Archived - Beta test MLAT software for Raspberry Pi

[Swen]

Hello together,

since 3 days i have two receivers and they are only offline... I get something like this:



Flightdata will come from dump1090-fa and this is working.

No aircrafts are tracked.

Netcat on port 30002 give me raw data:

I'm using Stretch as Raspi-OS fully upgraded to the last files.

The new version of fr24feed (1.0.19-2) fails to start on my system (pi64 including armhf libs):

How do I fix this (or revert to the previous version)?

As you can see by the numerous new threads people are creating, there are mixed results with the update depending on the update method. Dump1090-MR has been revoked and your config needs to be reconfigured for -mutability

However being 64b may have an impact.. Seems to be some pretty big shifts causing headaches *sigh*

[helios]

Yes, my issue isn't related to dump1090.
The previous version was running fine on 64 bit with the armhf libs.
strace:

--- SIGILL {si_signo=SIGILL, si_code=ILL_ILLOPC, si_addr=0x6d500} ---
+++ killed by SIGILL +++
Illegal instruction

Only thing I can suggest is to pull the prev version back from the repo (as long as it remains for the time being) and disable the auto update.

Util we hear word from the devs on what was changed on this version and how it's expected to work it's a case of putting out fires with blacked out sunglasses on.

[Oblivian]

Assuming you have the other dependency that appears newly needed.. librtlsdr0

[helios]

fr24feed seems to be statically linked.

$ ldd /usr/bin/fr24feed
not a dynamic executable

Apart from a dynamically linked binary the source code would be appreciated. (Or/And a changelog).


If someone runs in the same problem, the old binary can be found here:

http://repo.feed.flightradar24.com/rpi_binaries/fr24feed_1.0.18-9_armhf.deb

Sorry about the issues with the new version. We have rolled back to the previous version so any new downloads through the script should get v.18-9 automatically but might not work for those already on v.19-2. Currently looking into why the issues are occurring and will have them fixed asap.

Will get back with an Update as soon as possible.

Can anyone with v19-2 check if their logs are being written to /var/log/syslog and if it shows any errors there?

Thank you!

Anyone that is affected by the current 19-2 version, please leave the feed as is if you want and we will release a new version with a fix. Upon which if you haven't turned off autoupdate, it will be downloaded and everything will start working again.

[visualVHHH]

I am affected by the 19-2 version. I cannot feed any data to FR24 now.

How can I know I have auto update turned on in my raspberry pi?? So sorry that I have little knowledge with this gadget.

It still works. Just rerun the signup wizard and ensure the included dump1090 is configured/working. See dump1090 missing from debian thread...

I do not know whether this is related to the updates mentioned... but I was running Raspian Jessie for 6 months with the DVB-T tuner... and after 6 months ( I turn off the system every night), now when I turn on power, it is not sharing any data... the only workaround I found was to install a fresh fr24feed app every time I power up the system. Any help ? 10x
