As of 22.06.2019 - linux debian will receive next stable version in few version and its GCC will upgrade from 6.3 to 8.3. Ubuntu 18.04 supports GCC 7.4, [AVS] currently uses GCC 7.3.
Scripting branch breaks VS 2015 compatibility by (bug/lack of C++ feature/whatever) in ERM parser. VS 2017 (MSVC 19.1x) has way better C++ support and there is almost no reason to still use 2015.
If we assume GCC 7.3 (GCC 7) as minimal supported GCC version then on GCC part we can use:
- full C++14
- almost full C++17, with exception of few features listed below, with optional examples of related standard library elements in braces:
- Polymorphic memory resources (<memory_resource>)
- C++17 should refer to C11 instead of C99
- Elementary string conversions (std::to_chars, std::from_chars, chars_format)
- Standardization of Parallelism TS
- File system library (std::filesystem)
- Template argument deduction for class templates - only partial support, probably conforms to v1 / draft paper?
- std::char_traits<char> and std::char_traits<wchar_t> in constant expressions.
There is no guarantee this is everything, travis CI should help. If somebody uses "not fully supported" feature on purpose he should let others know in PR description / slack etc.
