I am using pd 0.47-1 in 64 bit windows 10 I have downloaded the gem and copied it into the pd installation file but somehow whenever i am trying to create a gemwin object the console window is showing couldn't create ,
have i got the path wrong please suggest

@maddynakedymaddy I could be wrong of course......
Gem is still 32bit as a stable official release, and so incompatible with 64bit Pd. https://puredata.info/downloads/gem/releases/0.93.3

There is a 64bit version here...... https://github.com/avilleret/Gem/releases/
0.94-test3.zip

I have that working and stable in windows 7 with Pd 0.47.1 64bit.
I had to copy the contents of the QT folder into the 0.94-test3 folder.
I set Pd to find the library using the -lib startup flag, but I imagine any method will work.

Some externals are missing, and I have not tried as yet to bring them in from an older version of Gem, as they are 32-bit and I am certain that they will not work.
But the essentials work well.
You might need Quicktime...... I don't know as I had it installed already. Maybe not, as the .dll's are in the package.
You might be missing a .dll in the series....... "msvcr90.dll" "msvcr110.dll" etc. in win10.... uncertain.

You might need to update your video card drivers in widows10 to get OpenGl working properly. Microsoft tried to move entirely to DirectX..... and you can thank the gaming community if your GPU manufacturer has maintained OpenGl support!!
I hope that helps,
David.

thanks a lot i will try it

i have downloaded the 0.94-test3.zip and have copied the contents into the pd folder installed in c drive
but still not working
i did go to preferences- statup -and then typed 0.94-test3 but still couldn't create the gemwin object.
please suggest

@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.

David.

see my console window is entirely blank
after going to preferences and putting startup the C:\Program Files (x86)\Pd\extra\Gem
I am getting an error message-
consistency check failed: sys_decodedialog: {+C:Program+Files+(x86)PdextraGem}
consistency check failed: sys_decodedialog: {+C:Program+Files+(x86)PdextraGem}
in the console window
Is it that I not being able to ascertain the path tp gem library
what is the the method to get the path ?

@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.

finally it has worked
thank you very much
can I ask a naive question
how did you got the path-
C:/Program_Files_(x86)/Pd/extra/Gem/0.94-test3/Gem
have you gone to preference -path and from that -by doing that I got this-C:/Program Files (x86)/Pd/extra/Gem/0.94-test3 -but how you arrived at the specific path you suggested me with the underscore and the last Gem word.
sorry for my lack of knowledge in this regard I just trying to get a better grasp so that I can troubleshoot later

Sorry but still thr is one moreprblm that needs to be solved
inthe console window I have a error message:

GEM: unable to find Gem's abstractions
GEM: please add path to 'Gem-meta.pd' to your search-path!

and therefore the square circle and other graphic objects are not loading i suppose
how do I solve this

srry i understand this is becoming bothersome bu I deceided to uninstall all my pd contents and load afresh
I have again downloaded PD 0.47.1
put the Gem folder from Gem-0.93.3 into the extra folder of Pd installation file and iside the Gem folder I have put the 0.94-test3 folder
now after putting the path in the start up i am getting his message in the conole window:

C:/Program_Files_(x86)/Pd/extra/Gem/0.94-test3/Gem: can't load library

so? whr am I going wrong now

@maddynakedymaddy I think 093.3 is 32bit again..... so it will not work....... but I am unsure.
As you say, many externals will not work with 64-bit 0.94-test3 as they have not been written into 64-bit versions.
You will have to go back to a 32-bit version of vanilla if you want the whole package......
It is not certain that the Gem abstractions will ever work in 64-bit...... we can only hope!
I am pretty sure that unlike the latest mac osx, Windows will still run 32-bit programs.
David.

@whale-av All now working correctly..... see.....

and with Gem abstractions and Help working.......

@maddynakedymaddy

On my Windows 8 machine with the 32 bit version of Pd and 32 bit version of GEM I was seeing the "can't load library" message from GEM. The only thing that worked for me was when I added msvcr71.dll to the pd\bin folder. I found this mentioned on the Sourceforge forum for pd-gem in response to someone using Windows 10. . The person there said to put the dll in C:\windows\system but I tried it in [...]\pd\bin first and it worked. I had to download the dll from an online dll repository.

I realize this is an old thread but for others like me who had this problem this might help. Good luck!
