dhclient-arm交叉编译的问题

我正在尝试使用WiFi加密狗从Dart卡（类似于带有iMX6 CPU的覆盆子Pi）连接到无线网络

我遵循公认的答案。 当我尝试时：

wpa\u请求者-B-i wlan0-c spark\u wifi.conf-D nl80211和&dhclient wlan0

我得到：

sh:dhclient:未找到命令

所以我为ARM寻找dhclient，我找到了最好的 我按照说明做了，但不管我怎么努力，我都无法编译它

我使用的是

yocto

交叉编译器，其中包括以下环境变量：

我在跑步：

/configure--host=arm poky linux gnueabi--cache file=config.cache

结果总结如下：

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

Package:
  Name:          DHCP
  Version:       4.2.5-P1

C Compiler:      arm-poky-linux-gnueabi-gcc  -march=armv7-a -marm  -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9 --sysroot=/opt/poky/1.8/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi

Flags:
  DEFS:          -DHAVE_CONFIG_H
  CFLAGS:         -O2 -pipe -g -feliminate-unused-debug-types  -I${top_srcdir}/bind/include

Features:
  debug:         no
  failover:      
  execute:       

Developer:
  ATF unittests : no


Now you can type make to build ISC DHCP

下一步要做的是

make

，它最终会出现错误：

Making all in bind
make[1]: Entering directory `/home/user/workbench/dhcp/src/bind'
Configuring BIND Export libraries for DHCP.
configure: error: in `/home/user/workbench/dhcp/src/bind/bind-9.8.4-P2':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details
make[1]: *** [all] Error 1
make[1]: Leaving directory `/home/user/workbench/dhcp/src/bind'
make: *** [all-recursive] Error 1

我试着调试它，发现

configure

文件包含以下检查：

# There might be people who depend on the old broken behavior: `$host'
# used to hold the argument of --host etc.
# FIXME: To remove some day.
build=$build_alias
host=$host_alias
target=$target_alias

# FIXME: To remove some day.
if test "x$host_alias" != x; then
  if test "x$build_alias" = x; then
    cross_compiling=maybe
    echo "$as_me: WARNING: If you wanted to set the --build type, don't use --host.
    If a cross compiler is detected then cross compile mode will be used." >&2
  elif test "x$build_alias" != "x$host_alias"; then
    cross_compiling=yes
  fi
fi

echo$cross\u编译

在本部分给出

可能

之后。 我没有正确设置

$host\u alias

和

$build\u alias

，以使这项功能正常工作。 将

cross\u compiling=maybe

更改为

cross\u compiling=yes

也不起作用

感觉就像我在给牦牛刮胡子。。。 我只想连接到WiFi:）

如果有一个地方，我可以下载编译到ARM的dhclient二进制文件，那就太好了
