Eclipse Oxygen error "Bad Character" at the new C++14 digit separator

#define FOO 1'000 triggers this Eclipse Oxygen warning:

Bad character sequence encountered: '000

gcc 7.3 compiles it of course fine.

I set under Project -> Properties -> C/C++ Build -> Settings -> Dialect -> Other dialect flags the value -std=c++17.

What am I missing in order Eclipse does not show this warning? Due to this warning all references using FOO are not resolved and this results in other errors displayed by Eclipse.

Solution

  • Eclipse has its own C++ parser, and it doesn't have complete support for C++14 and C++17 features yet.

    Bug 519062 tracks support for C++14 digit separators.
