starting pd afterwards:

/usr/local/lib/pd/extra/Gem.pd_linux: libmpeg.so.1: cannot open shared object file: No such file or directory
Gem: can't load library
PDP: pure data packet version 0.12.5-darcs
PiDiP : additional video processing objects for PDP : version 0.12.20 ( ydegoyon@free.fr )

pdp_text : severe error : could not load default font : no rendering !!!
pdp_qtext : severe error : could not load default font : no rendering !!!
pdp_colorgrid: version 0.4, written by Yves Degoyon (ydegoyon@free.fr) & Lluis Gomez i Bigorda (lluis@artefacte.org)

The first error should be solved by installing some missing packages:

Code: Select all

apt-get install libmpeg1 libmpeg3-1 libmagick9 libmagick++9c2a

The rest is about a font being in the wrong directory.

I tried to load Ian Smith-Heister's Lude patch from 0x09.com, using pdext. This is what I got:

tk scaling is 1.04285347703
Warning: no LADSPA_PATH, assuming /usr/lib/ladspa:/usr/local/lib/ladspa
pd_gui: pd process exited
Segmentation fault

Using gdb, I found out that the segfault came from the pd-extra "flatspace":

Warning: no LADSPA_PATH, assuming /usr/lib/ladspa:/usr/local/lib/ladspa
(no debugging symbols found)

Program received signal SIGSEGV, Segmentation fault.

After removing (renaming) the directory flatspace, I was able to load the patch. It's still not working properly, but at least it loads. I gotta check my LADSPA settings on this system.
