I've checked more or less all the answers to this kind of problem wich seems quite usual when compiling with the new llvm package but I couldn't find any solution.

The function getinputfloat is defined in an header file like so:
int getInputFloat(input_file *inp, const char *skey, float *dest, int mandatory) {
int key = getInputKeyIndex(inp, skey, mandatory);
if(key != KEY_NOT_FOUND) *dest = atof(inp->values[key]);
else return KEY_NOT_FOUND;
return KEY_FOUND;
}
and is called by my program like so:
template<typename number>
void grbyinsertion<number>::get_settings(input_file &my_inp, input_file &sim_inp) {
float tmp;
if(getInputFloat(&my_inp, "bin", &tmp, 0) == KEY_FOUND) _bin = tmp;
getInputInt(&my_inp, "insertions", &_insertions, 0);
getInputFloat(&sim_inp, "T", &tmp, 1);
_T = tmp;
if(getInputFloat(&my_inp, "gr_min", &tmp, 0) == KEY_FOUND) _min = tmp;
if(getInputFloat(&my_inp, "gr_max", &tmp, 0) == KEY_FOUND) _max = tmp;
}
I've actually noticed that the header file where the getinputfloat function is defined is a .c file while most (i thought all of them) of the other files are .cpp, could this be the problem?
My llvm version is the 3.5 and I've upgraded all ports installed (via macports). Thanks.
