Update (and apologies for the poor subject),

ukasz suggested copying the src/opencl_device_info.h. So I did. It has to be in ./, but that just leads me to a different error:

Kotai:JohnTheRipper chmullig$ ./run/john --format=agilekeychain-opencl --rules=WordlistOnly --wordlist=wl.txt openwall.hash
OpenCL platform 0: Apple, 2 device(s).
Device 1: GeForce GT 330M
Local worksize (LWS) 64, Global worksize (GWS) 9216
Loaded 1 password hash (1Password Agile Keychain PBKDF2-HMAC-SHA-1 AES [OpenCL])
Self test failed (cmp_all(1))


Running ./john -test worked fine until it got to the opencl section.

OpenCL error (CL_INVALID_CONTEXT) in file (opencl_nsldaps_fmt.c) at line (149) - (Error Unmapping outbuffer)


As an aside to future googlers who might encounter this or similar, ukasz saved me with this cpu-based workaround:

make clean && make macosx-x86-64
rm ../run/john
echo "extern struct fmt_main fmt_agile_keychain;" > fmt_externs.h
echo "john_register_one(&fmt_agile_keychain);" > fmt_registers.h
make macosx-x86-64 #WITHOUT CLEAN!!!

Thanks,
Chris
