Many thanks to those who answered my question on jpeg2ps. The problem was very trivial. Since I found no gzipped-tarred file, I wrongly downloaded just the *.c file and not the *.h ones... now it's all OK with a simple 'make'. In fact it was probably a mistake in the CTAN archive (a tarred archive is announced in the readme).
thanks again, gm ---------------------------------- E-Mail: Guido Milanese <[EMAIL PROTECTED]> Vocal Ensemble Ars Antiqua, Genova, Italia Homepage: http://www.arsantiqua.org + + + GAUDETE IN DOMINO SEMPER + + + ----------------------------------
