scan-build doesn`t get the null pointer

[mtxing69]

ubuntu16.04, scan-build ver 3.8
in 04-static-analysis/clang-analyzer, cmake is normal, but in make progress, the expected "null pointer" didn`t get out, instead there is a "iostream file not found"

Anybody knows why?

It's possible that different versions of scan build report different errors. Once you can call scan build and see results from it then your project is setup correctly
