Another build error on Ubuntu 22.04

elfzweik commented 1 year ago

I was hit by a build error similar to #464. I'm also with Ubuntu 22.04 and gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0. So I assume Iit was caused by the new version of GCC. The error is:

The problem I met is at src/wifi instead of src/dhcp. I tried to patch it by trying the way of #464 and #458. But as a newbie, it is proved beyond my ability after several hours googling stackoverflow and askubuntu。 Could anyone show me a workaround? Thanks a lot!

Well, trying to use cmake to compile. And with a several warnings, the compilation finished. And miracle-wifid service is running. But I tried connect as peer, the error is:

elf@elf-ubuntu:~$ sudo miracle-wifictl
[ADD] Link: 2
[wifictl] # select 2
link 2 selected
[wifictl] # list
  LINK INTERFACE                FRIENDLY-NAME                  MANAGED   
     2 wlp60s0                  elf-ubuntu                     yes       

  LINK PEER-ID                  FRIENDLY-NAME                  CONNECTED 

 0 peers and 1 links listed.
[wifictl] # p2p-scan
ERROR: cannot change p2p-scanning state on link 2 to 1: Invalid argument (ctl_link_set_p2p_scanning() in /home/elf/Downloads/miraclecast/src/ctl/ctl-wifi.c:739)

And when searching solution to this error, I found that @albfan mentioned acting as peer is WIP. So I tried act as source.

elf@elf-ubuntu:~$ sudo systemctl stop NetworkManager.service
elf@elf-ubuntu:~$ sudo systemctl stop wpa_supplicant.service
elf@elf-ubuntu:~$ sudo miracle-sinkctl
[ADD] Link: 2
[sinkctl] # run 2
ERROR: cannot change p2p-scanning state on link 2 to 1: Invalid argument (ctl_link_set_p2p_scanning() in /home/elf/Downloads/miraclecast/src/ctl/ctl-wifi.c:739)
now running on link 2

And my another PC running Windows 10 cannot find the wireless display. I have no idea what is the cause.

By the way, when my laptop acts as peer, can I use WIFI? When windows connect miracast the wifi is still available. If the wifi is not available when running miraclecast, it is not so useful.

Hi, then this issue should be closed. Any question about #4 should be in that issue or new issue that matches issue subject

albfan / miraclecast
