The usual reply to myself kind of thing.<br>I've just tested an earlier pd-extended package, with GEM 0.91.3 (that's the one working in my Mac), and the problem persists.<br><br>When I create a "pool" instance and open the help patch and then try to close it (this is the fastest way to test, since it produces the same output as putting a fid_class object into the patch), this is what I get at the terminal console:<br>

Greetings.<br><br>This is my first mail sent to the pd-list, that I've used often as a resource to solve my Pd problems.<br>Thomas Grill, the author of "pool" and all the other "flext" goodness, such as the xsample externals recommended asking help here, since the problem I'm facing is somewhat specific.<br>
I use Pd-extended 0.41.4 on my MacBook as my main programming environment and I'm developing an installation project that uses a tangible interface and fiducials. For better tracking and management of the fiducials, I'm using JY Gratius' abstractions, that require "pool". No problem on my Mac, but the deployment of the installation has to be done with a Linux machine, and now I'm facing some strange issues. The available Pd-extended packages for recent Linux distributions are 0.42.5-rc5 and they seem to work just fine (I'm trying out Ubuntu and Ubuntu Studio 9.10 and 10.04), but whenever I try to use the pool object (directly, or via the fid_class object from fid_abs), PureData freezes.<br>
I've launch it via terminal with the double verbose option and I get a lot of jibberish (I'm really a newbie when it comes to Linux) and some of the error I got point in the direction of Gem. Some even pointed to early discussions here about Gem versions and flext externals and problems with file or command name replacements (sorry but I can't find the link, now...).<br>
I've made a simple test, following one of Grill's suggestions here on the mailing list of testing on Pd-vanilla, and the fact is that when I disable GEM, "pool" works just fine. But I need GEM and pool working together, as they do on my Mac.<br>
Is this a version problem? Does the new Gem "breaks" "pool" and/or other flext objects? Is it a Linux issue?<br>Can anyone point me at the right direction when it comes to having a stable Pd-extended on Linux with externals such as "pool"?<br>
