[Opencxx-users] Open C++ on MacOS X and AltiVec extensions

[Bing-Chang L. <op...@bc...>]

Hi!

I want to use Open C++ on Mac OS 10.2 (and above). I checked out the 
sandbox-kthulhu line using anonymous CVS and it managed to build the 
occ program. The main 2.6.1 release does not support Mac OS X, so I am 
unable to get that to compile at all.

I have two main problems that I would like some input on:

1. Open C++ doesn't seem to like GCC 3.1's Standard C++ library
2. Enabling AltiVec extensions

====================================================
1. Open C++ doesn't seem to like GCC 3.1's Standard C++ library
====================================================
Trying to occ on the following C++ program:

#include <iostream>
int main(int argc, char *argv[]) {
	return 0;
}

Fails with:

MOP warning: The hash table is full.  Expanded...
/usr/include/gcc/darwin/3.1/g++-v3/bits/stl_alloc.h:392: parse error 
before `= *'
/usr/include/gcc/darwin/3.1/g++-v3/bits/stl_alloc.h:401: parse error

/usr/include/gcc/darwin/3.1/g++-v3/bits/stl_construct.h:145: parse 
error before `} namespace'
10 Error(s).  OpenC++ stops.

Removing the "#include <iostream>" produces an executable.

====================================================
2. Enabling AltiVec extensions
====================================================
Trying "occ -- -faltivec main.cpp" on:

int main(int argc, char *argv[]) {
         __vector signed char ch;
         return 0;
}

Produces

main.cpp:2: parse error before `char ch'
1 Error(s).  OpenC++ stops.

I was under the impression that Open C++ is a front-end. So perhaps all 
that I need to do is to get Open C++ to accept my "__vector" as a 
keyword?


Thanks in advance.
