This hd530c OpenPLi/enigma based setop box has a triple DVB-C tuner (FBC) with for me a still unknown Tuner brand(Broadcom?).
The Mut@nt hd530c currently runs Tvheadend 79ea2a42c477e315ffa2143252273fe2db0c2165 with 3 frontends detected on a single adapter but using its dvb-c adapters directly within Tvheadend causes Tvheadend to crash as soon as a 2nd channel on a different transponder is tuned on a 2nd/3rd tuner. This happens with enigma enabled in background and with runlevel init 4. There has been some Tvheadend optimizations lately(see issues) to improve multiple frontend behaviour on dual tuners but for this FBC dvb-c tuner it did not improve yet. The good news is that scanning for channels works even on 2 tuners also EPG update.

That's not the problem but why do you compile tvheadend and don't use tvheadend on enigma as @Peter Bašista did "https://octagon-forum.eu/threads/running-tvheadend-directly-on-sf4008.2236/"?
By the way i am using that same mutant as minisatip server with asix network and pulling streams by http (because of the problem reported on #5428 with wan use!)

@Ricardo Rocha, thanks for pointing out the "chroot" option. But I'm still missing a complete step by step howto, google cache didn't reveal that much info on @Peter Bašista his post and I don't feel like registering on that forum.
Would you like to consider writing a step by step tutorial for chrooting debian on the hd530c at this tvheadend forum?
If you have any hints for building/installing dbg versions on openpli/enigma or other methods to produce usefull debug info with the standard tvheadend package I'm willing to try time

@Walter av i didn't tried it for my self but it seens after read it a really better way to run it compared with all the workarounds needed to compile it to enigma!
Let's try to bring @Peter Bašista to discussion... i am sure he don't have troubles in explain the process!
Regarding the usage of Debootstrap to bootstrap a Debian base system in a directory and then use it with chroot on your receiver, there are no special requirements that I am aware of. Just follow the guide, mount the directories properly and it should work fine. This part of /etc/fstab may be useful:
I am not using this approach anymore, because for a simple use case like just using Tvheadend and nothing more, it is simpler for me to build it using bitbake. I have posted another answer to Stack Exchange question about how to install Tvheadend on a set-top-box running OpenEmbedded-based Linux, which roughly explains one of the ways to do it.

When you build it using bitbake, it will generate all the dbg packages as well. If some dependencies of dbg packages are missing, you can simply build them in the same way.
Recompiled Tvheadend 4.3x 7fdc6f0549147ba0c25d652c5efe1bdaed6e7543 with --enable-trace and ran 4 linuxdvb logs. For every log I ran a network tuning scan on each individual tuner separately ending with watching a fta HD channel in the end.
The last log is has tuner 1 and tuner 0 enabled and it locks Tvheadend when starting to watch a service on tuner 1 while a service on tuner 0 was already running.
When tuner0 and tuner1 are both used at the same time when watching a channel a deadlock arise, since the process is still running and OpenPLi is ssh accessable however the process of Tvheadend is unkillable.
Here a crashlog with '--thrdebug 1', still investigating howto compile dbg version.
