Hi,

I am trying to install woo from window subsystem linux, however until step python3 woo-install.py and encountered the error as shown:

Do you have any idea how to solve this?

Oh, that is an error in the script. I just commited a fix to github, please try with the newest version. Could not test much.

Hi Vaclav,

I now have ubuntu on my pc. After installation, I open woo, the simulation runs normally but whenever I open 3D scene, the software shows error and shut down the program. Do you have any idea? I actually had the same problem when installed YADE once.

Is that under Windows (in WLS) or in standalone Ubuntu installation? Either way, try to run woo with "LIBGLALWAYSSOFTWARE=1 woo" which will force software rendering (without acceleration), that way you will see where is the problem. HTH, Vaclav

Hi Vaclav,

Its Ubuntu not WLS. Sorry I dont understand what you meant by run woo with LIBGLALWAYSSOFTWARE=1 woo. I tried to run it as typing in the terminal but the problem is not fixed. I will try with other laptop to see if the problem persists. But thank so much for your support!

I also tried to install it on my department's server (debian OS ) but also encountered the problem (some files are not found). Are the commands

sudo apt-get update
sudo apt-get install python3-woo

only for ubuntu ?
(sorry for confusing you with many installation from different OS)
Kind regards,
Giao

His, sorry for the mess about packaging. The best is to use source - the same script scripts/woo-install.py will install on Ubuntu for you, plus you can update very easily (woo -RR and it's done). Debian's packages ale lagging behind, they have not updated those in a while, and I think ubuntu packages in the woo-daily ppa might be broken as well. I will try to look at that as soon as I can. But the source is the best. Cheers, v.

The LIBGLALWAYSSOFTWARE switches off 3d acceleration for the program. So you type LIBGLALWAYSSOFTWARE=1 woo (enter) and see if it still crashes.

Hi Vaclav,

The ubuntu now works when I tried to compile it on different computer. Thanks for your help. Please let me know if you have any further plan for the Debian's package.

Best regards,
Giao

Package maintenance is quite difficult, especially for evolving code. Then it takes months till the newer version gets to users; the PPA is quicker, but mut also be maintained. If you can stick to the source, better for you. I will let you know if something changes with packaging.

PS please make sure you use python3 (or slowly switch over - not a big change for scripts, mostly changing print a to print(a)), woo will not run on python2 forever (python2 itself is considered deprecated for about 5 years now).
