|
|
.Nm
|
|
requires LibreSSL
|
|
.Pq Fl ltls
|
|
and ncurses
|
|
.Pq Fl lncursesw .
|
|
It primarily targets
|
|
.Fx
|
|
and macOS,
|
|
as well as Linux.
|
|
.Bd -literal -offset indent
|
|
\&./configure
|
|
make all
|
|
sudo make install PREFIX=/usr/local
|
|
.Ed
|
|
.
|
|
.Pp
|
|
If your system installs LibreSSL
|
|
in a non-standard path, set
|
|
.Ev PKG_CONFIG_PATH
|
|
for
|
|
.Nm ./configure .
|
|
For example,
|
|
.Bd -literal -offset indent
|
|
PKG_CONFIG_PATH=/opt/libressl/lib/pkgconfig ./configure
|
|
.Ed
|
|
.
|
|
.Pp
|
|
If your system is incapable of providing LibreSSL,
|
|
consider building it manually and installing to
|
|
.Pa /usr/local ,
|
|
adding
|
|
.Pa /usr/local/lib
|
|
to
|
|
.Pa /etc/ld.so.conf
|
|
and running
|
|
.Xr ldconfig 8
|
|
if needed.
|
|
It may also be necessary to create
|
|
.Pa /etc/ssl/cert.pem
|
|
as a symbolic link to
|
|
.Pa /etc/ssl/certs/ca-certificates.crt
|
|
or similar path.
|
|
.
|
|
.Pp
|
|
The
|
|
.Nm sandman
|
|
wrapper is provided for macOS
|
|
to stop and start
|
|
.Nm
|
|
on system sleep and wake.
|
|
Install it as follows:
|
|
.Bd -literal -offset indent
|
|
make scripts/sandman
|
|
sudo make install-sandman
