Details

Description:
scan-build is a symlink from /usr/bin/scan-build to /usr/lib/clang-analyzer/scan-build/scan-build. Running `scan-build gcc ...` gives:

scan-build: error: Cannot find an executable 'clang' relative to scan-build. Consider using --use-analyzer to pick a version of 'clang' to use for static analysis.

I expected something like:

scan-build: Using '/usr/bin/clang' for static analysis
...

The attached patch gives an idea of where a hard-coded patch can be included. An alternative (tested too) is creating a symlink /usr/lib/clang-analyzer/scan-build/clang -> /usr/bin/clang.

Version: clang-analyzer 3.2-3
   absolute-path.patch (0.6 KiB)

This is something that broke in 3.2; 3.1 and earlier had a fallback: "scan-build: Using 'clang' from path: /usr/bin/clang"

Thanks for the report; will fix it using your alternate symlink method. :)
