Could not create window

[godeye]

when it convert.it shows

root@debian:/srv/stlthumb# stlthumb che.stl che.png 500 500 che.stl: 707091 Could not create window

what cause this?

[kolrabi]

Are you running it from the console? Right now it needs a connection to a windowing system to create a hidden window to do the rendering in.

[godeye]

yes i am running from console. could we use command line to use it in other script such as php/python?

[kolrabi]

I just committed a change that allows to use osmesa and EGL support. Add "-DUSE_API=OSMESA" (or "-DUSE_API=EGL" respectively) to your cmake arguments to enable it. Either should work from the console or a script. EGL might even be hardware accelerated. Can you try it out to see if that works for you?

[kolrabi]

Hmm... does it work if you use osmesa instead?

[godeye]

need gpu supported? i test it in my linode web server,and failed.

[kolrabi]

The osmesa renderer should work without a GPU, but I never tested it in a server environment.
