    Linux NDI & CentOS

    Hi,

    First up, out of interest, which Linux dist is recommended/ most stable for NDI development?

    Now my main problem, has anyone run into issues with the avahi/dbus sub sytem on CentOS 7 64? I am getting Seg faults in dbus.

    Code:
    Program received signal SIGSEGV, Segmentation fault.
    [Switching to Thread 0x7fffe4ff9700 (LWP 7871)]
    0x00007ffff679d10c in _dbus_list_unlink (list=list@entry=0x8e06c0, link=link@entry=0x7ffff0001750) at dbus-list.c:498
    498           link->prev->next = link->next;
    Generally only occurs after creating a receiver on a stream originating on a Win7 machine.

    I have installed an Ubuntu Server 16.10 instance and the code seems to be stable on it hence wondering if its a CentOS specific issue?

    Thanks, Blake

    I had similar issues with crashes in avahi/dbus on Ubuntu 14.04. On Ubuntu 16.04 I had no such problems.

    Thanks for the feedback. I am experiencing similar on Ubuntu 16.10 and Debian (Jessie) as well. Mostly random from what I can see. I also find that it's more stable when running code through GDB however then it's also running ALOT slower. Makes debugging extremely difficult.

    I'm open to any suggestions for alternate ways to better debug this.

    if you are crashing in Avahi under Linux, see if its associated with discovery of 2 NDI sources with the same name. If so that's a known old bug, and a newer NDI Library build may fix it.

    We are using Ubuntu 16.10 and 16.04 and they are working well.

    Out of interest, which NDI linux library build are you using with CentOS 7 ?
