Please make sure you use

Please make sure you use libraw.h (and other include files) for the same version: internal layout changes from version to version, there is no binary (ABI) compatibility between LibRaw 0.17 and (say) LibRaw 0.18 (unless you use C-API only).

If version mismatch is *not* problem cause, I do not have any other ideas.
