This seems like a configuration issue with your editor, and not a problem with Bitcoin Core. I have used compiledb to generate a compile_commands.json before, see here: https://github.com/fanquake/core-review/blob/master/clang-tools.md#generating-a-compilation-database, however we have no official documentation relating to its usage, or for editor configuration.

@fanquake thanks for your mention. I have solved this problem by following website: https://stackoverflow.com/questions/61150687/how-to-add-include-path-for-language-servers-in-coc-settings-json-file

"initializationOptions": {
"cache": {
"directory": "/tmp/ccls"
},
"clang": {
"extraArgs": [
"-I",
"/opt/ros/kinetic/include/"
]
}
}

the MAIN REASON is coc.vim setting is incorrect about ccls;
