Hi list,
I'm co-maintaining a C++ library that has been continuously updated in
CentOS 7 but a recent change made it incompatible with the default GCC
version available in el7. I.e. the next release (scheduled for the end
of 2019) will FTBFS in CentOS/RHEL 7.
Would it be fine to require a gcc version from a SCL to build this
library? I'm afraid that due to the nature of C++'s non-standardized ABI
it would require all dependent packages to be rebuild with gcc from the
SCL too.
Software Collections GCC is configured to follow C++ ABI from system
GCC. This puts some limitations on the libstdc++ shipped by SCL GCC,
but allows us to avoid that problem entirely.
If you're talking about the devtoolset version of GCC, that's not
strictly true. There are limitations on what is supported, so the
problem isn't avoided entirely.
