ABI 5 is for compatibility; narrow-character applications (and termcap) wouldn't benefit as much from ABI 6. =20 > For those interested my current plan with ncurses is the following for fr= eebsd > 13.0: > - split terminfo from ncurses (like the upstream build system) so a futur= change > in high level ABI will impact less consumers offhand, I see that 2/3 to 3/4 of the consumers use termcap or terminfo. My script tells me that - I've not integrated that into something that would relate the results to packages, since I was mainly interested in comparing curses/terminfo/termcap usage on a variety of systems. (I recall there's some problem using it with Solaris - when I revisit that and get "enough" data, I'll probably make a nice table on a webpage). > - only keep the widechar version of ncurses in base > - add the pkgconf file in base to ease the ports tree. >=20 > Again for people who don't want to rebuild everything compat12x package h= as been > created and can be used to have all binaries working. >=20 > Best regards, > Bapt --=20 Thomas E.
