Hi all, until now I have been using a 32bit system, but 2 days ago I installed a
brand new ubuntu '9.10' 64 bit. (And I want to keep it, this '9.10' 64
bit seems to me faster than '8.04' 32 bit)As Pd-extended for x86_64 is not auto-builded, I have some questions
about building a debian package :
- is there a document describing the SVN directory structure ?
nothing clear for the svn itself, but its fairly self explanitory (most externals folders have their own readme/info)..
for the extended buildsystem look here: http://puredata.info/docs/developer/PdExtendedBuildSystem and http://puredata.info/docs/developer/Debian
- what are the differences between 'pd-extended' and 'pd-vanilla loading
all externals' ?
pd-extended is a patched version of pd, so it has some minor differences in operation - the externals should not be drastically effected regardless of the build target. some more low level ones maybe (toxy / iemguts)
- what is the simpliest way to build pd-extended (a kind of 'nightly
build @ home') to produce a beautiful .deb package for x86_64
you can reproduce the autobuild fairly easily without too much hastle.
- what is the simpliest way to build pd-'extended'-gui-rewrite for x86_64
x86_64 will not be any different to x86, and the gui-rewrite uses autotools, so it will work this out for you.
- is there a simple way to have and manage differents pd (vanilla,
extended, gui-rewrite) with differents versions on the same computer ?
just compile without installing.. and launch pd from the command line using ./pd or something similar, for something more sophisticated choose a different install target for each build and build a script that chooses version at /usr/bin/pd
Some informations about what I would like to do :
- in fact I think I dont really need the whole pd-extended thing as I
often only use Gem with few (5, 6) others externals...
extended is mostly overkill if you know what you are wanting, and if you only use a handful of extra objects then maintain by hand.. it will take a lot of the pain out of the process.
- but it can be very nice to try and be able to use ANY of the external
included in the svn (I'm always in a learning process)
it is nice, but if you need them, and need them badly you will find them and install them. otherwise you could attempt to use some extended binaries with a 32bit chroot account, then you can 'try before you buy'!
- I would like to use the latest sources, nightly build was just fine
for me on 32bit
better anyhow, the latest stable candidate of extended is not designed for 64bit and needs to be heavily patched.
- but I also need to have a method to build a stable pd-extended release
if the latests sources give me pd crashes (I do Audio/Video live shows
and performance and stability are very important on scene...)
if you seriously want reliability then make a 32bit partition and install 32bit ubuntu 9.0 (or better still try an older more tested version of ubuntu) besides a lot of array based objects that have not been thoroughly ported to 64bit, 64bit pd is not propperly tested and needs a bit more time and attention. for performance stability stick with the tried and tested approach.
voila! any suggestion is welcome best regards, pierre
good luck.. if you seriously want to build for ubuntu 9.0 x86_64, be prepared for a bit of frustration.. heres some extra reading - albeit out of date:
