Hi,

it took me the better part of this evening to (re-)find a bug in the Makescript of libtiff-util. I then remembered that I found the same one some time ago, and I am quite sure that I have reported it.

And as your bugzilla is down again, I have no way to check :-)

I use Debian Sarge with xsane as scan utility. Xsane produces TIFF with JPEG encoding.

I wanted to convert these TIFFs to PDF using "tiff2pdf -j ...." but I always got a warning that "libtiff had to be compilied with the jpeg option".

tiff2pdf.c uses some defines (in this case JPEG_SUPPORT) that are set when compiling the libtiff branch, but not during the compilation of the "tools" branch.

As a quick fix I put a !#define JPEG_SUPPORT 1" into tiff2pdf.c and got the functionality I wanted.

Kind regards

Michael
