My plan was simply to build a list of pages that belong to one document and then:

$tiffcp page1.tif page2.tif... pageN.tif doc.tif $tiff2pdf -o doc.pdf doc.tif

If any of the TIFFs is an OJPEG TIFF, the first command fails with a long message including:

You forgot to tell us what version of libtiff you are using. Of course it does make a difference.

Indeed. Sorry about that. I am using the latest stable version 3.9.4 compiled against jpeg-8b with MinGW/MSYS on Windows Vista.

The JPEG in question is displayed as a blob by Windows Image Preview but I can view it with XnView (www.xnview.com).
