There's no Objective-C runtime in the clang project. There are a few C and C++ ones, but no Objective-C one. So, I tried using the GNU runtime (libobjc2, downloaded from github), and it compiled, but with a lot of warnings. However, I'm not sure it should issue all those warnings, because when I try to compile a simple project, after typing make, I get the following output:
```D:/Developer/LLVM/bin/clang.exe -I.. -std=c17 -fblocks -fobjc-exceptions -Wno-objc-root-class -c kObject.m
D:/Developer/LLVM/bin/clang.exe -I.. -std=c17 -fblocks -fobjc-exceptions -c kException.m
D:/Developer/LLVM/bin/clang.exe -I.. -std=c17 -fblocks -fobjc-exceptions -c kString.m
D:/Developer/LLVM/bin/clang.exe -I.. -std=c17 -fblocks -fobjc-exceptions -c kBool.m
D:/Developer/LLVM/bin/clang.exe -I.. -std=c17 -fblocks -fobjc-exceptions -o test.exe test.m kObject.o kException.o kString.o kBool.o -lobjc

clang: error: linker command failed with exit code 1227 (use -v to see invocation)

```
Did I do something wrong, or is this a bug?
