This may be common knowledge to some, but it was new to me.
Libraries that use C++11 and are compiled with GCC 4.8.x that CentOS 7.x
has are NOT binary compatible with GCC 5.x or newer.
It seems to only effect C++11.
What you have to do -
create /opt/gcc55 (or whatever)
Rebuild any libraries that use C++11 that you need in something compiled
with GCC 5+ and install them within that prefix.
Then point to them in that prefix when building what you need to build.
-=-
The Linux runtime linker seems to get it right (as long as you have
/opt/gcc55/lib64 in path) and not load wrong version of library, so you
don't need to use rpath.
But you do need to have a version of the dependency compiled with the
GCC you want available at both compile time and runtime.
-=-
I ran across this issue when building Audacity 2.2.2 - which does not
build with GCC 4.8.5.
The problem libraries:
* flac
* vamp-sjdk-plugin
* wxGTK3
All three of those use C++11 and therefore needed to be rebuilt with GCC
5.5.0 (what I used for building Audacity)
Just thought I'd pass it along.
