huge project add clangd.fallbackFlag -I<dir> don't work #497

Closed CalebDu closed 1 year ago

CalebDu commented 1 year ago

because my huge project can't find some header file. I add -I flag in clangd.fallbackFlag. but i does not work. And in clangd extension "output" there is no "fallbackFlag" information. setting.json

  "clangd.fallbackFlags": [
    "-I/home/caleb.du/code/tops/build/3rdparty/clang_binary/src/lib/clang/11.0.0/include/",
  ],

HighCommander4 commented 1 year ago

clangd.fallbackFlags is only used for source files for which a compile_commands.json file cannot be found. In this case, clangd is successfully finding /home/caleb.du/code/tops/build/compile_commands.json, so fallbackFlags will not be used.

For adding an extra flag to the command from compile_commands.json, you can create a .clangd config file containing:

CompileFlags:
  Add: [-I/home/caleb.du/code/tops/build/3rdparty/clang_binary/src/lib/clang/11.0.0/include/]

See https://clangd.llvm.org/config.html#add for more details.
