Will not compile on gentoo.

[drforbin]

Since ncurses was split into tinfo symbols are missing.

I had to add tinfo lib to get it to compile.
Do you want me to create a commit and pull request?

here is diff.

It fails during linking.

@drforbin I will try to setup a local gentoo system on which to test.

[drforbin]

thank you sir...As I said my patch works

[jaltman]

The problem with a patch which always attempts to link against the tinfo library is that it won't work on Linux distributions which do not have a tinfo library to link against; for example Debian. The logic I provided in the prior patch was overly complicated.

This works for me on Gentoo 6.12.58 gcc (Gentoo 15.2.1_p20251122 p3) and on Debian Trixie.
