Thanks, worked for me.

Though, upstream should figure out, what went wrong with setting
$RealBin correctly, as not all systems use `/usr`.


Thanks,

Bug#698352: `scan-build: error: Cannot find an executable 'clang' relative to scan-build.`

Package: clang
Version: 3.2-1~exp1
Severity: normal
Control: found -1 3.2-1~exp5


Dear Debian folks,


`scan-build` [1] does not work out of the box.

$ scan-build make
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.

Passing the path to Clang as written in the explanation, it works.

$ scan-build --use-analyzer=/usr/bin/clang make


Thanks,

Paul


PS: The option `--use-analyzer` is not mentioned in the help output
(`--help`) and neihter in the manual.
