ImageMagick 6.7.4 convert

[mbohnert@fuse.net]

I compiled ImageMagick version 6.7.4 on AIX 6.1. It appeared to compile and install fine. I have a 5MB TIFF containing 4 pages. The first page is type 4 and the next 3 pages are type 7 (JPEG). I'm trying to run convert to convert it to pdf. The type 7 pages convert but the 1st page is blank.

convert spits out the following error:

lt-convert: UnableToOpenFile `': A file or directory in the path name does not exist. @ error/tiff.c/WriteGROUP4Image/2047

convert does create a 24MB pdf file as a result and I can see the last 3 pages but the 1st is blank.

Is this a bug in this version of ImageMagick perhaps.

BTW, I'm a UNIX person but new to tiff, jpeg, pdf conversions.

Thanks for your help.

I am not sure I can help much other than to suggest you check your version of libtiff and upgrade if necessary to a current version. If you do that, you need to recompile IM again from source, if that is how you installed it.

Thanks. I've recompiled several times.
I'm using libtiff-4.0.0 and libjpeg-8c

I tried tiff2pdf and in that case I can see page 1 (which is type 4) but not the other 3 pages (which are type 7)

Output from configure says JPEG support is enabled
