not working.. tmux failed to compile In file included from tmux.h:36:0, from alerts.c:24: compat.h:326:9: error: conflicting types for 'forkpty' pid_t forkpty(int *, char *, struct termios *, struct winsize *); ^ In file included from compat.h:126:0, from tmux.h:36, from alerts.c:24: /usr/include/pty.h:39:12: note: previous declaration of 'forkpty' was here extern int forkpty (int *__amaster, char *__name, ^ make: *** [alerts.o] Error 1

I met this error also (build tmux 3.3a with static link) and have resolved it with adding "--with-termlib" to the configure command line of ncurses. the entire command line is:

cd ${BASEDIR}/ncurses-${NCURSES_VERSION}
./configure --prefix=$TMUXTARGET --with-termlib --with-default-terminfo-dir=/usr/share/terminfo --with-terminfo-dirs="/etc/terminfo:/lib/terminfo:/usr/share/terminfo"
make && make install

from ./configure --help:
--with-termlib generate separate terminfo library

It's a great script~

FYI, here are some updates to support building new version tmux with static link. avoid the error of "conflicting types for 'forkpty'"
to add "--with-termlib" option for ncurses configure command line:

./configure --prefix=$TMUXTARGET --with-termlib --with-default-terminfo-dir=/usr/share/terminfo --with-terminfo-dirs="/etc/terminfo:/lib/terminfo:/usr/share/terminfo"

@blreay thx, I've updated the gist and added the --with-termlib option.
