mac os x / gcc 3.3 link problems with 1.13
i am having troubles getting the 1.13 libraries to link using gcc 3.3. i'm using the libraries included in dd_macosx.tar.gz. i get the following errors when i link to libstdc++.
ld: for architecture ppc
ld: multiple definitions of symbol _zdapv.eh
/usr/lib/libstdc++.a(del_opv.o) private external definition of absolute _zdapv.eh (value 0x0)
/dd/lib/macosx//dd_macosx_alloc.a(odallocop.o) definition of _zdapv.eh in section (__text,__eh_frame)
ld: multiple definitions of symbol _zdapvrkst9nothrow_t.eh
/usr/lib/libstdc++.a(del_opvnt.o) private external definition of absolute _zdapvrkst9nothrow_t.eh (value 0x0)
/dd/lib/macosx//dd_macosx_alloc.a(odallocop.o) definition of absolute _zdapvrkst9nothrow_t.eh (value 0x0)
ld: multiple definitions of symbol _zdlpv.eh
/usr/lib/libstdc++.a(del_op.o) private external definition of absolute _zdlpv.eh (value 0x0)
/dd/lib/macosx//dd_macosx_alloc.a(odallocop.o) definition of _zdlpv.eh in section (__text,__eh_frame)
ld: multiple definitions of symbol _zdlpvrkst9nothrow_t.eh
/usr/lib/libstdc++.a(del_opnt.o) private external definition of absolute _zdlpvrkst9nothrow_t.eh (value 0x0)
etc.
any ideas on how to solve this?
you might try leaving out our dd_macosx_odalloc.a library, and instead including definitions for the following functions in your source code:
extern "c"
{
allocdll_export void* odrxalloc(size_t s)
{
return ::malloc( s );
}
allocdll_export void* odrxrealloc(void* p, size_t new_size, size_t /*old_size*/)
{
return ::realloc( p, new_size );
}
allocdll_export void odrxfree(void* p)
{
::free( p );
}
} // extern "c"

ok, that worked.
i'm now getting 3 unresolved externals:
__zn16odsispatialindex12createobjectebjj
__zn9odsishape13koverallspacee
__zn9odsishape8knospacee
these don't seem to be documented anywhere. is there some way i can include these in my code as well?
you need to link in dd_macosx_spatialindex.a.

ok, thanks for your help.
