Hi, folks,
It seems I can't run a version of calibre newer than 3.23 without at least one library from gcc-5 (and the calibre attitude seems to be "screw you, 4's ancient, move to another distro").
I've added the scl repo - what devtoolset do I need to install?

Do you mean GCC 4.8.5 from CentOS 7, or GCC 4.47 from CentOS 6, or GCC 4.2.1 from CentOS 5?
If we’re talking about CentOS 6, then even Red Hat agrees with the Calibre folks: it’s now officially past time to get off CentOS 6, as of last week. CentOS 5? That and 3-4 years gone now.
If you’re speaking of CentOS 7, then we’re talking about a 5-year-old compiler, which I wouldn’t call “ancient,” but I’m not surprised that pre-built unofficial binaries aren’t targeting it any more, either.
A key pillar of the 10 year support value proposition is that the providers of the toolchains will be building new ancillary packages for you with those tools, but that only applies for packages in the distro. I don’t see how you can expect that non-Red Hat organizations would be constrained in the same way. They didn’t agree to that deal.
I suggesting that you build Calibre yourself, or find someone who has done so atop CentOS 7.
Beware: the most recent major release of Calibre also requires Python 3. They finally cut off all Python 2 support.
Alternately, upgrade to CentOS 8, which uses GCC 8.

I 100% agree with Warren.
When my users really want newer compiler on "not the latest" CentOS (say, they need c++11 features), I just download gcc version that satisfies them, compile, and install it into separate place, like, e.g., /usr/local/gcc620. And that makes them happy.
I hope, this helps.

That was the answer I was looking for. Unless it puts the libraries in the std. locations, I assume I'll have to set a modified PATH for calibre, but sounds good.
Thanks!
