Running old version of miraclecast on Ubuntu 17.10

[ghost]

The output of systemctl --version is

I am using ubuntu 17.10 and the output of /res/test-hardware-capabilities is wlp1s0 supports P2P and I know this computer can use miracast on windows, and miracast compiled and installed without errors and I already tried to reboot (I also followed the steps on https://github.com/albfan/miraclecast for how to use)

Seems you do not install dbus miraclecast policy. Read FAQ https://github.com/albfan/miraclecast/wiki/FAQ#install-dbus-policy

Remember to close if that works

[albfan]

That line do not match

https://github.com/albfan/miraclecast/blob/master/src/wifi/wifid-supplicant.c#L2481

Did you modify the code? That line says that miraclecast find /usr/bin/wpa_supplicant and then that file do not exists (has no sense)

supplicant_find search for wpa_supplicant in your PATH. There was as --wpa-bindir option to set the path for wpa_supplicant. These days if you don't have wpa_supplicant in your PATH, just launch the wifi daemon with

$ PATH=$PATH:/path/for/your/wpa_supplicant miracle-wifid --any-option-you-want

See /path/for/your/wpa_supplicant is the path to the parent dir of wpa_supplicant (like /usr/local/bin for /usr/local/bin/wpa_supplicant)

[albfan]

supplicant_find is a C function, not a command

If you didn't modify the code, then you're using an old version of miraclecast where it looks for wpa_supplicant in /usr/bin/wpa_supplicant, and you have the --wpa-bindir option to set a different path for it.

First locate wpa_supplicant

$ which wpa_supplicant

If that command don't show you any match you need to install it before (or compile yourself, is a similar process than compile and install miraclecast)

Then you can:

• Update your miraclecast code
• use the config option

[ghost]

Ok so i found my wpa_supplicant in /sbin/wpa_supplicant, how can i use it as config option, on which file (./configure, ./autogen, miracle-wifid or miracle-sinkctl and is it just filename --bindir /sbin/wpa_supplicant or something else?)

[albfan]

$ sudo miracle-wifid --wpa-bindir /sbin

Should be enough

I recommend to upgrade your repo anyway

[ghost]

I downloaded it directly from https://github.com/albfan/miraclecast/ but anyway, when I launch it and configure everything, how do i duplicate my screen on my Intel WiDi Smart TV? What is sink and what is peer, what do i need to share to my TV?

Also now when I launch sudo miracle-wifid --wpa-bindir /sbin it hangs anc CTRL + C tells me: ^CNOTICE: caught signal 2, exiting..
ERROR: dbus: syscall failed (-107): Transport endpoint is not connected (link_dbus_removed() in wifid-dbus.c:766)

[albfan]

There's no /use/bin search since August 2016

4601514#diff-744bdd52c5f3b71aac2263033f8c9261L43

Use miraclecast as source is a WIP. You can try it with #172

miracle-wifid is a daemon, so surely it steals terminal input and output, if you want to know what's happening add --log-level (info|debug|trace) to command. That message tells you that miraclecast stop by brute force and something fails.

You can append & to send to background but is better to use various terminals. Run miraclecast as a service is an open issue too, See #98. That way miraclecast could stop gracefully

[ghost]

I am using the newest version of miraclecast

[albfan]

Try to get progress in every comment, your last one left us in same position:

• You 're using the newest version of miraclecast now and everything works so you can close this issue?
• You think you're using the newest version of miraclecast from the very beginning of this issue? Is easy to detect, copy/paste here the line src/wifi/wifid-supplicant.c:2418 and compare with https://github.com/albfan/miraclecast/blob/master/src/wifi/wifid-supplicant.c#L2418. if they are not the same you're not in the lastest version. See lastest version should not accept --wpa-bindir option too

As said, you need a different branch to use miraclecast as source, and some skills to adjust it as it is a WIP. I'm working on it these days, I think is better for you to wait till that is finished (subscribe to #4 issue)

I'm ok with teach you every detail you need to know to get this working, but: are you taking this project as user or as developer?

[ghost]

It still does not work because: sudo miracle-wifid --wpa-bindir /sbin it hangs anc CTRL + C tells me: ^CNOTICE: caught signal 2, exiting..
ERROR: dbus: syscall failed (-107): Transport endpoint is not connected (link_dbus_removed() in wifid-dbus.c:766)

I am using it as a user and would like it if it works.

[albfan]

Read the previous message. It do not hangs, it is a daemon. It is communicating with other miraclecast programs through wpa_supplicant and dbus.

All is explained on README.md

Anyway what you're looking for (use miraclecast as source) is not available yet.

Maybe you want to try other miracast implementations, like https://github.com/intel/wds. I think this project is not mature for your needs (as user). If so please close this issue

[albfan]

Yes. you can run daemon in background (appending & in the end of miracle-wifid command)

[ghost]

Now when i run: miracle-wifid --wpa-bindir /sbin and miracle-sinkctl it does not detect the ADD: 3 or any ADD, when i try run 3 it fails. miracle-wifictl can not do p2p-scan or any command successfully.... how can I fix this I really want to use this program because I want to be able to stream to my TV just like with miracast!

[albfan]

Please reread messages. If I change the subject is because that fit better. This is not a forum but an issue about running miraclecast.

This is the third time I answer that use miraclecast as source (the device here it runs is the stream origin) is a WIP, and you need to try #172

I will close this. Refer to that PR if you want to try it

[shamim2018]

Please tell me an easy way to install and use Miraclecast on Linux Mint 19. I am just an ordinary user, trying to cast my PC on a Sony Smart TV

@shamim2018 open your own issue please
