Coincidentally, I've been working on the same thing myself for the past several days. I succeeded in compiling Gem on OSX 10.12 with Pd 0.47.1 (64 bit), using an amalgam of these instructions:

Gem github wiki

GEM-dev mailing list

As seb noted, no quicktime film/video support, and I also get the extra dock icon & Pd crashing sometimes when I close my patch.

Having noticed this conversation the other day, I tried compiling Gem against Purr Data 2.3.1 using the same general method, but didn't get far at all. I didn't save the errors, but got a sense that it'd be much more involved than just adjusting paths to Pd-l2ork/Contents/Resources...

I haven't tried to compile the gmerlin plugin, but I have the imageJPEG plugin working, and I've spent many hours trying to get videoVLC working. There are several mailing list discussions which suggest that the problem might be with gem_videoVLC.so (perhaps not pointing to libvlc.5.dylib correctly, either needing editing or symlinking?).

I'm reaching the limits of my meager hacking abilities, but nonetheless it's pretty exciting to have Gem back up & running on 64 bit! I'm happy to join the cause if others are also interested in trying to work out the kinks in enabling the rest of the workaround plugins (gmerlin, videoVLC), and hopefully also find a way to get Gem working on Purr Data.

@maddynakedymaddy A bit hard to work out like this at a distance....

If you have put the "contents" of the 0.94-test3 folder in a folder called Gem inside the extra folder then you will need to put....... exactly....
C:/Program_Files_(x86)/Pd/extra/Gem/Gem

If you have put the 0.94-test3 folder in a folder called Gem inside the extra folder then you will need to put........ exactly.......
C:/Program_Files_(x86)/Pd/extra/Gem/0.94-test3/Gem

In both cases the last "Gem"..... /Gem loads the Gem.dll (the library) in the folder that contains it...... it is a bit confusing... and "abnormal"....

Spaces in names are not tolerated in Pd, and spaces are not tolerated in paths in Windows7 or previous versions....... Windows 10? I don't know?
Backslashes...... \ .... are dropped (ignored) in Pd..... they need to be forwards....... /
David.

@maddynakedymaddy Do you get these lines in terminal? or others? (obviously not the same paths though)

tried C:/Users/David/Desktop/dot/0.94-test3/Gem.dll and succeeded

GEM: Graphics Environment for Multimedia
GEM: ver: 0.93.CVS 
GEM: compiled: Sep 22 2014

GEM: compiled for MMX/SSE2 architecture
GEM: using SSE2 optimization
GEM: detected 8 CPUs
GEM: image loading support: QT SGI
GEM: image saving support: QT SGI

Probably you get others...... as it is not working.
What do you get?

You might simply need to to set startup preferences like this (again...... not "desktop/david"...put whatever your path is.....)
You need the complete path to the "Gem" within 0.94-test3. It is documented somewhere. "Gem" is the library, not the folder that contains Gem.dll ..... It must be Gem with a capital, and without the extension.
You don't need -noautopatch........ it is just one of my preferences.

@Balwyn I've follow your steps but still nothing this is what i got in the console:

Thx a lot,

Unfortunately there's another problem.The only Video I can load into pix_film seems to be with the following Codec:

All the other formats I tried didn't work. But I need to play Videos from different smartphones.

In the manuals I read it seems like it should be possible to play most formats which I can play back with VLC player.

How can I fix this problem?

Thx a lot!!!

Please help! Sooooo many hours trying to figure this out, should be simple I think but I'm not a sophisticated user of Linux.

The Gem objects appear properly when I open the windows, but whenever I try to open/create a gemwindow, it immediately crashes (however, it seems to respond when I change the data - for instance, I can see color changes when i make those changes, but again, the gem window crashes immediately...)

A possible solution lies here but haven't been able to get a response when I attempt to implement this

Why does Gem crash when creating the Gem-window? !

When I try to create a Gem-window, my X-server crashes (or worse)? btw, I am using Ubuntu/hoary with fglrx drivers.
quick

try setting the environment variable GEM_SINGLE_CONTEXT to 1
explanation

Gem establishes an (invisible) openGL-context at startup, even if no Gem-window is created yet. When you create the Gem-window, a 2nd openGL-context is used (which shares some properties with the invisible context).

For some reasons this seems to be not possible with some gfx-drivers (e.g. ATI's proprietary fglrx drivers) and some window-managers (i suspect compiz/beryll), leading to crashes of the X-server and/or system freezes.

The current workaround is to set the environment variable GEM_SINGLE_CONTEXT=1, which prevents this dual-context magic.
how?

if you are starting Pd from the bash, you can start Pd/Gem with GEM_SINGLE_CONTEXT=1 pd -lib Gem
on bash, you can also set this permanently by adding a the line export GEM_SINGLE_CONTEXT=1 to either ~/.bashrc (the bash-configuration file in your home-directory) or to /etc/bash.bashrc (to set it for all users)

"

• newer linux user but though I followed compiling instructions for installing Gem, it seems never to create a conf file.. when I open pd-extended in terminal, I get this message:

open: ./gem.conf: No such file or directory

any thoughts or input would be VERY APPRECIATED, thanks!

Hi, thought I'd post here even thought the thread is old before starting a new topic because my problem is exactly that as described here, though none of the suggestions have help and no one seems to have my exact error console output, which is as follows:

So I've added the word "gem" (with no quotes) to the Startup list, and the external library locations (whose paths can be seen in the above output) yet it doesn't work.

Any ideas? I've verified that both pd and gem are installed and at the lastest version. I'm using Ubuntu 11.10

GEM interactive GUI, evaluation so far

I tried to translate one of my setups, SliceJockey, to a GEM GUI. But by now, when the work is almost done, the setup is full of not-so-ideal workarounds and I must conclude that it worked just more straightforward with Tk.

I won't completely give up on GEM, because it is fairly well possible that audio and control procedures in SliceJockey are somehow 'tuned' to the Tk GUI because they were developed there, and a setup developed with GEM right from the start may work smooth.

Anyway, I've noticed some characteristics of GEM which are sort of incompatible with the notion of a general GUI framework. GEM is optimally suited for motion graphics and video manipulation. It is efficient where Tk is slow, when it comes to updating the screen. But the other way round is also true. Rendering of static information is in some cases much easier with Pd Tk than GEM. Some GEM bottlenecks:

• good quality text rendering (crossplatform, with [text2d]): way too expensive

• plotting of static arrays like sample waveform: cumbersome and expensive

• separate Pd instances required for GEM and audio patches

GEM aspects which I find *very* attractive for GUI purpose:

• GEM window with all it's content can be created at any size, and thus accommodated to screen size

• fairly easy to set up an x-y pad with multiple objects of any shape or size

• fairly easy to animate objects in response to audio data

• option to create pictogrammed control objects

Hey

Once again I'm back on vista. My brief journey to puredyne goes something like this.

from puredyne
partitioned new hard drive with 4 partitions 1-swap , 2 ext4 200Gib, 1 NTFS 200GB . Copied Vista to NTFS partition with gparted(started to do this with dd but with new Gibabits stuff I was skeered but hey a platter is a platter and a cluster is a cluster right). Actually there was a 5th partition in there which was the vista restoration partition but I eventually deleted it for obvious reasons.

Removed old drive ,
took machine to ethernet connection with internet,
booted to vista ,
installed Norton virus scanner - only 1 virus, 2 tracking cookies, and one gain trickler after over a year with no virus scanner, Thats pretty good and shows you can be selective about what you download and where you visit on the web and not get any viruses.

Was trying to get windows movie maker to work with mov codec which it doesnt.
Installed auto updates for the first and only time. this took about 3 hours and still needed to install service pack 1, 2. Aborted trying to update win movie maker

****Problem 1***** MS movie maker does not work with GEM mov video output codec.

Installed latest Nvidia drivers for vista.
Woohooo OpenGl hardware acceleration GEM works so much better in vista now.

*****Problem 2********ASIO for all does not allow 2 applications to run with audio and midi at the same time. If I wanted to run Widi and play my guitar so puredata can receive midi input from guitar ASIO will not allow it but ASIO for all is the only way I can get latency down so this would be feasible.

Got frustrated.

Installed fresh copy of puredyne onto 2nd ext4 partition.
ran puredata audio latency good with fresh install. gem video bad.

used synaptics to install nvidia drivers. v185 I think.
ran GEm error no opengl config.

downloaded gdeb , flash player, google chrome, nvidia drivers from nvidia site.
installed gdeb from terminal, flash and chrome from gdeb.
rebooted to log in as root and iunstalled nvidia drivers.

woohoo hardware acceleration for opengl

******problem 3************
gem works great but audio glitches with puredata window visible.
when only gem window is visible i can unaudioglitchily move the mouse around to control same parameters that would normaly be controled with sliders in pd window.

Seems like before i upgraded nvidia video drivers hw:do o whatever it is, was listed in JackD as realtek HD Audio, now it is listed as NVIDIA HD Audio.

So Gem works great but not when Pd window is open and I think my audio drivers were replaced with Nvidia.

I would really like to get back to my patch and stop wasting time on these operating systems and hardware configurations I thought in the last 15 years all this hardware acelleration and autodetection would be figured out but no all we got is rc.0, rc.01, rc.02, rc, etc...... instead of just rc.d.

Ok I'm getting an error when I exit puredyne that says pid file not found is jackd running. anyone know what that means?

Also does anyone have a keymap for gem keyboard for linux, windows and mac so I don't have to record them.

Any suggestions about what to do about my ASIO problems in windows?
Any suggestions about my audio driver in Linux?
Any suggestions about my GEM mov video / windows incompatibilities?

I can import the mov video and audio to SF Acid 3.0 and output a 2Gb avi then import it into windows movie maker but this is crazy to do for a 7 minute 12fps 320x240 video.

Ahhhhhhhhh!
Any suggestions are welcome!

PS I believe someone could rewrite puredata's audio and video interface in assembly language to control their hardware before figuring out how to get these operating systems to do it.

yup!

It's super weird.

but yeah, so far, I can only get 1200 1600 and higher. Maybe if I worked in YUV?
