Description Dennis Schridde 2014-12-07 13:03:05 UTC 
Mesa 10.3.4 / LLVM 3.5.0 / libclc 0.0.1_pre20141027 seems to be unable to compile the OpenCL function S2KItSaltedSHA1Generator from current John-The-Ripper Git [1].

The function is too long to quote here, but the signature is:
inline void S2KItSaltedSHA1Generator(__global const uchar *password, int password_length, __global const uchar *salt, int count, __global uchar *key, int length)

My hardware as reported by JTR is:

I've also run into this issue, although a workaround exists (see: https://github.com/magnumripper/JohnTheRipper/issues/2204).  The problem appears to be with the declaration of 'inline'; removing the 'inline' declaration fixes the compilation issue.
