Description John Reiser 2005-07-11 14:59:22 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
ps2pdf fails to convert this simple input which produces one page with 4 copies of the C,D scales of a sliderule.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. ps2pdf --verbose >/tmp/foo.pdf

Actual Results:  $ ps2pdf --verbose >/tmp/foo.pdf
GNU Ghostscript 7.07: Unrecoverable error, exit code 1

Expected Results:  Generate /tmp/foo.pdf

Additional info:

A careful reading of "man ps2pdf" suggests that the commandline syntax should be
"ps2pdf - >/tmp/foo.pdf".  If so, then the actual behavior "Unrecoverable error" is a gross usability bug because the message is not related to the error, and gives the user no clue as to what to change in order to obtain the obviously-desired functionality.  A message such as "ps2pdf requires exactly two [non-optional] commandline arguments" is required.

Comment 2 Tim Waugh 2005-07-11 15:15:36 UTC
There is no such option '--verbose'.

Comment 3 John Reiser 2005-07-11 15:51:35 UTC
Yes there is such an option '--verbose'.  This transcript shows that --verbose
exists, and its use alters the behavior of ps2pdf, mostly in an expected way. 
--verbose gives a diagnostic message on stderr instead of just an exit status
code.  --verbose also changes the exit code from fail [1] to success [0], while
the usually-expected behavior would be to leave the exit code the same.
$ ps2pdf >/tmp/foo.pdf
$ echo $?
1  ## ps2pdf failed
$ ps2pdf --verbose >/tmp/foo.pdf
GNU Ghostscript 7.07: Unrecoverable error, exit code 1
$ echo $?
0  ## ps2pdf "succeeded"
$ ls -l /tmp/foo.pdf

Comment 4 Tim Waugh 2005-07-11 16:00:40 UTC
No, there is no such option as '--verbose'.  You are using ps2pdf incorrectly.
