Thankyou both,

However I am still receiving errors.

When running:
./john --format=grub-opencl -t

I get:
Build log: <program source>:219:16: warning: comparison of integers of
different signs: 'int' and 'unsigned int'

        for (i = 0; i < keylen; i++)

             ~ ^ ~~~~~~

<program source>:258:11: warning: comparison of integers of different
signs: 'unsigned int' and 'int'

        for(i=0;i<saltlen;i++)

         ~^~~~~~~~

<program source>:351:24: warning: comparison of integers of different
signs: 'int' and 'unsigned int'

        for (round = 1; round < rounds; round++) {

                 ~~~~~ ^ ~~~~~~


Benchmarking: grub-opencl, grub-opencl [PBKDF2-SHA512]... FAILED
(get_hash[0](0))


When I try it out with the test I provided here earlier, I get

Self test failed (get_hash[0](0))


It could well be my fault, so here's my exact process:

Download latest bleeding-jumbo (without modifying anything), Launch terminal

cd into /src

build macosx-x86-64-opencl

wait for completion, no errors,

then cd into /run.


Thanks,

Joe.
