Compatible with YouCompleteMe and Syntastic?

Question

I want to make YouCompleteMe do some refinements and Syntastic to check for errors, but it looks like they don't match.

When YouCompleteMe is disabled, Synatstic works, and vice versa. but when both are on, the termination does not work, and the syntax does not show any errors.

What configuration do I need to make this work?

here are my options: (note scroll down to see all options)

" " YouCompleteMe options " let g:ycm_register_as_syntastic_checker = 1 "YCM will put icons in Vim gutter on lines that have a diagnostic set. "Turning this off will also turn off the YcmErrorLine and YcmWarningLine "highlighting let g:ycm_enable_diagnostic_signs = 1 let g:ycm_enable_diagnostic_highlighting = 0 let g:ycm_always_populate_location_list = 1 "default 0 let g:ycm_open_loclist_on_ycm_diags = 1 "default 1 let g:ycm_complete_in_strings = 1 "default 1 let g:ycm_collect_identifiers_from_tags_files = 1 "default 0 let g:ycm_path_to_python_interpreter = '' "default '' let g:ycm_server_use_vim_stdout = 0 "default 0 (logging to console) let g:ycm_server_log_level = 'info' "default info let g:ycm_global_ycm_extra_conf = '' "where to search for .ycm_extra_conf.py if not found let g:ycm_confirm_extra_conf = 1 let g:ycm_goto_buffer_command = 'same-buffer' "[ 'same-buffer', 'horizontal-split', 'vertical-split', 'new-tab' ] let g:ycm_filetype_whitelist = { '*': 1 } let g:ycm_key_invoke_completion = '<C-Space>' " " syntastic settings " let g:syntastic_enable_signs = 1 let g:syntastic_auto_loc_list = 1 let g:syntastic_check_on_open = 1 let g:syntastic_always_populate_loc_list = 1 let g:syntastic_cpp_checkers = ['gcc'] let g:syntastic_auto_jump = 1 let g:syntastic_enable_balloons = 1 let g:syntastic_cpp_compiler = 'g++' let g:syntastic_cpp_compiler_options = '-std=c++11 -Wall -Wextra' let g:syntastic_cpp_check_header = 1 let g:syntastic_cpp_auto_refresh_includes = 1 "let b:syntastic_cpp_cflags = '-I/home/user/dev/cpp/boost_1_55_0' let g:syntastic_cpp_include_dirs = [ \ '/opt/boost_1_55_0', \ '/opt/cryptopp-5.6.2', \ '/opt/llvm_install/include/llvm', \ '/opt/llvm_install/include/clang' ]

Here is my modified version of .vimrc (only YCM settings), so now YouCompleteMe works with all functions with these settings + I don’t need any syntax functions anymore, since this is not necessary, except for only 2 and automatic opening of the list of locations and automatic switching to errors.

 " " YouCompleteMe options " let g:ycm_register_as_syntastic_checker = 1 "default 1 let g:Show_diagnostics_ui = 1 "default 1 "will put icons in Vim gutter on lines that have a diagnostic set. "Turning this off will also turn off the YcmErrorLine and YcmWarningLine "highlighting let g:ycm_enable_diagnostic_signs = 1 let g:ycm_enable_diagnostic_highlighting = 0 let g:ycm_always_populate_location_list = 1 "default 0 let g:ycm_open_loclist_on_ycm_diags = 1 "default 1 let g:ycm_complete_in_strings = 1 "default 1 let g:ycm_collect_identifiers_from_tags_files = 0 "default 0 let g:ycm_path_to_python_interpreter = '' "default '' let g:ycm_server_use_vim_stdout = 0 "default 0 (logging to console) let g:ycm_server_log_level = 'info' "default info let g:ycm_global_ycm_extra_conf = '~/.ycm_extra_conf.py' "where to search for .ycm_extra_conf.py if not found let g:ycm_confirm_extra_conf = 1 let g:ycm_goto_buffer_command = 'same-buffer' "[ 'same-buffer', 'horizontal-split', 'vertical-split', 'new-tab' ] let g:ycm_filetype_whitelist = { '*': 1 } let g:ycm_key_invoke_completion = '<C-Space>' nnoremap <F11> :YcmForceCompileAndDiagnostics <CR> 

I can also add that in order for YCM to work with full support, I built the following source:

Vim from source + all the latest fixes applied in the source before assembly. The llvm + clang libraries (latest stable) built from source. YCM is built with support for fresh clang libs again.

It is also important to customize the .ycm_extra_conf.py file. (flags and mainly include) here are the mines: (scroll down if you want to see them all)

 flags = [ '-Wall', '-Wextra', '-std=c++11', 'c++', #Standard includes '-isystem', '/usr/include/c++/4.7', #GTK includes '-isystem', '/usr/include/gtk-3.0', '-isystem', '/usr/include/glib-2.0', '-isystem', '/usr/include/glib-2.0/glib', '-isystem', '/usr/lib/i386-linux-gnu/glib-2.0/include', '-isystem', '/usr/include/pango-1.0', '-isystem', '/usr/include/cairo', '-isystem', '/usr/include/gdk-pixbuf-2.0', '-isystem', '/usr/include/atk-1.0', '-isystem', '-I/usr/include/gio-unix-2.0', '-isystem', '-I/usr/include/freetype2', '-isystem', '-I/usr/include/pixman-1', '-isystem', '-I/usr/include/libpng12', #current dir '-I', '.', #custom libraries '-I', '/opt/boost_1_55_0', '-I', '/opt/cryptopp-5.6.2', '-I', '/opt/llvm_install/include' ] 

If you use GTK + encoding, this list may help you. By the way, if you are wondering what this system means before turning on dir, it means that YouCompleteMe (the clang / clang ++ compiler) now displays warnings and errors from these headers. (which are false positive in 99% of cases)

btw, the Sinastic check is done using the clang compiler (background compilation), while its creation can be done with any kind of compiler, of course.

Thanks!
