Comment (by christsc@…):

 Replying to [comment:2 mojca@…]:
 > See also #41694, #30785 and possibly others. It seems that `getline` is
 not available on 10.6 and earlier, so the upstream project needs to take
 that into account and be fixed accordingly.

 Yes, the problem (that I was not aware of) is all over the place. See also

 -getline-on-mac-osx
 biosig has a getline implementation for win32 that we could make use of. I
 will try to add that to the cmake file.

 > If you want to make `stimfit` work on 10.6 faster than you can debug, it
 might be best bet to only make `+biosig` default (or maybe even only
 available) on 10.7 and later until you resolve the problem with `getline`.

 If the getline fix isn't straightforward I'll do that.
