Hi Pablo,
I’m afraid that I cannot make latest from 2022.10.14 10:16 with LuaTeX.
I’m on Linux64.
I've got the same configuration and I'm getting the same results: $ context --luatex test.tex mtx-context | redirect luametatex -> luatex: luatex --luaonly "/opt/context/tex/texmf-linux-64/bin/mtxrun.lua" --script mtx-context --luatex test.tex --redirected mtxrun | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua' $ luatex '\relax' warning: /opt/context/tex/texmf/web2c/texmf.cnf:49: (kpathsea) No cnf value on line: OSFONTDIR =. This is LuaTeX, Version 1.15.1 (TeX Live 2023/dev) system commands enabled. kpathsea: Running mktexfmt luatex.fmt mktexfmt: No such file or directory I can't find the format file `luatex.fmt'! $ luatex -ini '\end' warning: /opt/context/tex/texmf/web2c/texmf.cnf:49: (kpathsea) No cnf value on line: OSFONTDIR =. This is LuaTeX, Version 1.15.1 (TeX Live 2023/dev) (INITEX) system commands enabled. No pages of output. Transcript written on texput.log. LuaMetaTeX works fine though. Thanks, -- Max
