Yes. Eventually we'll have to clear the road for this. However,
I don't think we'll ever want to support a mixed abi system.
Can we, even? Would it be a mixed-abi system or a multi-abi system?
The correct thing for upstream to do is to bump the soname. But right
now, we have:
readelf -d /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/libstdc++.so.6.0.17 |
grep SONAME
readelf -d /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.2/libstdc++.so.6.0.18 |
grep SONAME
readelf -d /usr/lib/gcc/x86_64-pc-linux-gnu/4.9.1/libstdc++.so.6.0.20
| grep SONAME
all yielding
0x000000000000000e (SONAME) Library soname: [libstdc++.so.6]
