\`configure' configures this package to adapt to many kinds of systems.
Usage: ./configure [OPTION]...
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`/usr/local/bin', \`/usr/local/lib' etc. You can specify
an installation prefix other than \`/usr/local' using \`--prefix',
for instance \`--prefix=$HOME'.
For better control, use the options below.
--disable-readline Disable line editing support
--without-readline Don't use GNU readline even if it is available
--without-editline Don't use editline even if it is available
--with-readline-includes=DIR Specify where readline include directory is
--with-readline-library=DIR Specify where readline lib directory is
--with-ncurses-library=DIR Specify where ncurses lib directory is
--disable-sechash Disable support for hashes other than MD5
--without-nettle Don't use nettle even if it is available
--without-nss Don't use NSS even if it is available
--without-tomcrypt Don't use libtomcrypt even if it is available
--disable-cmdmon Disable command and monitoring support
--disable-ntp Disable NTP support
--disable-refclock Disable reference clock support
--disable-phc Disable PHC refclock driver
--disable-pps Disable PPS refclock driver
--disable-ipv6 Disable IPv6 support
--disable-rtc Don't include RTC even on Linux
--disable-privdrop Disable support for dropping root privileges
--without-libcap Don't use libcap even if it is available
--enable-scfilter Enable support for system call filtering
--without-seccomp Don't use seccomp even if it is available
--disable-asyncdns Disable asynchronous name resolving
--disable-forcednsretry Don't retry on permanent DNS error
--without-clock-gettime Don't use clock_gettime() even if it is available
--disable-timestamping Disable support for SW/HW timestamping
--enable-ntp-signd Enable support for MS-SNTP authentication in Samba
--with-ntp-era=SECONDS Specify earliest assumed NTP time in seconds
since 1970-01-01 [50*365 days ago]
--with-user=USER Specify default chronyd user [root]
--with-hwclockfile=PATH Specify default path to hwclock(8) adjtime file
--with-pidfile=PATH Specify default pidfile [/var/run/chronyd.pid]
--with-rtcdevice=PATH Specify default path to RTC device [/dev/rtc]
--with-sendmail=PATH Path to sendmail binary [/usr/lib/sendmail]
--enable-debug Enable debugging support
Fine tuning of the installation directories:
--sysconfdir=DIR chrony.conf location [/etc]
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--datarootdir=DIR data root [PREFIX/share]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/chrony]
--localstatedir=DIR modifiable single-machine data [/var]
--chronyrundir=DIR location for chrony sockets [LOCALSTATEDIR/run/chrony]
--chronyvardir=DIR location for chrony data [LOCALSTATEDIR/lib/chrony]
Overriding system detection when cross-compiling:
--host-system=OS Specify system name (uname -s)
--host-release=REL Specify system release (uname -r)
--host-machine=CPU Specify machine (uname -m)
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
CPPFLAGS C preprocessor flags, e.g. -I<include dir> if you have
headers in a nonstandard directory <include dir>
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
Use these variables to override the choices made by \`configure' or to help
it to find libraries and programs with nonstandard names/locations.
