Operating System

Linux 4.15.0-46-generic 16.04.1-Ubuntu SMP

gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04)

What went wrong

The ALE can‘t recognize the syntax of C++17. Even if I change the config to let g:ale_cpp_gcc_options = '-Wall -O2 -std=c++1z'

Reproducing the bug

My config as follows.

let g:ale_linters_explicit = 1
let g:airline#extensions#ale#enabled = 1
let g:ale_linters = { 'c++': ['clang', 'g++'], 'c': ['clang'] }

let g:ale_c_gcc_options = '-Wall -O2 -std=c99'
let g:ale_cpp_gcc_options = '-Wall -O2 -std=c++1z'

let g:ale_c_clang_options = '-Wall -O2 -std=c99'
let g:ale_cpp_clang_options = '-Wall -O2 -std=c++1z'

let g:ale_c_cppcheck_options = ''
let g:ale_cpp_cppcheck_options = ''

1. When I use the c++14, the ALE work correctly.
2. If I use the gcc or clang to compile the code, it works fine.

[w0rp]

The error is coming from clangcheck there, so you should either configure clangcheck or disable it.

[w0rp]

let g:ale_linters = {'c': ['clang'], 'c++': ['clang', 'g++']}

That's probably your issue. Try using 'cpp' instead of 'c++'.

[chiphell123]

It works! Thx.

I still have similar issues, added --std=c++17 to clang and g++ flags in .vimrc for ale, using the same flags to compile no warning issued, ALEInfo also showed no warnings, but vim still hints "Wc++17-extensions" warnings.
