[PD] [PD-announce] share-mem lib

Fri Nov 2 16:08:12 CET 2012

However, the "declare -path" won't make it _not_ work and will fix the
example if a 'user' downloads it without changing their Pd installation
(as someone like me would normally do.)  So I'd recommend the "-path" option
as the easier way to get started up.  Once correctly "installed", ideally,
it shouldn't need any declarations at all.

cheers

An alternative is to use [declare -lib share-mem], then it'll work wherever as long as share-mem is installed.  The downside there is that the library needs to be in the standard install location or the path in order for that to work.  For development, I often put a symlink in ~/pd-externals to the folder in SVN, then it works everywhere.
