I have MAIN.mk4 build file for make4ht. It is seen by
kpsewhich -all MAIN.mk4 There is only one copy of this file in the whole system. But when I use make4ht --shell-escape -ulm default -a warning -e MAIN.mk4 index.tex "mathjax,html" The file MAIN.mk4 is not found. I know this, since I have print statements in MAIN.mk4 which do not show. However, if I hardcode the path in the call, like this make4ht --shell-escape -ulm default -a warning -e /mnt/g/texmf/tex/latex/MAIN.mk4 index.tex "mathjax,html" Now it sees it, since I see the print statements on the terminal. I have thought that -e will find the build file if it is seen also by kpsewhich? make4ht --version says v0.4b Latest TL update. Linux OS. Thanks --Nasser
