If the issue is simply invoking the linker, then you can do:

> clang -Xclang -analyze -Xclang -analyzer-checker=checker_name -fsyntax-only test.c

OR

> clang —analyze -Xclang -analyze -Xclang -analyzer-checker=checker_name test.c

(note the double dash before “analyze”)

I think both should work.
