how to add c++11 support to syntastic vim plugin?

Question

I am using syntastic in my c++11 project. When I am editing in vim, and save (:w) the syntastic plugin gives me errors on every initializer list {} and for each loops which are clearly c++11 features that it's missing.

I installed syntastic using pathogen.

Here are two examples of the error I am getting on initializer lists and for each loops (both c++11 that compile fine):

Answer 1

Turns out the C++ linter (syntax checker) of syntastic has many options that can be set on your .vimrc (unfortunate, I wish it was project specific, like the .clang_complete solution).

To enable c++11 standards and use the libc++ library with clang (which is what my project is using) I added the following lines to my ~/.vimrc

let g:syntastic_cpp_compiler = 'clang++'
let g:syntastic_cpp_compiler_options = ' -std=c++11 -stdlib=libc++'

it now works beautifully.

Answer 2

I was facing the same problem and I insist to process c++98 and c++11 separately. below is my solution:

create file named gcc.vim under bundle/syntastic/syntax_checkers/cpp11/ and copy these to it:

    let g:syntastic_cpp11_compiler = executable('g++') ? 'g++' : 'clang++'

    \ 'name': 'gcc' })

let &cpo = s:save_cpo
unlet s:save_cpo

" vim: set et sts=4 sw=4:

that will make gcc checker available (want other checker? you can do the similar things i did for yourself) for files with &filetype == 'cpp11' in vim. how to make your files automatically recongnized as cpp11 filetype in vim? just create file named ext_detect.vim under ~/.vim/ftdetect/ with the following content:

au bufnewfile,bufread *.cpp11 set ft=cpp11
au bufnewfile,bufread *.cppx set ft=cpp11

by this way, you can process your *.cpp files as c++98 standard and *.cpp11 or *.cppx as c++11 standard separately, not only syntax checking, but also syntax highlighting (if you need cpp11 syntax highlighting support, this vim plugin will be useful, although not perfect).

Answer 3

It has project specific options, like the .clang_complete solution

You can set path to files g:syntastic_cpp_config_file and g:syntastic_c_config_file. The default is .syntastic_cpp_config for C++. Put file in root of the project and compiler options inside it (one for each line)

Answer 4

If your using YouCompleteMe in addition to Syntastic you need to change your .ycm_extra_conf.py file. Sepcifically change '-Wc++98-compat' to '-Wnoc++98-compat'.

I didn't have to change the Syntastic settings myself, although that might be because I'm using a compile_commands.json file.

Answer 5

If you use YouCompleteMe,maybe you should change '.ycm_extra_conf.py'.only change flags:(file path~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py) ;

 flags = [
 '-std=c++11',
 '-O0',  
 '-Werror', 
 '-Weverything', 
 '-Wno-documentation', 
 '-Wno-deprecated-declarations', 
 '-Wno-disabled-macro-expansion', 
 '-Wno-float-equal', 
 '-Wno-c++98-compat', 
 '-Wno-c++98-compat-pedantic', 
 '-Wno-global-constructors', 
 '-Wno-exit-time-destructors', 
 '-Wno-missing-prototypes', 
 '-Wno-padded', 
 '-Wno-old-style-cast',
 '-Wno-weak-vtables',
 '-x', 
 'c++', 
 '-I', 
 '.', 
 '-isystem', 
 '/usr/include/',
