hi I've install your package on my ds216play (Monaco).
I run it but I fail to see any airplay source on my iphone.
I checked the log and here was what I got:

*** Error in `/var/packages/AirConnect/target/airupnp': free(): invalid pointer: 0x7101fb60 ***

it seems some error occurred but I can't find any solution related to it.
Could you plz tell me what was wrong or any clue on solving it ?

[philippe44]

Can you try to run it first on a classical computer like a PC Linux, Windows or a Pi? I want to know if the issue is related to the DS216 or the name of your players (unicode problem)

[looching]

i've tried running the windows system version，it worked but those names were not displaying properly. So I think it is not a unicode problem. let me try to reinstall on ds216 or find a Pi to rerun it.

[looching]

tried to clone the repo and rerun it on ds216, got same result

I ran it on a Pi and got the same result:

it seems the arm version is not working on my machine

[philippe44]

If you also have a problem on the Pi, it's likely a multichar player name problem. Can you give it a different name? Other than that, do you know how to run it under gdb? If you do, I'll build a version with symbols here https://www.dropbox.com/s/flyr88njifyiso1/airupnp-arm?dl=0

[looching]

Thank you and no, I can't change all the names. I'll try your new version and see how to get you some hints with gdb

[looching]

I just ran you new version and it works on my Pi. I didn't try gdb. Do you still need it ?

[philippe44]

This is strange because the modifications I've made only affect the application when actually streaming, or when exiting. I don't understand why it has any impact in your case. Don't need the gdb then, but can you post a log?

[looching]

Sorry I somehow broke my Pi and can't get log out of it. I'll post log here later when I fix it.

[philippe44]

I'll close the issue - feel free to re-open if needed

[huzheyi]

I've got a same problem as this topic.
I ran airconnect perfectly on my windows PC, while it threw an error on my amlogic device running Volumio.
The dropbox link you provided before is now out of date, could you please upload a new one ?
