I do wish to reiterate my desire for a std=98|03|11|14|1z parameter for ./b2. I think users get confused - as you can see on stackoverflow - on how to build Boost for C++ 11 or 14 or 1z. A simple
./b2 toolset=clang std=14
... I think is clear and obvious and memorable.
Hmmm currently I use b2 toolset=clang cxxflags=-std=c++03 is that so bad?
1. That command wouldn't work on MSVC. In documentation you have to keep saying "If using MSVC use the b2 command, else use this other b2 command". This is confusing for users. 2. You need std=XX put into the path generated inside bin.v2 to disambiguate binaries built using different std. Using cxxflags lets differing even incompatible binaries mix. This can be confusing. Even I have seen weird link errors at times, and realised only after some head scratching it's because I'm using a non-C++ 11 Boost and I accidentally typed the MSVC b2 command form on POSIX without thinking. What I would really prefer is a failure to find a library at all when I use mismatched std=XX config.
