‘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.

Fixing this properly seems like it would take effort indeed.

 

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

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?

Thanks,
Ludo’.
