mkdir build
cd build/
../autogen.sh g --prefix=/usr

1.3 故障排查¶

如果无法连接到 miraclecast，运行

sudo miracle-wifid --log-level trace

查看调试信息。如果错误描述为

1	`ERROR: supplicant: HUP on dhcp-comm socket on p2p-wlo1-1 (supplicant_group_comm_fn() in ../../../src/wifi/wifid-supplicant.c:247)`

尝试

sudo miracle-dhcp --netdev <your_interface>

在我的案例中，该命令报错：

1	`ERROR: dhcp: execution of ip-binary (/bin/ip) not allowed: No such file or directory (parse_argv() in ../../../src/dhcp/dhcp.c:877)`

运行

1	`which ip`

输出

1	`/usr/sbin/ip`

因此解决方案为

sudo ln -s /usr/sbin/ip /bin/ip

Troubleshooting¶

If you cannot connect to miraclecast, run

sudo miracle-wifid --log-level trace

to show debug information. And if the error is described as

1	`ERROR: supplicant: HUP on DHCP-comm socket on p2p-wlo1-1 (supplicant_group_comm_fn() in ../../../src/wifi/wifid-supplicant.c:247)`

try

sudo miracle-DHCP --netdev <your_interface>

In my case, the command failed with error:

1	`ERROR: DHCP: execution of ip-binary (/bin/ip) not allowed: No such file or directory (parse_argv() in ../../../src/dhcp/dhcp.c:877)`

I ran

1	`which ip`

it prints

1	`/usr/sbin/ip`

So the solution was

sudo ln -s /usr/sbin/ip /bin/ip

```
