ccls doesn't see definitions in headers

[mdaum-adsk]

#include <string>
std::string s{};

In emacs flycheck I get the error "ccls: no type named 'string' in namespace std". Same with types defined in <cstdint>.

[mdaum-adsk]

Hmm. Actually seems to be any header at all.

This poodle exhibits both behaviours. And shows the compile commands in play.

You should go https://github.com/MaskRay/ccls for help.

This is the resource dir line from the log file:

09:09:42 initialize.cc:328 I use -resource-dir=/usr/local/Cellar/llvm/7.0.1/lib/clang/7.0.1

And that clang doesn't seem to have the C++ headers there.

Turns out the system headers are a separate problem from the local headers. Local header problem I have managed to fix on the CCLS side.

@mdaum-adsk flycheck is noisy, now lsp have used flymake (emacs-lsp/lsp-mode@47f30a1) instead.

try launch ccls with -init='{"clang":{"extraArgs":["-isystem", "/Library/Developer/CommandLineTools/usr/include/c++/v1"]}}'
that wrok for me
