Anyone got any ideas as to how to compile the Microsoft VisualC 6.0 code that Michal Kowalski's simulator is written in under g++?

Lee.

Several years ago, I fooled around with trying to compile it with GCC and miserably failed. It seems to be locked into Micro$oft Visual C.

Its based on Microsoft's MFC wrappers and support classes for the windows API. It will be a huge effort to port it to another compiler.

The free version of Visual C++ 2008 Express doesn't seem to support MFC applications. You'll need a 'pro' version to stand a chance of recompiling this.

Of course. God forbid Micro$oft doesn't make every last nickel they can. How else can the Gates foundation afford to give away billions to the poor and downtrodden of the world.

Rant aside, I don't do Microsoft development of any kind (nor do I want to), so I'm not about to spend any of my company's money on an overpriced compiler produced by a convicted monopolist.

I've been doing a bit more research and this is beginning to look like a bit of an understatement.

I'm new to using C/C++ so was looking for a project to get started with but this looks a bit too far from portable C/C++ code to be much use.

I have however managed to get a suggestion for lib6502 accepted that fixes a portability problem when compilling run6502.c with GCC under Win32, which was encouraging.

Right now though I'm wishing people would comment their code.

Lee.

Hi Lee
thanks for the heads-up about the updated lib6502.

I had some ideas about projects...

A relatively simple project would be to fit Samuel's lib65816 into the same kind of wrapper as run6502 - I've done that, some time ago, but in a very rough and ready way, and I haven't published it. You could if you wished take my code as a starting point, but it might be better not to!

As it happens, there's a bug lurking in lib65816 (or possibly my run65816) which would be good to find and fix:

whereas lib6502 behaves itself:


A more advanced project would be to take lib6502 and put a GUI around it using a cross-platform toolkit like wxwidgets - that would give us a high performance cross-platform GUI for 6502 emulation. (It wouldn't match Michal Kowalski's program until it could be given an assembler, which would be another project.)

Cheers
Ed

Note that I have a patch for run6502 which is needed for BBC emulation of BASIC errors:



Edit: added link target to new location of Kowalski's simulator

There are a few alternatives to wxwidgets, that may be easier to use:

Qt
Gtk+
Cocoa/Cocotron

--- but the easiest solution might be to embed a simple web server in the simulator, and use a web browser to provide the GUI. (Ok, this solution might be "easiest" only for people who know HTTP/HTML/Javascript better than they known any of those GUI libraries

It might be possible to use a65 (the assembler from cc65) instead of writing yet another 6502 assembler; it might even be possible to incorporate cc65 itself with the simulator.
