Did you clean the built project before running scan-build again? Since scan-build interposes on calls to the compiler, if the build system doesn’t build a source file then scan-build won’t see it. This is a common pitfall — we should really mention this in the documentation for scan-build!

Also, don’t forget to run any ./configure script through scan-build as well so you don’t get hard-wired paths to the wrong compiler. <https://clang-analyzer.llvm.org/scan-build.html#recommended_autoconf <https://clang-analyzer.llvm.org/scan-build.html#recommended_autoconf>>
