gem for Debian
======================

Usage:


The preferred way to use Pd with Gem is to add the following object to
each of your patches/abstractions that use a Gem object:

    [declare -lib Gem]



Legacy ways include:

to start Pd with Gem support, issue the command (without the '%' sign)

```
pd -path /usr/lib/pd/extra/Gem -lib Gem
```

OR

use the provided script instead of directly starting Pd:

```
/usr/bin/pd-gem
```

OR

start Pd
- navigate to "File->Path..." and add "/usr/lib/pd/extra/Gem" to the
  list of search-paths
- click OK
- navigate to "File->Startup..." and add "Gem" to the list of binaries
  to be loaded
- click "Apply" and "Save all settings"



selecting a windowing backend
-----------------------------

[gemwin] is backed by one of multiple windowing backends to choose from:
- GLX
- GLFW3
- GLUT
- SDL

In order to change the backend Gem is using, run the following:

```
sudo update-alternatives --config gemdefaultwindow.pd
```

This will ask you, which backend you want to use.
After you made your choice, restart Pd/Gem.



KNOWN PROBLEMS
--------------

1. crashes when creating/destroying a window:
Gem relies on being able to establish one or more openGL contexts.
By default it creates 2 contexts on startup, which might lead to
unexpected behaviour (e.g. crashes when closing the Gem-window) on
some systems (depending on gfx-card/driver).
if this happens to you, please try setting the environment variable
"GEM_SINGLE_CONTEXT" to "1" before starting Pd/Gem.
e.g. start Pd/Gem with:
% GEM_SINGLE_CONTEXT=1 pd -path /usr/lib/pd/extra/Gem -lib Gem
