Hi Beowulfers: What do you folks use (besides use Singularity or similar) for software that for whatever reason balks because it asks for GLIBC/GLIBCXX 3.4.20 or newer on CentOS 7.x?
From what I’ve read, it’s not safe to build it in an alternate location and use
LD_LIBRARY_PATH to have software call it. I am almost certain that this is true
of the GLIBC dependencies. I’m less sure of the GLIBCXX dependency. And I know
that whenever we build an alternate copy of GCC (like 4.9.x or newer), we
create a software module that /does/ in fact place a newer libstdc++.so.6 into
the LD_LIBRARY_PATH. What I’ve read /might/ be safe, but problematic in some
cases (and no help at all in the case of binary distributions) is using -rpath
type stuff at build time. There appears to be a lot of conflicting information
out there, and some “just throw a newer libstdc++.so.6 library in a lib
directory,” and some “that’s not such a great idea” posts right below them.
Do I misunderstand the situation? Is there a difference between software that
demands a newer GLIBC vs. GLIBCXX? Does anyone have a reference one can trust
on this subject?
Thanks -- I know there are some really highly qualified people on this list. :-D
