[Message part 1 (text/plain, inline)]

As far as I can see, the current version of dvtm does not work properly
with programs such as htop etc.

To reproduce:
```
$ guix package -i dvtm
$ dvtm
$ htop
```
It only worked properly once I added something like:
`export TERMINFO_DIRS="/home/jelle/.guix-profile/share/terminfo"`.

Would a proper fix be to simply add a native-search-path declaration to the
dvtm package? If so, I can prepare a patch this weekend.

Thanks,
Jelle

‘TERMINFO_DIRS’ is a search path of ncurses.  However, because search
paths of dependencies are not honored, it doesn’t get set:

  https://bugs.gnu.org/22138

This is what we should fix.

It would feel wrong to add ‘TERMINFO_DIRS’ as a search path of dvtm and
everything that depends on ncurses.

Thanks,

Fixing this properly seems like it would take effort indeed.

Am I correct in assuming that as a temporary (personal) workaround, I can
just
install ncurses in my profile as well?

Perhaps guix can warn if you install a package which has a dependency
with a search path like ncurses? Or would this be too much of a hassle
to implement?

It would not solve the issue, but at least prevent people from
not understanding why their packages are not working. WDYT?

Good question, not sure it would be significantly easier than fixing the
core issue.  Dunno!
