I'm using MacOs X Maverick with the latest MacTeX 2013 (updated 22/05/2014).

I'm getting this error error message :

(/usr/local/texlive/2013/../texmf-local/tex/gregoriotex/gregoriotex-signs.tex)
(/usr/local/texlive/2013/../texmf-local/tex/gregoriotex/gregoriotex-syllable.tex)

I'v searched on this site and found this topic : Compilation error with LuaLaTeX (luaotfload- database.lua)

I've tried every solutions given in that topic :

• delete font cache and run luaotfload-tool -vvv -u ==> successful, but I still get the error with lualatex
• downgrade luaotfload package and rerun luaotfload-tool -vvv -u ==> successful, but I still get the error with lualatex

I've checked that my luaotfload-database.lua is the patched one since this issue is well-known.

I still have the problem :

(/usr/local/texlive/2013/../texmf-local/tex/gregoriotex/gregoriotex-signs.tex)
(/usr/local/texlive/2013/../texmf-local/tex/gregoriotex/gregoriotex-syllable.tex)

MWE: Minimum working example, an acronym mentioned rather frequently on this site. Basically, a (possibly non-working) LaTeX document that starts with \documentclass and ends with \end{document} that generates the problem, or problems, that you're looking to fix. Without this information, we basically can't tell what actually gives rise to the error messages you report getting, making it rather difficult to provide a diagnosis, let alone prescribe a cure. –  Mico May 28 '14 at 14:27
