I wasn't aware that rebuilding with g++-6 caused ABI changes. Do you know if this affects other libraries? Surely we can workaround it in boost by doing the 1.61 transition at the same time, but what about other libraries? > Therefore we > would like to only support boost1.61 abi, when compiled with gcc-6.

Can't we do GCC 6 + boost1.61 first, then do icu later? What is the benefit of doing them together, apart from saving a few cycles in the buildds? Is icu also affected by the ABI break when rebuilt with g++-6 ? > Please let me know if you are happy to transition to > boost1.61(gcc-6,icu57), and let me know when we can coordinate the lot. Have you done any test rebuilds against boost1.61 (with GCC 6)? Once all the above is clear, I think we are ready to start anytime now. > A boost tracker similar to the past boost trackers would be useful, once > the transtion starts. See https://release.debian.org/transitions/html/boost1.61.html (will appear in 20 minutes). Cheers, Emilio
