Install issue

[sub]

It's still fairly early days for me understanding the best way to approach these sorts of issues when users have them on Linux.

A couple of options:
1) you temporarily allow me to remote in to this Linux box via ssh, adding port 22 port forwarding in your router to whatever the Linux machine is, with this I can run the debug session from here, and watch where it crashes. I'd only need access for 20 minutes or so.
2) or you try running:

Code:

gdb ./DeviceHostLinux -device:adapter0 -type:ATSC -parent:0 -scan:/usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB
run

and when it segfaults try typing 'backtrace'.

The first of those would be the most straight forward. For the second, it might give us a bit more to go on, but we may have to repeat the process with a debug build to get better info.

Well this what got back
gdb: unrecognized option '-device:adapter0'
Use `gdb --help' for a complete list of options.

Sorry, try:

gdb --args ./DeviceHostLinux -scan:/usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB

run

backtrace

Can you try replacing your DeviceHostLinux with this newer version, and run:

./DeviceHostLinux -verbose -device:adapter0 -type:ATSC -parent:0 -scan:/usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB

This version should generate more logging. Hopefully something useful.

come before as so run gdb

Running outside of gdb, did it produce more logging?

Nope just some old message as before

I tested reg Ubuntu 19.04 it was the same as PoP_OS any way the Command ./DeviceHostLinux -device:adapter0 -type:ATSC -parent:0 -scan:/usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB seem be working under 18.0.4.2 just fine so what ever the problem is with 19.04 as both PoP_OS and Ubuntu are doing it which a real drag as is less bugg at leases for me.

Ok good to know. I'll try PoP_OS when I get a chance.

I was thinking about it last night, and I suspect it'll come down to the version of libdvbv5. It possible this distribution is using an older version.
