DLLs

SDL Development

Why is the mingw32 DLL 204Kb and the VC5 DLL 205? I tried both with a
program compiled with Dev-C++, and it seems both work. What’s the difference
between the two?–

Different compilers produce different code. Actually the DLL’s in the
release development archives should be the same. No matter, I’m releasing
SDL 1.1.8 today.

See ya!

A compiler’s code generator might optimize the code for speed or size.
Since they are different compilers, they must use different optimization
algorithms.–

But are the two DLLs interchangeable?–

They should be if they have been compiled with the same code. (or more
precisely, if they follow the same interface)–

Yes. They are functionally equivalent.
Just to be on the safe side though, grab the SDL 1.1.8 DLL when it’s
released later today.

I just downloaded the CVS code and it is chock full of errors. First off,
the SDLmain.lib didn’t work… it produced a runtime error saying it
couldn’t execute the instruction @ address blah, blah, blah. Secondly, it
didn’t make full screen under NT (might work under 9x). Thirdly, it messed
up the x,y alignment was off. I am sending screenshots to Sam.

Real software engineers don’t debug programs, they verify correctness.
This process doesn’t necessarily involve execution of anything on a
computer, except perhaps a Correctness Verification Aid package.
