I'm trying to enable 24bit support on the terminal (via SSH) on my FreeBSD 12 installation without success.

I tried to create a terminfo file with the contents:

xterm-24bit|xterm with 24-bit direct color mode,
 use=xterm-256color,
 sitm=E[3m,
 ritm=E[23m,
 setb24=E[48;2;%p1%65536%/%d;%p1%256%/%255%&%d;%p1%255%&%dm,
 setf24=E[38;2;%p1%65536%/%d;%p1%256%/%255%&%d;%p1%255%&%dm,

And then executed the command (after installing ncurses):

$ tic -x -o ~/.terminfo xterm-24bit.terminfo

But when trying to run emacs, I get:

emacs: Cannot open terminfo database file

So, I tried to use infocmp -Cr to generate a termcap version and updated the db running:

# cap_mkdb /usr/share/misc/termcap

That almost worked, the emacs opens but black and white only :(

My terminal does support 24bit color and I use this mode via ssh on my other Linux machines.
Does anybody uses 24 bit terminals on FreeBSD?

ssh terminal freebsd emacs terminfo

  I do. I use the one that I wrote. (-: That really should not be the question here. You actually have three questions that this should ask: what needs to be done in the terminal database, what terminal database it in fact needs to be done in, and how to get emacs to recognize that.

  It would only work if emacs is linked to an ncurses library using terminfo. But the FreeBSD emacs package links to the system ncurses, which is configured to use only termcap. You could configure/compile emacs yourself, but this group is of little use for advice on that sort of thing.

  @ThomasDickey, I have compiled mine, but didn't know about linking to another ncurses library. I'll do some research about it. Thanks!

  You might be able to use the ncurses port; I checked the system library by strings, looking for terminfo.
