[OpenAFS-devel] Building 1.5.1 on Linux (FC3)

[Simon Wilkinson]

Hi,

Just wondering if anyone has tried building OpenAFS 1.5.1 on Linux, or if
I'm missing something blatantly obvious...

I'm seeing a problem with conflicting definitions of encrypt() (in 
des/crypt.c) when building libafsrpc

The culprit seems to be the following change that went in as part of the 
demand/attach fileserver changes...

This results in the definition of __USE_XOPEN, which in turn causes 
/usr/include/unistd.h to include its definition of encrypt(), which has a
different prototype to the AFS one.

Backing out this change solves the compilation problem.

Cheers,

Simon.
