Vscode-cpptools: invalid operands to binary expression ('std::ostream' (aka 'int') and 'const char [2]')ccls(2)

Type: LanguageService

Describe the bug

• OS and Version: i use vscode remote development on my personal pc which is a win10, when the cloud dev machine(the project runtime environment) has a centos system.
  -- my pc: win10
  -- dev machine: Linux VM_110_148_centos
• VS Code Version: 1.44.2
• C/C++ Extension Version: 0.27.1
• Other extensions you installed (and if the issue persists after disabling them):
• Does this issue involve using SSH remote to run the extension on a remote machine?:
  yes, it does.
• A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc).
  just like the operations in this docs https://code.visualstudio.com/docs/cpp/config-linux, i learn to
  mkdir a helloworld, and write a testhello.cpp. Whereas, there is always has a code-check warning below the symbol <<(the last <<, actually), when i hover my cursor on this symbol, it displays

std::__1::ostream &std::__1::operator<<<...>(std::__1::ostream &__os, const char *__str) +18 overloads invalid operands to binary expression ('std::ostream' (aka 'int') and 'const char [2]')ccls(2)

then i click alt+f8, it show me

base specifier must name a classccls(2)
stl_vector.h(164, 20): in instantiation of member class 'std::_Vector_base<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >::_Vector_impl' requested here
stl_vector.h(210, 30): in instantiation of template class 'std::_Vector_base<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >' requested here
testhello.cpp(9, 20): in instantiation of template class 'std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >' requested here

Steps to reproduce

1. use the ssh func to connect the remote dec machine
2. create this helloworld project
3. paste these code in the following blank
   

1. it show me these code-check warning

but the strange thing is, this project still can be compiled and builded without any error.(it just a single cpp file, no multiple.)

@joseph102outlaw102 Those errors are not from our C/C++ extension. They appear to be from some ccls(2) extension?

Also, we don't know why @Answer-123 is posting strange messages.

Use Dev-cpp and this error won’t be happening

No, but it’s a better compiler.It uses GCC
