在 linux 上编译 isc-dhcp-server

Question

我想从这个存储库的源代码编译和调试 DHCP 服务器： https://github.com/isc-projects/dhcp

我所做的一切：

./configure

make

但是这两条命令我有很多错误。

/usr/bin/ld: dhcpd-mdb.o:/home/ali/programming/c/opensource/dhcp/server/mdb.c:70: multiple definition of `dhcp_type_host'; dhcpd-omapi.o:/home/ali/programming/c/opensource/dhcp/server/omapi.c:50: first defined here
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:529: dhcpd] Error 1
make[2]: Leaving directory '/home/ali/programming/c/opensource/dhcp/server'
make[1]: *** [Makefile:970: all-recursive] Error 1
make[1]: Leaving directory '/home/ali/programming/c/opensource/dhcp/server'
make: *** [Makefile:496: all-recursive] Error 1

但是为什么？如何编译 isc-dhcp-server ？

我的 linux 发行版是 debian v11。

更新：

在编译 isc-dhcp 之前，我安装了它的要求。

# apt install bind9-dev

然后我运行这个命令而不是 make ：

make -C server install

但是会出现这个错误：

make: Entering directory '/home/ali/programming/c/opensource/dhcp/server'
Making install in .
make[1]: Entering directory '/home/ali/programming/c/opensource/dhcp/server'

这是我的配置输出结果：

     ISC DHCP source configure results:
    -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Package:
  Name:          DHCP
  Version:       4.4.2b1

C Compiler:      gcc

Flags:
  DEFS:          -DHAVE_CONFIG_H
  CFLAGS:        -g -O2  -Wall -Werror -fno-strict-aliasing -I$(top_srcdir)/includes -I/home/ali/programming/c/opensource/dhcp/bind/include

DHCP versions:   DHCPv4 and DHCPv6

Features:
  debug:         no
  failover:      yes
  execute:       yes
  binary-leases: no
  dhcpv6:        yes
  delayed-ack:   yes
  dhcpv4o6:      no
  relay-port:    no

Developer:
  ATF unittests : no


Now you can type make to build ISC DHCP

解决方案

我们应该从here克隆isc-dhcp服务

您似乎正在编译来自旧仓库的最后一次提交。 github 页面指向更新的 repo，地址为 isc's gitlab site 的更新提交。

您也可以切换到最新的稳定标签git checkout v4_4_2_p1以获得更好的稳定性。

注意，我能够使用 gcc-9 构建它，对我来说，最新的稳定标签不会使用 gcc-10 构建，它是 debian 11 的软件包版本。这是open issue
