`-D__STDC_FORMAT_MACROS` is because otherwise `mingw-w64-headers/crt/inttypes.h` does not define `PRIu64`. `-D__STDC_FORMAT_MACROS` is because otherwise `mingw-w64-headers/crt/inttypes.h` does not define `PRIu64`.
Try running `ccls.exe` once the above command finishes.
If you encounter `Entry Point Not Found` errors, it's most likely due to missing clang/stdc++ lib files.
Get a copy of `libclang.dll` and `libstdc++xx.dll` (xx is the version no.) from your `mingw64/bin/` and place them in your `ccls.exe` directory.
```sh
# Be sure to change libstdc++ version to the one you have in your mingw64/bin/ path
cp /mingw64/bin/libclang.dll /mingw64/bin/libstdc++-6.dll ~/ccls/Release/
