GROFF VERSION:
1.20. But the bug still exist in 1.21 (I checked the source).
MACHINE:
Generic x86-64 machine.
OS:
Linux 2.6.35.7 (distribution Fatdog64)
COMPILER:
gcc 4.4.3
INPUT FILES:
none - this is behavioural problem
COMMAND LINE:
groffer man:djvu
groffer --tty man:djvu
(Note: djvu can be replaced with any man page)
DESCRIPTION OF INCORRECT BEHAVIOUR:
The first invocation (without --tty) just hangs on the terminal.
The second invocation (with --tty) produces an error of not being able to
find
pager, when pager program (less) is obviously available.
main_display(): no pager program found for tty mode; at /usr/bin/groffer
line 1943.
cannot remove path when cwd is /tmp/groffer_1684_xarx for
/tmp/groffer_1684_xarx: at /usr/lib64/perl5/5.10.1/File/Temp.pm line 902
SUGGESTED FIX [optional]:
Patches attached for contrib/groffer.pl and contrib/man.pl
