To build from source you need MacOS 10.12 (Sierra) or higher to get a version
of Xcode with a sufficiently-new Clang.
To build using MacPorts Clang add CMake flags
```sh
-DCMAKE_CXX_COMPILER=clang++-mp-6.0
-DCMAKE_PREFIX_PATH=/opt/local/libexec/llvm-6.0
```
See https://github.com/MaskRay/ccls/issues/512 , use a [shell script wrapper](Install#shell-script-wrapper):
Homebrew clang is a bit different from `/usr/bin/clang`.
Invoke `clang++ -xc++ -fsyntax-only -v /dev/null` to get a list of C/C++ search paths.
Add them as `-isystem` into the [shell script wrapper](Install#shell-script-wrapper). For example:
```sh
#!/bin/sh
exec /path/to/ccls/Release/ccls -init='{"clang":{"extraArgs":["-isystem", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include"]}}' "$@"
exec /opt/homebrew/bin/ccls --init='{"clang":{"extraArgs":[
"-isystem/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1",
"-isystem/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/12.0.5/include",
"-isystem/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include",
"-isystem/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include",
"-isystem/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks"
]}}' "$@"
```
With clang < 8, `"-isystem", "/Library/Developer/CommandLineTools/usr/include/c++/v1"` is also needed (https://github.com/MaskRay/ccls/issues/191#issuecomment-453809905)
With most recent MacOSs(e.g. Catalina 10.15.2), one more clang.extraArgs is needed to make ccls work properly (https://github.com/MaskRay/ccls/issues/512#issuecomment-545575369)
