Some time ago I had a problem with the fonts when generating the format, which I posted here. New versions didn't solve it, I always get the annoying Could not load ec-lmr12.tfm. Inexistent or bad font file, or something like that. I decided to compile and debug LuateX myself. Something worth indeed if I ever plan to become a developper. It was the first time I tangled something. I saw a luatangle.web (if my memory does not betray me), so I started tangling that, but I get pascal code, and I don't have a pascal compiler. I haven't had time ever since, so I simply stopped. Is there a way of generating c-source, or will I have to wait to September or so? If there is one, even though I am a programer a step-by-step explanation will be very wellcome. Tanks, --Javier A.
