Unknown TERM: /usr/share/terminfo/x/xterm

[scherrey]

x4 doesn't understand my terminals. I get the following messages:

kde konsole:
scherrey@satriani:~/projects/forth/x4$ ./x4
Unknown TERM: /usr/share/terminfo/x/xterm

Au Revoir!

rxvt:
scherrey@satriani:~/projects/forth/x4$ ./x4
Unknown TERM: /usr/share/terminfo/r/rxvt

Au Revoir!

This is running on a Kubuntu 14.04 host:
scherrey@satriani:~/projects/forth/x4$ uname -a

you are using a debian based distro it seems
#3
you do not have /usr/share/terminfo/anything
$ dir /usr/share/terminfo/
1/ 2/ 3/ 4/ 5/ 6/ 7/ 8/ 9/ a/ A/ b/ c/ d/ e/ E/ f/ g/ h/ i/ j/ k/ l/ L/ m/ M/ n/ N/ o/ p/ P/ q/ Q/ r/ s/ t/ u/ v/ w/ x/ X/ z/
debian based distros STUPIDLY put terminfo in /var/lib/terminfo
and i never added the code to look there
it annoys me lol
one quick fix would be to cp -r /lib/terminfo /usr/share
ive done that before
haha what distro do you use?
technically i should look in /etc/terminfo and in the utterly MORONIC /lib/terminfo and also in ~/terminfo
gentoo
occasionally i use mint
oh wow haven't used that in ages. I tried funtoo for a few years but, as a developer, it's so hard to keep the system consistent.
another fix you could do is edit src/ext/terminal/term.f and edit the path specified in there to where your terminfo files are
cool I'll give it a try some time.
personally i think debian based distros putting terminfo in /lib is DUMB
i always copy them into their correct location as defined by the FSHS

I'm getting this too, and I'm using a distribution (Void Linux) with a fully populated /usr/share/terminfo.

But I'm only getting it happen when I start x4 under tmux. Under dvtm or mtm it's fine; I haven't tried screen.

I'm using the x86_64-musl variant of void, if that makes a difference. The message I get is

Unknown TERM: /usr/share/terminfo/3/3.3a

which is strange, because my TERM is set to 'tmux-256color' (although the same message pops up whatever I set it to).

[thamesynne]

Ah.. it turns out that tmux is setting TERM_PROGRAM_VERSION to 3.3a. If I unset this, x4 starts up just fine. Which implies that envcmp is only comparing the prefix of a name, not ensuring that they're both the same length. I fixed it by changing envcmp to

: envcmp        ( a1 a2 --- a2 n1 t | f )
  2dup swap count comp 0=
  if
    swap c@ + dup c@ '=' = if
      1+ strlen true
    else
      drop false
    then
  else
    2drop false
  then ;

but I'm certain there's a more elegant way to do that and avoid nested conditionals.

I need to fix that bug, i discovered my environment compares were matching xyzzy if i searched for xyz which is wrong :)
Ill try get a push in on that asap
