Gem/gemglxwindow

Hello,
thanks for the answer, sorry i missed that.
things work lot's better now!!!
i still have few problem :
- when starting pd in the Gem/ folder, it start correctlly.
when starting pd in an other folder, pd segfault when loading gem_videoVLC
plugin
so, i just remove it : sudo rm /usr/local/lib/pd/extra/Gem/gem_videoVLC.*
- i did not try all example, but most work. i do however have some problem with
Gem/examples/10.glsl/05.multitexture_bis.pd
if i open and close this patch, pd segfault (even without opening a
rendering window). The patch did work.
- some other shader example did not render anything unless i configure optimus
to use the nvidia card. It's not a gem fault, just the intel HD and it's driver.
- gemwin use to send 1 / 0 when start / stop rendering. i sometime use this to
load shader, like in example Gem/examples/10.glsl/09... In this example, i have
to manually load the shader.
- gemmouse work, but not gemkeyname
thanks for all good work
cheers

hello,
i just tested the current Gem git. (i'm still using on ubuntu linux
14.04, intel hd4000)
gemwin did not create. Gem/gemdefaultwindow can be created. it use
gemglxwindow. (i have both gemglutwindow.pd_linux and
gemglxwindow.pd_linux in /usr/local/lib/pd/extra/Gem)
sending the create message on this object did create an empty
window. but sending "1" did not enable rendering, i only get :
gemglxwindow: no method for 'float'
so : why did gemdefaultwindow is not named gemwin?
that's by design.
(sould i just make a symlink?)
no. [gemwin] and [gem*window] are *not* the same.
more important : how can i enable rendering?
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].
