Yesterday I started making some project and today I check out that my compiler (mingw_w64) is the newest one which I find in Internet (8.1) but I don't have all functions from C++20. So maybe someone know how to figure out this? If it somehow help my IDE is QT creator.

  • Do you mean compiler g++? v8.1 is certainly not the latest version available on mingw – ravenspoint Apr 28 '21 at 18:35
  • Mingw-w64 appears to keep its own versioning scheme, per this site: http://mingw-w64.org/doku.php/start I don't know if it's the version people are using these days; I just avoid minGW if I can. – sweenish Apr 28 '21 at 19:01

C++ ISO standards and compilers do not progress at the same pace or with the same priorities. Also, C++ standards are available (drafts) before they are complete or officially published: quite often, compilers partially support the draft specs. The good side of this is that there are tables telling you what feature of a given standard is supported by a given version of GCC. You can find such a table for GCC here.

The current latest release of GCC is GCC 11 and C++20 support has been available since GCC 10.

Another compiler is LLVM/Clang, but I don't believe their C++20 support is on the same level as GCC yet, though I excpect it to catch up soon.
