[Bug 8202] I get no reports from running "scan-build <args...> make -k"

I got this response from a bug report filed about the scan-build tool
not doing the static analysis:

(In reply to comment #0)

When I run "clang --analyze" on my c++ source files individually I get reports,
but none when using the scan-build tool.

This is intended behavior. C++ support is still alpha and so it isn't enabled
by default in scan-build. It's really only intended to be used by those
currently hacking on the analyzer.

If you want to enable C++ analysis, you must define the environment variable
CCC_ANALYZER_CPLUSPLUS.

It works with 'clang --analyze' because that's not intended to be a public way
to use the analyzer. It should probably be disabled there as well. In the
future that flag may go away as the analyzer evolves to do cross-file analysis.

I tried setting CCC_ANALYZER_CPLUSPLUS but still no go.

If one wants try the static analysis on a set of project c++ source
files, what is the correct way to do it?

Thanks,

Hi Tom,

Where did you define the environment variable? Also, does 'c++-analyzer' exist? We can take this off the list; can you email me the output you are seeing from scan-build?
