ccby.pdf not found

If texlive 2020 is installed with all packages as eg in all Mac installations, loading of the classes fails. I did not notice this before since I had ./langsci// in my TEXINPUTS.

This is what a grep for langsci reveals:

grep langsci check-germanic.log

The result is that compilation fails:

The following helps assuming a csh:

setenv TEXINPUTS ./langsci//:${TEXINPUTS}

I removed the langsci installation to not load this stuff but then latex does not find langsci-basic since it is in ./langsci and not in the standard texpath.

\usepackage{langsci-basic}

OK. Here is what is going on:

\newcommand{\ccby}{CC-BY}
\newcommand{\ccbynd}{CC-BY-ND}

\fi

The pdfs are in a subdirectory named unchanged. Without the path specification

setenv TEXINPUTS ${TEXINPUTS}:./langsci//:

LaTeX does not find the graphics. I guess if everything has to be flat, you have to move these files up into the main directory of the langsci class.

Copying ccby.pdf into the project directory fixes this. I have learned that this is the normal setup now.
