I would think that one reason something like this doesn't exist is because it really just isn't plausible. Unlike Perl or Java, C/C++ implementations vary from machine to machine and compiler to compiler. By that, I mean that an int on one machine with one compiler might be stored as 4 bytes while on another machine with a different compiler might be stored as 8 bytes. Obviously, there are other, possibly more severe issues than this - this is just a quick example. Using someone else's code written with someone else's compiler is almost guaranteed to give you problems. The only real solution would be to rewrite every class for every system/compiler combination available. <Extreme Sarcasm>Good luck!</Extreme Sarcasm>
in reply to Interesting article on CPAN and C/C++
This is a limitation of C/C++ but, due to this limitation, C/C++ is able to provide incredible execution speed over languages such as Perl and Java which are not compiled to the degree that C/C++ is.
Appealing as the thought of a CCAN might be, I (coming from a fairly strong C/C++ background) sure wouldn't know how to write a class that anyone could use.
Skepticism is the source of knowledge as much as knowledge is the source of skepticism.
