Is it safe to build boost with default flags and link it to an application using c++20 standard. Boost uses c++11 as default option. I'm using gcc 11.1

  • It depends, some libraries might have a different ABI under different language versions – Alan Birtles Apr 08 '23 at 09:16
  • Is it the case for boost? – Peter Apr 08 '23 at 09:38

    It can be, you'll need to study the documentation for each library – Alan Birtles Apr 08 '23 at 09:39
  • How is this question different than [the duplicate](https://stackoverflow.com/questions/46746878/is-it-safe-to-link-c17-c14-and-c11-objects) of [the question you asked yesterday](https://stackoverflow.com/questions/75956597/abi-compatibility-between-gcc-7-1-and-gcc-11-1)? (In fact, this question looks like a better match to that duplicate than what you asked yesterday, since yesterday's question brought in different compiler versions.) – JaMiT Apr 08 '23 at 12:33

    If you want to ask something new, maybe you would be interested in asking how you could specify a language standard when building Boost? (I'd also suggest mentioning at least one of the libraries for which you need something compiled, since much of Boost is header-only.) – JaMiT Apr 08 '23 at 12:36
  • I want to build boost thread. isn't dangerous to use c++ 11 compiled lib with application code compiled with c++20 – Peter Apr 08 '23 at 14:43
