Hello,
In general, is it recommended to recompile when switching between
binary-compatible GCC versions? I understand that, in specific
situations, it will depend on many factors, but I am hoping to get a
sense of what is recommended for most cases.
Specifically, what prompted me to ask this question is the presence of
several *.la files in the installation directory trees of the GCC
versions that I have built. Packages that use autotools to build pick up
on these files and end up doing a few things that tie that package to
the particular path of that installation (such as setting RPATH to that
path). This makes changing out the version of GCC, e.g., from 5.2.0 to
5.3.0, problematic for those packages. Should trying to "reuse" a build
of a package against more than one version of GCC be avoided?
Thanks,
David
