I use the TIFF library version 'beta035' and I use the IJG-JPEG library. Both works fine, but if I try to read a TIFF image with JPEG compression I get always a error message like "Quantization table 0x0 not found" etc. (my 'tiffconf.h' is OK, with '#define JPEG-SUPPORT' and my 'tiff_jpeg.c' is OK, etc. ...)

Was the original file created by a LIBTIFF program, or did it come from somewhere else? What happens when you run "tiffinfo" or "tiffdump" on it? The Tom Lane/Sam Leffler implementation of Tech Note #2 JPEG-in-TIFF is a good one, but there may be some old bogus TIFF 6.0 stuff floating around (I seem to recall that the Microsoft/Wang "Imaging Solutions" package was generating old files...).
