As of this morning the behavior of pdfroff under Cygwin seems to have
changed for me: the PDF output that it produces is (often) blank:
* It seems to have the right number of pages, but all of the pages are blank.
* I tried several different viewers including Adobe Acrobat, the PDF
displayer in Firefox, and the PDF displayer in VSCode; all show the
same blank output.
* Historically pdfroff has worked consistently for me with no
problems. Files that produce blank output today worked fine in the
past (perhaps a few months ago?).
* The behavior is not totally consistent: some files still work while
others don't. After poking around a bit, I was able to find a
single-line change that flips the behavior between working and not
working. I have attached the file (homa.7), which can be compiled with
"pdfroff -man homa.7 > homa.pdf". In its current form, this file
generates blank output for me. But, if I delete line 561 (".IR
max_incoming /(N+1).") then the file generates viewable output.
* In cases where the output is blank, I tried using "groff -T ascii"
instead, and this produces fine output.
I am also attaching output from "cygcheck -s -v -r > cygcheck.out", in
case that sheds some light.
Any help would be much appreciated; is it possible that I am doing
something wrong?
As pdfroff is a shell script, you can run it with `sh -vx /bin/pdfroff ...` to
see what it is doing;
append ` |& tee pdfroff-blank.log` to capture the output, to get help here about
what it is doing;
ask on the groff list gr...@gnu.org, report a bug to gr...@gnu.org based on:
https://git.savannah.gnu.org/cgit/groff.git/tree/PROBLEMS
and
https://git.savannah.gnu.org/cgit/groff.git/tree/BUG-REPORT
or on the bug tracker:
https://savannah.gnu.org/bugs/?group=groff
As this is Windows, sometimes weird stuff happens, so updating Cygwin packages,
and/or reboot, sometimes fix unexpected weirdness.
