Thanks Ludo! Works perfectly also here. However for my understanding. Why does MinGW find
open, filesize etc? Is there some header file that "translates" these functions
to be compatible with msvcrt? If not I would have to create one myself to limit the
amount of work I guess.
Is MinGW finding open, filesize ? When building a static library there
is no verification at all if functions really exist.
Enter
size = whatever(file);
and build your static library. You don't get any errors. Only when
linking the final executable it will start looking for 'whatever'.
In C you don't have to prototype functions. The compiler just assumes an
extern int if the function is not defined in the source or an header
file and leaves it up to the linker to sort it out. Or worse, lets your
program crash if the function exists but has a different parameter list
or does not return an int. Welcome to the joys of programming in C ;)
Yes it does find them, the statically libraries are linked into an executable
which works fine. That is why I was surprised. I'm sure MinGW must link to
other libraries as well. The question though is which. Anyway to find out for a
simple example project executable?
