【问题描述】：
我正在尝试为嵌入式 linux 系统构建 chorny。我目前能够编译、运行和同步时间。我还可以使用 MD5 启用身份验证，并且效果也很好。
我不知道如何启用 SHA 哈希。在构建包时使用它，但配置中没有选项。以前有人做过吗？
谢谢
这是我将 chrony.keys 文件中的哈希类型设置为 SHA1 时的输出：
root@gsdm:~# chronyd -d
2000-01-08T00:54:56Z chronyd version 2.2 starting (+CMDMON +NTP +REFCLOCK +RTC -PRIVDROP -SCFILTER -SECHASH +ASYNCDNS +IPV6 -DEBUG)
2000-01-08T00:54:56Z Unknown hash function in key 12
2000-01-08T00:54:56Z Initial frequency 1.355 ppm
当我运行 ./configure -h 我得到这个：
`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/user'.
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
--readline-dir=DIR Specify parent of readline include and lib directories
--readline-inc-dir=DIR Specify where readline include directory is
--readline-lib-dir=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-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
--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-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]
--infodir=DIR info documentation [DATAROOTDIR/info]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/chrony]
--localstatedir=DIR modifiable single-machine data [/var]
--chronysockdir=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.
