[erild]

All the shader files are raising Syntax error in the javascript console

Some more info please!
platform? Browser? gfx hw?
Were you running meshlabjs from the released version on the web (e.g. from www.meshlabjs.net ) or the developement/master branch from you own local server?

I am running from the master branch on my local server, no problem on the released version.
The issue seems to be only in firefox on windows. There doesn't seem to be any issue when running it with chromium ( Windows or debian ) nor with opera.

Firefox has a number of issues with jquery.ui (see https://bugs.jquery.com/ticket/9805 ) but they do not prevent meshlabjs from working. Moreover I do not see the shader error you refer to. Please try to be as exhaustive as possible.
