[OS X TeX] dvisvgm and ghostscript

[Ettore Aldrovandi]

I’m baffled too. I think I have a possible explanation for the first error, but not the second, reproducing Dick’s exact command line.

For what is worth: apparently dvisvgm needs to be told the location of ghostscript’s dylib. This happens by using the command line flag —libgs or setting the env variable LIBGS (the former overrides the latter). Also apparently dvisvgm does not find libgs.dylib by itself if not told in one of those two ways. Now, at the beginning, if the variable LIBGS, although set in .bash_profile was not picked up, it would have explained the failure, with the caveat that the error message was different. 

Just for clarification, Terminal does not run a login shell, unless set in its preferences. 

But all this does not explain the error once dvisvgm is run with the correct path put on the command line via —libgs. 

Most of those dylib files are actually symlinks. Is is it possible there’s a problem there? Maybe something went wrong during installation? This is what I have, but I installed ghostscript differently:

albemuth:~/tmp> ls -l /opt/brw/Cellar/ghostscript/9.53.3/lib 
total 26584
-r--r--r--  1 ealdrov  wheel  13610904 Oct  2 07:59 libgs.9.53.dylib
lrwxr-xr-x  1 ealdrov  wheel        16 Oct  2 07:59 libgs.9.dylib@ -> libgs.9.53.dylib
lrwxr-xr-x  1 ealdrov  wheel        16 Oct  2 07:59 libgs.dylib@ -> libgs.9.53.dylib
