Using device 1: ATI Radeon HD 6770M OpenCL error (UNKNOWN ERROR :() in file (common-opencl.c) at line (39) - (Source kernel not found!) Looks like "john" was found via PATH, in which case argv does not give the path to the run directory... or/and maybe the directory did not contain the OpenCL kernels in this specific case. I am not sure what we want to do about this, if anything. For non-system-wide builds/installs, we can simply state that "john" should be invoked with the path specified (at least relative to cwd) - e.g., "./john" in the run directory or "../run/john" if invoking from src. We'll need to support system-wide installs with OpenCL kernels, though. I recall that this topic was brought up on john-users in Gentoo package context, but I don't recall whether there was any conclusion or determination. Alexander
