Re: Objective C/C++

Hi!

Yes, it is the objective-c keywords that are not recognized by the MW
compiler. When -- or if -- I manage to pass the compilation phase I
will start to deal with the runtime issue. (-:

Sample objective-c code (compiles with gcc main.m -o x -lobjc):

// --------------------------------------------------------
#include <objc/objc.h> //<objc/Object.h>
#include <stdio.h>

@[EMAIL PROTECTED]
 SmallTest //: Object
- (const char *) description;
@[EMAIL PROTECTED]
 SmallTest
- (const char *) description
{
  return ("I program and therefore I am");
}
@[EMAIL PROTECTED]
 main(int argc, const char *argv[])
{
  SmallTest *obj = [SmallTest new];
  printf ("%s\n", [obj description]);
  return (0);
}
// --------------------------------------------------------
(I had to uncomment the inclusion of <objc/Object.h> because it uses
c++ keywords for message functions etc. The headers comes from the GCC
runtime.)

The code above fails with error:

  Error: declaration syntax error
  main.m line 4   @[EMAIL PROTECTED]
 SmallTest //: Object

  Error: declaration syntax error
  main.m line 6   @[EMAIL PROTECTED]
  Error: declaration syntax error
  main.m line 13   @[EMAIL PROTECTED]
  Error: undefined identifier 'SmallTest'
  main.m line 17   SmallTest *obj = [SmallTest new];

  Error: expression syntax error
  main.m line 18   printf ("%s\n", [obj description]);

If I start with

  #pragma objective_c on

the MW compiler reports the warning

  Warning: illegal #pragma
  main.m line 1   #pragma objective_c on

I noticed also another warning reported by mwcc, that's it using the
compiler from the command line:

### mwcc.exe Driver Warning:
#   No file mapping matches 'main.m' (unrecognized file contents or
filename extension);treating as source text
..
..
..

Thus I wonder if I need to activate something like a "file mapping"? Or
is the Objective c feature is disabled on the x86 compiler?
