c++ - How can I fix YouCompleteMe's wrong error highlighting of "cout" usage? -

i've been trying youcompleteme set on machine, , i'm there, except small problem. when use cout simple cout << "hello world!" << endl;, ycm highlights cout, first <<, , string error, telling me: invalid operands binary expression ('ostream' (aka 'int') , 'const char *').

i know program correct. compiles , runs. causing behavior?

let me know if left out information.

thanks!

edit: .ycm_extra_conf.py file this:

i forgot commas on end of lines telling ycm find libraries. corrected flags read:

flags = [ '-wall', '-stdlib=libc++', '-std=c++11', '-x', 'c++', #'-x', 'c++-header' # path work on os x, paths don't exist not # harmful '-isystem', '/applications/xcode.app/contents/developer/toolchains/xcodedefault.xctoolchain/usr/bin/../lib/clang/7.0.2/include', '-isystem', '/applications/xcode.app/contents/developer/toolchains/xcodedefault.xctoolchain/usr/include', '-isystem', '/applications/xcode.app/contents/developer/platforms/macosx.platform/developer/sdks/macosx10.11.sdk/usr/include', '-isystem', '/applications/xcode.app/contents/developer/platforms/macosx.platform/developer/sdks/macosx10.11.sdk/system/library/frameworks', '-isystem', '/system/library/frameworks/python.framework/headers', '-isystem', '../llvm/include', '-isystem', '../llvm/tools/clang/include', '-i','.', '-i','./clangcompleter', ] 

anyways, learned lot of googling did, it's not complete loss. tried help!
