Hi there.
Here is a C++ constructor that is said to work on Windows (i.e., the
guy who wrote it says it works on Win), but doesn't work on Mac. Is
there a way to fix it, except by replacing it with a "copy" method?
Cbyte1::Cbyte1 (Cbyte1 &val) {
m_size = val.m_size;
if (m_size == 0) {
m_totalmax = 0;
b = "";
return;
}
}
Hi Timofey,
This isn't really a Cocoa question, so this isn't really the right
list to be asking.
That said, the rules about which constructor (or for that matter
function) gets chosen are very complicated. It may be that there are
implicit conversions going on that mean that the compiler can't decide
which of the constructors to use (for instance, if there happened to
be a conversion method from Cbyte1 to an "int", you might have the
problem you're seeing).
The solution is most likely to add the keyword "explicit" to some of
the constructors, or to remove the conversion method (assuming it
exists).
Kind regards,
Alastair.
