Hi,

I was trying to integrate the static analysis tools into a few of my
projects.
I started using scan-build, and couldn't  get it working on larger
projects,
even after exporting CXX & CC variables.
It just always reported 'no bugs found'.
Using clang++ --analyze, I was able to see warning messages.

On the smaller projects, I noticed that the errors were the same for both
the
compiler argument(--analyze) and the scan-build command.
Would anyone know if and how they would incur different warning reports?


Thanks!
-Cyndy Ishida

I would recommend looking at the build script to see if there are any
errors
and if the source files where you expect errors to occur are being
analyzed.
(If it’s a makefile project, do not forget to run scan-build configure.)

Cheers,
Anna
