[cfe-dev] ld linker error using clang analyzer checker

[Aleksei Sidorin via cfe-dev]

Hello,

It looks like clang is thinking that he has to compile the file because 
the default behaviour was not changed via cmdline options. Could you try:

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

? --analyze will tell clang that he doesn't need to produce binary, only 
to analyze the file.
