[Caml-list] Conflict between .../caml/config.h and Cocoa Security.framework

[Caml-list] Conflict between .../caml/config.h and Cocoa Security.framework

[John Velman]

I'm feeling my way into using OCaml to provide calculations for a Cocoa
application for OS X  using XCode on an iMac. I'm totally new at OCaml.
I'm working with the example in the manual, section 18.8 as a basis.

After taking small steps via plain C versions, finally, I made a simple
cocoa app with entry an entry field for an integer, and a value field for
the fibonacci value for the entry.

Compiliation failed due to an inconsistency between
/usr/local/lib/ocaml/caml/config.h and cocoa's ...Security.framework/cssmconfig.h
Specifically in this sequence:

#if defined(ARCH_INT64_TYPE)
typedef ARCH_INT64_TYPE int64;
typedef ARCH_UINT64_TYPE uint64; 
#else ...

Here the typedef for uint64 is in conflict with the framework's typedef  in
cssmconfig.h:

#ifndef _UINT64
typedef uint64_t uint64;
#define _UINT64
#endif


Here is the complete XCode compilation error output:

------  Compile error output:

/usr/local/lib/ocaml/caml/config.h

The "here" refers to the file cssmconfig.h in the cocoa Security.framework.


I did a temporary fix by commenting out the typedef for uint64 in .../caml/config.h,
and everything worked fine.  But this probably isn't the right solution!

Further info:

Using XCode 4.2 with Mac OS X Lion 10.7.4.

When I installed OCaml, I used the source ocaml-3.12.1.tar.   I did
configure with no options.  I followed the instructions in the INSTALL file
exactly (as far as I can tell!).


Best,
