Hi,
i am trying to run patches containing Gem-objects in Pd-l2ork 2.4.6 Linux 64-bit
and get many "couldn't create" errors.

Starting PD it states:

libdir_loader: added 'Gem' to the global objectclass path

the folder
/extras/Gem/
exists

the /examples/ don't work
and renaming the Gem-objets with [Gem/objectname] doesn't work neither.

[gemwin] is successfully created,
but inside are all the broken objects.

here are two error-messages out of many similar ones, as an example:

 GLdefine GL_STENCIL_BUFFER_BIT
... couldn't create
 GEMglMatrixMode GL_MODELVIEW
... couldn't create

Did someone make it work?

Oops, sorry-- don't type the brackets [ and ] in the object box. Just the path.

of course I know, I did so. But I will try again

starting pd without flags:

objectclass path
/usr/lib/pd-l2ork/extra/Gem/Gem
... couldn't create

with flags like this:
pd-l2ork -nrt -noprefs -nostdpath

the same output as without flags

Also-- what distro are you running?

lol
Puppy Linux Xenial-64

didn't have any problems yet.

.
As far as I know there is no permission-issue:

Puppy-Linux doesn't use Sudo or anything.
I am root and there is a special "Spot"-folder, for online applications running as spot, with less permissions.
Pd is not in spot, and the Gem files neither. So spot has nothing to do with this.
I assume, that there are no permission-conflicts.

.
What should happen creating the objects containing the paths?
Should I try installing the newer Purr Data version?? Or Gem?

.
Could be the 64-bit an issue?
I read in other threads Gem was made for 32-bit?
Do you have it running with 64-bit?

from http://puppylinux.org/wikka/XenialPup

"
Xenialpup 7.5 uses Ubuntu 16.04 Xenial Xerus packages and includes the bugfixes and improvements from the Woof CE build system. It is compatible with Ubuntu 16.04 packages. The Linux kernel version is [...] 4.9.58 for the 64-bit build.
"

Do you assume that the distro is the issue?

Could someone please give me a hint, what could be the problem with Gem?
Other libraries are working.

Is Gem running on your 64-bit Linux-distro with Purr-Data?

You should see some messages to the console about Gem loading various plugins.

I'd definitely try installing a newer version of Purr Data.

Ok, here's another test...

1. cd /usr/lib/pd-l2ork/extra/Gem
2. pd-l2ork -noprefs -nostdpath -nrt -verbose
3. In an object box type Gem
4. Instantiate the object

What gets printed to the Pd console?

libftgl is missing?

Try sudo apt-get install libftgl2

Ok, here in Puppy-Linux apt-get is not installed.
Now I installed libftgl2_2.1.3 successfully with the package manager.

Doing the same as before
[Gem] creates! Yes!

There are some more libs missing, maybe I should install them too?

All the examples of Gem seem to work now!
Even the teapod and openGL stuff.

And my final patches, also work. So nice!

Now I will review what those flags actually do:
https://puredata.info/docs/faq/commandline

But I am wondering, if I was lucky, that Gem is programmed for printing messages in the commandline and other non-working libraries probably won't do so?

Thank you so much

@lacuna You can always use the "-verbose" flag to see what's happening.

But I would suggest only using that flag with the "-noprefs" and "-nostdpath" flags. Then navigate to the relevant directory and try loading the relevant library.

Otherwise you'll get lots of verbose load messages which make it difficult to figure out what's relevant.
