[glsl_program] works fine.
Gem/examples/10.glsl/09 works fine. (get 0/1 from message gem_state so vertex and fragment shaders are loaded)

But i still get pd crash with libvlc.

[gemkeyname] and [gemkeyboard] work fine with object [gemwin] but not with abstraction [abstractions/gemwin].

Yep, there is conflict between libvlc and other libraries.

The problem seems to be [glsl_program]. An exemple patch is attached ;)

Yep.
But I also notice [gemframebuffer] with IntelHD doesn't like [format RGB32(.
For exemple, in Gem/examples/10.glsl/09... it is possible to change [format RGB32( to [format RGB( to have something working on IntelHD. Maybe it is possible to add a comment in the patch (or add a new message) to explain how to make this patch working on IntelHD ?

I just create a patch with :

[gemhead]
|
[route gem_state]
|
[print]

and there is no more 0/1 in pd console when you create or destroy gemwin.
On my side, i only use [loadbang] to load vertex/geometry/fragment shaders.

[gemkeyboard] doesn't work too.

PS : i just notice that i am working with Gem from http://github.com/umlaeute/Gem.
I will try with Gem from git://pd-gem.git.sourceforge.net/gitroot/pd-gem/Gem ...

that's by design.

no. [gemwin] and [gem*window] are *not* the same.

the design is obviously different from what you expect.

[gemdefaultwindow] (or rather it's underlying implementations like
[gemglxwindow] or [gemglutwindow]) is really just a very thin wrapper
around an openGL-context.
all it can do is to create/destroy an openGL-context (aka window), and
make that context the "current" one (so any openGL commands are
exectuted within this context).

it does a lot less than [gemwin], which handles viewpoints, rendering,...

short overview:

starting with Gem-0.94 (that is: current git), [gemwin] is now an
abstraction (found in abstractions/).
internally it uses [gemdefaultwindow] to create/destroy/switch-to
windows/contexts, which is just another abstraction that wraps the
actual implementation (e.g. [gemglfw3window]), but you really need the
entire [gemwin] abstraction to use Gem as you used to.

apart from separating platform-independent code (as found in the
[gemwin] abstraction) and platfrom-dependent code (the actual
[gem*window] backend), this also allows the user to change the
behaviour of [gemwin] without needing a compiler.

conclusion:
add abstractions/ to your path, so you have a proper [gemwin].
