Hi all, Following nice reports I read on the list as well as the mag-12 instructions I installed a context minimal linux distribution and lua-5.1.2. After everything seemed ok I lauch a compilation of this test-file (found on the wiki): % engine=luatex \starttext Hello from luatex \blank LUA \startlua a = 1.5 b = 1.8 c = a*b tex.print(c) \stoplua \stoptext But no pdf file appears, and here are some (hopefully) relevant parts of the compilation message: TeXExec | unable to fix backend map path TeXExec | running: luatools --fmt=cont-en test.tex LuaTools | using format name /cont-en.fmt LuaTools | no luc/lua with name /cont-en LuaTools | LuaTools | runtime: 0.09 seconds TeXUtil | unable to locate test.tui I do have cont-en.luc and cont-en.lua! tia -- Jean
