Subject: Parallella: OpenCL

Hello,

I'm Rafael, the student from GSoC, today I added a arm32-opencl option to
the make file. In order to be able to compile it, I had to remove
"opencl_pwsafe_fmt" because if not it returns this linker error:

opencl_pwsafe_fmt.o: In function `get_salt':
opencl_pwsafe_fmt.c:(.text+0x432): undefined reference to `alter_endianity'


Now I have an executable of JtR but when I try to execute (as super user)
with the --test parameter, it returns the next error:

root@...allella-16:~/john-1.7.9-jumbo-7/src# ../run/john --test
[25320] clmesg CRITICAL: libocl.c(849): Linux mmap does not support

_libocl_clproc_state 0xb6fcc000
[25320] clmesg WARNING: libocl.c(149): cannot read ocl.conf, using ICD
fallback (/etc/OpenCL/vendors
Segmentation fault

It looks kind of similar to other error that I got in this example
http://forums.parallella.org/viewtopic.php?f=18&t=42

./out

I'm awaiting for help in the forum, I suppose that this is a problem with
the opencl sdk (libocl) and hopefully the same fix that solve the problem
with the example would sove the problem with JtR.

What I must to do now?.

Best regards,
Rafa.
