Hello!

Yes, we're dropping support for such an old GCC, mostly because we don't have enough resources (time) to manage those old systems for testing. Other problems are with lack of support of some C11 features. I should also say that the upcoming multithreaded versions will also need a reasonably new compiler to support thread local storage and maybe C11 atomics also.

Sorry for that. We try our best, yet keeping backwards compatibility with old systems is quite a lot of work for us.

BTW you can still use your old GCC to build a newer GCC or Clang locally and then build BIRD using that compiler, however it is in most cases an insane overkill.

Hi Robert,

thanks for the answer. I already assumed such an issue :(
I'm aware of the EOL in November, but I'm afraid  I still need to roll
it out up to that date.

Thanks for your quick answer. I will go with Bird 1 in that case.

Regards, Tim

I'm happily using Bird 2 on multiple CentOS 7 nodes. Sadly I now need to
rollout BGP to some CentOS 6 boxes :sadface:. I noticed that
ftp://bird.network.cz/pub/bird/centos/ only contains CentOS 7 packages,
and EPEL 6 only has Bird 1.6.8. However I wanted to ask if Bird 2 would
work on CentOS 6? Would Bird itself compile but dependencies are
outdated/missing?

since BIRD 2.0.5, a C compiler newer than contained in CentOS 6 is needed;
I had to drop BIRD 2 from EPEL 6 due to this. See also the old thread here:

 - http://trubka.network.cz/pipermail/bird-users/2019-August/013634.html
 - http://trubka.network.cz/pipermail/bird-users/2019-August/013631.html

But given CentOS 6 reaches end of lifetime in November (!), please migrate
these boxes to CentOS 8 or at least 7. There, BIRD 2 is even in EPEL :)


Regards,
  Robert
