Hi,
After a bit of poking around with nm in various objects I determined
that the baseline_symbols files define what should be exported. The
following grep+sed combo adds the necessary export for any architecture
that exports the C1 constructor symbol.
grep _ZNSsC1EOSs libstdc++-v3/config/abi/post -R -l | xargs sed -i.bak
'/_ZNSsC2EPKcRKSaIcE/ iFUNC:_ZNSsC2EOSs@@GLIBCXX_3.4.14'
For sure the baseline_symbols files do *not* define what is exported,
pre/gnu.ver does, those files are only for checking purposes. Now, I'm
traveling and I'm not a position to carefully double check on Linux what
you are saying, I'm going to ask Jakub' help here, looks more likely
something should be additionally exported @GLIBCXX_3.4.15.
Paolo.
