C functions before mainCRTStartup on Mingw?

问题

void start() {
stuff(); //code before mainCRTStartup
mainCRTStartup();
}
int main()
{
//other code
}

In Visual C++,it compiles fine and function "stuff()" gets called before main. How would call "stuff()" before "mainCRTStartup()"? on Mingw(OS:Windows NT)? it seems to ignore "void start()".

回答1:

You could use the -e argument to ld (the linker) to specify start as your entry point.

I'm not sure how to feed arguments to ld using mingw; perhaps someone can edit my answer to provide that.

回答2:

The real entry point is always start().

start() calls mainCRTStartup() that initializes CRT functions and call main(), so in stuff(), you can not use CRT functions.
