Well,
I've tried to work through the solutions to:
ld: common symbols not allowed with MH_DYLIB output format
Which are basically "-fno-common" on the compile line of each file, but apart from the fact that tihs doesn't actually work in this case (we still get the error), it's not really a very good idea.
Does anybody have any suggestions for working around this code:
namespace boost {
namespace io {
namespace detail {
namespace { template<class Tr, class Ch> inline
void empty_buf(BOOST_IO_STD basic_ostringstream<Ch,Tr> & os) {
static const std::basic_string<Ch, Tr> emptyStr;
os.str(emptyStr);
}};};};};
The correct thing to do with this code (for all platforms) is to not rely on the global variable "common" stuff (which is new to me, and seems a bit of a hack), but actually do this code correctly, which means removing the global variable.
What problem is the code above trying to solve?
If i just do this (which i have done to get my stuff working), there seems to be no prob:
#ifdef MACHACK
template<class Tr, class Ch> inline
void empty_buf(BOOST_IO_STD basic_ostringstream<Ch,Tr> & os) {
extern const std::basic_string<Ch, Tr> emptyStr;
os.str(emptyStr);
}
#else
#define empty_buf(_os_) (_os_).str("");
#endifWouldn't the above two lines achieve basically the same thing (although I know we hate macros, but since "empty_buf" is only actually used 3 times in the entire project, could all of the:
empty_buf(oss);
be replaced with:
oss.str("");
This would save a whole lot of grief and eliminate this fairly ugly global variable.
