It seems I forgot to attach the log. Here it is.

Can you post your source file?

It looks like subject version 1 has no questions at all: is this the case?

Here is the source file.

You did'nt have errors while preparing documents?
With my setup your source file is not compiling: \AMCboxDimensions has to be called after \begin{document}.

That is strange. All of my AMC .tex files in the past have had \AMCboxDimensions before \begin{document} (that was before I installed AMC-1.3) . And if I move it after, I get the same error.

I will keep searching.

I have reproduced the error on the simple example from the documentation.

It seems that \AMCboxDimensions has to be called after \begin{document} since the storebox package option has been added, between versions 1.2.1 and 1.3.0.
Can you try a full test cycle with your source file with this correction, and report the issues?

I have reproduced the error on the simple example from the documentation.

Ok. Can you run a full test cycle (new project, etc.) in debugging mode with this sample and post the produced log file?

I uninstalled AMC and reinstalled AMC like this:

$ sudo port uninstall auto-multiple-choice
$ sudo port selfupdate
$ sudo port upgrade outdated
$ sude port install auto-multiple-choice

Then I re-ran the marking process on my test-amc.tex file. I got the same error—debug log is attached.

There were a few hundred thousand lines of this:

GLib-WARNING **: poll(2) failed due to: Bad file descriptor. at /opt/local/lib/perl5/vendor_perl/5.26/Gtk3.pm line 546.

Then I noticed you wanted a debug log starting from new project. So I tried that. This time when I got to the marking stage, the program hung up and the log file kept filling up with those same GLib warnings. I shut it down when the log file grew beyond 3 GB.

I'm leaving work now but I'll look more into this later. I may need to reinstall an older version of AMC for the time being.

So I have installed the from macports Portfile prior to the 1.3.0 tag (03ba81b942565a3a4812c7c9c4ce8331527edf94), and I was able to get it working again. Just like before, I had to replace the use encoding "utf8" lines with use utf8, but after that it works just before I upgraded to 1.3.

from macports Portfile prior to the 1.3.0 tag

Which revision is working exactly?

GLib-WARNING **: poll(2) failed

Maybe this is related to notification. Is Edit/Preferences/Display/Notifications/Desktop notifications checked? If yes, can you try the same with this option unchecked to see if the poll(2) failed lines disappear? However this does not seem related with your problem, so I'm afraid this won't fix it.

In the Data capture tab, do you have a message that counts some unrecognized scans? If so, click Look at scans, and then Preprocess, and post a screenshot of the window.

I'm not quite sure how to answer that question. I followed the instructions from MacPorts on how to install an older Portfile . I checked out the macports repository with the Portfile just prior to the one labeled as 1.3.0:

https://github.com/macports/macports-ports/blob/a82a684b671a52c83fe6608c4f530ddf82fe8e5f/x11/auto-multiple-choice/Portfile

That one has version 1.2.1 and revision 8 in it. I don't know what revision of AMC's repository that refers to, though. Browsing the repo I couldn't find any connection to the version/revision in the Portfile.

I have quizzes to administer/grade today and tomorrow. Later this week I will reinstall the up-to-date Portfile and run the other checks you requested.

OK. That's 1.2.1 (hg:cb5cf75697e1).

Hi !

I also experimented this nightmare,

That wasn't happening before. I cut all but two of them out of the log file to keep the size down.

Today, simply updating port solved the problem:
$ sudo port selfupdate
$ sudo port upgrade outdated

:-)

I also face the << Can't call method "set_type... >> problem, and so far, I don't know how I'm supposed to fix the problem. I have added the AMCBoxDimensions after the begin{document}, but it does not fix the issue. I have also removed the occurrence before the begin{document}, but it fixed nothing.

I'm fully up-to-date on MacPorts.

The exam was made, I have the scans, and I'm very afraid to lose the compiled documents... What am I supposed to do? I can provide logs, but I doubt they would defer.

I recently updated my macos to High Sierra, and with it updated MacPorts. But I still got this issue. In fact, when I googled the error, I came back to this post of mine, which I had forgotten!

So far the only workaround for me, has been to revert back to 1.2.1.

Can you (both) provide your source file, and the log file produced for all steps from preparing documents to marking, in a new project, with one or two scans?

@Matthew: Thanks, I managed to install and run the previous version of AMC and complete my grading (Alexis, thanks for not having changed the file formats!):

cd /tmp
git clone --single-branch https://github.com/macports/macports-ports.git
cd macports-ports
git co a82a684b671a52c83fe6608c4f530ddf82fe8e5f
cd x11/auto-multiple-choice
sudo port deactivate auto-multiple-choice
sudo port -n install  # -n to avoid updating opencv, which fails today
sudo perl -pi -e "s{use encoding .utf-?8.;}{use utf8;}" /opt/local/lib/AMC/perl/*.pl

@Alexis: Can't do that right now (my tex file runs many usepackage that I would need to compile first), but I will try to provide something asap.

I am still stuck on this error in AMC 1.3. I've created a small project using the simple example from the documentation. The compressed project, with the debug log included, is in a zip file. I tried to upload it but it seems too big; I'll try to share it with this link: [[https://nyu.box.com/s/duzb7to6ursn66p2fqsjvisaaymzd89f]].

Matthew: what is the version of /Users/matthew/Library/texmf/tex/latex/AMC/automultiplechoice.sty (you can find it at the beginning of the file)?

1.2.1, I guess? Here is the file header.

I saw a warning that I should use the up-to-date style file. Where is that normally installed?

Yes!

Where is that normally installed?

With MacPorts… I don't know exactly. Can you try the following command (although I'm not sure if the locate command is installed on macosx)?

locate automultiplechoice.sty
