cadabra2-gtk freezes #128

Closed suhr closed 4 years ago

suhr commented 5 years ago

How to reproduce:

  1. Open cadabra2-gtk
  2. Run { a, b, c, d }::Indices; in a cell

Probably related to latex output, since cadabra2 repl does not freeze. If pdflatex is not installed, cadabra2-gtk does not freeze.

OS: NixOS (using this derivative)

Probably has some oddball pdflatex installation, or a weird dvipng or something like that. I will try to have a look at it at some point, but I am very short on spare time at the moment. So you may get a quicker result by trying to build from source, then I can at least guide you with some debugging instructions.

I actually built Cadabra from sources using Nix.

The issue may be related to the fact that NixOS stores everything in non-standard paths. But the problem is, cadabra2-gtk produces no output, so it's not clear what is going on.

I am closing this for now due to inactivity; if it is still an issue with the current version, feel free to re-open, but please provide some more details (e.g. running cadabra2-gtk inside a debugger and giving a backtrace when the freeze occurs). Thanks for your input.
