[Opencxx-users] Can't compile metaclasses on MacOSX with gcc 4

[Claudio L. <c_l...@ho...>]

Hello,

I am not able to compile metaclasses with occ (versions 2.7, 2.8, or CVS) on 
the mac. I was able to create the occ executable, but then when I use it I 
get the following (other errors were fixed following advice from the forum):


occ -m BeforeClass.mc
EXECUTING: g++ g++ -D__opencxx -E -o BeforeClass.occ -x c++ BeforeClass.mc
/usr/include/stdio.h:258: parse error before `"_" "fprintf" "$LDBLStub"'
/usr/include/stdio.h:342: parse error before `"_" "snprintf" "$LDBLStub"'
/usr/include/stdio.h:374: parse error before `"_" "__svfscanf" "$LDBLStub"'
/usr/include/wchar.h:124: parse error before `"_" "fwprintf" "$LDBLStub"'
/usr/include/stdlib.h:181: parse error before `"_" "strtold" "$LDBLStub"'


The errors above point to the following definitions:

/usr/include/sys/cdefs.h:
#define	__STRING(x) #x
#if __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__-0 < 1040
#  define __DARWIN_LDBL_COMPAT(x)   __asm("_" __STRING(x) "$LDBLStub")
#else
#  define __DARWIN_LDBL_COMPAT(x)   __asm("_" __STRING(x) "$LDBL128")
#endif

/usr/include/stdio.h:
int	 fprintf(FILE * __restrict, const char * __restrict, ...)   
__DARWIN_LDBL_COMPAT(fprintf);


Any suggestion on how to work arround/fix this?

Thanks!
Claudio.
