You have to use scanbuild: http://clang-analyzer.llvm.org/scan-build.html

You type the commands that generate your build, but you pre-pend them with scan-build.

Example: instead of

make

type

scan-build make

instead of

./configure
make

type

scan-build ./configure
scan-build make

Clear the build before launching the analyzer, otherwise make will state that everything has been built already and the analyzer will not run.
