5 years ago The issue happen even with this example:
#include <stdio.h>
class A {
public:
int a;
int b;
};
int main(){
A* a= new A();
a->b =12;
printf(" hello %d %d \n",a->a,a->b);
return (0);
}

First thanks for doing that, still didn't find a c++ LSP that works I'm a user of vscode+clangd 10 LSP and I'm not happy so wanted to try out ccls. I have 5 min experience with ccls so forgive me if I missed something
I didn't manage to run it as a standalone mode
vscode configuration:
vscode - log
compile_commands.jsonor.cclsproject can be found here https://github.com/cisco-system-traffic-generator/trex-core
(https://github.com/MaskRay/ccls/wiki/Project-Setup))
Reduce to A minimal set of
.c.cc.h.hhfiles that can still demonstrate the issue.Consider a screencast gif.
