Hello,
I have updated open sesame and now i can't run my experiment,

Can someone help ?

Hi,

Does this error occur for all experiments with the xpyriment backend (such as the default template)?

Cheers,
Sebastiaan

oriane_g26

yes, this happened with xpyriment backend,

Daniel

Hmm, I've seen this before. What image type (jpg, ping, etc) are you trying to show? It could be that one of these libraries didn't get packaged correctly.

oriane_g26

i don't try to show any picture, i just use words directly written in block loop, and i use sketchpad to show them

sebastiaan

Based on the stacktrace, the problem occurs when scaling the Expyriment logo on initialization. In other words, I suspect this happens immediately when starting the experiment, and with all experiments that use the xpyriment backend (not just this one experiment). Is that right @oriane_g26?

@Daniel This is partly my fault, because after you fixed the libSDL_ttf issue I only checked whether it was possible to import Expyriment from the debug window. I should of course have checked more thoroughly.

In any case, I will roll back the Mac OS package on the download page until we're sure that this is not a general problem with the new Mac OS package, or (if it is, as I suspect) we've fixed it.

oriane_g26

yes you're right !

Daniel

Alright, I think I know what's causing this. I'm creating a new package as we speak and will upload it soon. Hopefully it will solve this problem.

Sebastiaan asked me to try my experiment with the new 3.1.5 version. So i did now.
Here is what i get on Mac. I do not know whether it is the same problem. What i know is that it does not work, so i will not update on my running computers

Cheers Stephan

Stopped

The experiment did not finish normally for the following reason:

After a slightly messy series of repacks and bugfixes, I think we're good. @Daniel packaged 3.1.6 for Mac OS, and it now works perfectly for me on an iMac running Mac OS Sierra (the latest version of the operating system). Thanks again Daniel!
