These two fonts are in /usr/share/fonts/OTF. In that directory they are listed in fonts.dir. I want to use simplefonts to use Minion as the base font. I ran the various commands described in the Wiki page: http://wiki.contextgarden.net/Fonts_in_LuaTeX and got the two fonts listed in the font database. I put the following in my MKIV context file: ... \usemodule[simplefonts] % load the module \setmainfont[minionproregular] % %\whitespace[line] \usetypescript[serif,sans][hanging][pure] \setupalign[hanging] \setupbodyfont[minionproregular,14pt] ... Now I get a new error message: ------------------------- mtx-context.lua:675: attempt to call field 'locate_format' (a nil value) Any suggestions? -- John Culleton Wexford Press "Create Book Covers with Scribus" http://www.booklocker.com/books/4055.html
