Exactly what I was afraid of... For us, Windows users, it is defined in
tchar.h as _ui64tow (for "wide" compiles), but I'm not sure that function
exists for you as well. We need a way to output unsigned long (or 64 bit
int) to a char buffer. Either find a way to use that internal (standard?)
function through macros / cmake, or perhaps try this implementation (
haven't been tested!!!! ):
std::string Misc::toString(const uint64_t value){
char buf[20];
_snprintf(buf,20,"%lu",value);
return buf;
}

Subject: Re: [CLucene-dev] Error building clucene on OS X Snow Leopard
I'm pretty new to git, so please let me know if there is a better way to do
this... I refreshed my checkout, applied the patch (git apply ~/diff.diff)
and got the following compilation error:
src/shared/CLucene/util/Misc.cpp: In static member function 'static
std::string lucene::util::Misc::toString(uint64_t)':
src/shared/CLucene/util/Misc.cpp:451: error: '_ui64tot' was not declared in
this scope
Looks as though the patch doesn't work because the compiler can't find the
definition of
_ui64tot(value, tbuf, 10);
Where is this function defined?
