Ubuntu 14.04 Script Error #2

Closed dawsbot closed 9 years ago

dawsbot commented 9 years ago

I am looking to work on the example as a developer application, but I getting several script errors while running the example with "python -m SimpleHTTPServer". I downloaded each and every one of the git repos detailed here, but after viewing the URL in my browser I am getting the following errors:

Uncaught Error: Script error for: SCENERY/Util/Color
Uncaught Error: Script error for: PHET_CORE/Platform
Uncaught Error: Script error for: SCENERY/display/webgl/colorTriangleBufferData

As a quick misspell check I changed SCENERY/util to SCENERY/Util, but this simply caused more bugs.

Screenshot of the browser error (attempted in both Chrome and Firefox): screenshot

Has this code been used before on Ubuntu 14.04?

Thank you for your time

Hi @dawsonbotsford, thanks for the problem report. None of our development staff is using Ubuntu for development at the moment, and it appears that both Windows and OSX is case insensitive:

http://apple.stackexchange.com/questions/22297/is-bash-in-osx-case-insensitive

HFS+ (the Mac filesystem) is usually configured to be case insensitive but case preserving. This means that the file system will consider foo and FoO to be the same, but when you create a new file it will remember which letters where capitalized and which were not.

All of the issues identified above look like case sensitivity issues. I'll work to commit fixes for them shortly, but since I don't have a case sensitive system to test on it will be difficult for me to iterate and find more of these problems (if they are masking more issues).

I have fixed the aforementioned casing problems in the above 2 commits. @dawsonbotsford can you pull the changes to joist and scenery and check to see if this was masking other downstream casing issues?

@samreid, those changes work. Assuming the following picture is the full vis you have made the entire software Linux compatable in a matter of moments! Thanks image

That looks perfect, thanks for testing! Closing.
