Planet Virtual Boy

How do I turn a C file into something to run in a Virtual Boy emulator? I was fiddling around with Notepad making a C file and I downloaded gccvb and VIDE, but I can't find anything that would do this?

So I get gccvb up and running and i try to make a .vb file out of the sample provided, and I get this.


Anyone have any idea what this means and how to fix it?

Some more information would be useful. Which gccVB version are you using? Looks like the very first release? This error means, that a function (aka macro) "OBJ_YSET" is called in the code, which does not exist. As it seems, the macro in the libgccvb library in that release is still named "OBJ_SET_Y", which was later renamed tp "OBJ_YSET" as it is called in the sample code. So just change that line in the source and see if it works then.

BTW, could you attach images to forum posts? Uploading them to our server is important for future reference. If you just link and then someday delete the image from your server, the thread will be impossible to follow. It's also easier than uloading somewhere else. ;)

I don't know what version of gccvb i'm using, as the read-me file that came with it doesn't say. It makes a reference to v810 patches, if that helps. Anyway, I changed what you said and this is what i got.

Huh? Don't know what that means. But you should try a different approach and try to compile my Programming Introductory Demo. It is meant specially for beginners, and is very well commented and verified to compile fine in the second release of gccVB (gccVB CVS 06-20-05), probably the first one will work as well.

Oops, my bad. I typed in "samples" instead of "examples." Now that I did it right, I get back this error:

Something about parse errors sound much better than FATAL! ;)

Yep, that looks much better. Now you only got a typo somewhere around line 117. See if you can find it or post those lines here, lines 116 - 118.

Success! Well, sort of. It compiles OK, but I made 20 characters and it only displays the first 9. I figure it has something to do with it only handling the 9 characters in "HELLO, WORLD!", the c file I modified to make all but 5 letters appear. I want it to read like the alphabet. How can I get all 20 characters to appear?

After a few hours and tons of tinkering, I made this, what i hope to be an intro to an actual game.

Nice! But you don't need to use objects to have text on the screen, that's way to complicated. Create an ASCII conform font set in vide, export to font.h, include font.h in your source ('include "font.h";', as with libgccvb), and either use a BGMap with text created in VIDE (as shown in the attached image), or, much better, use the vbPrint() or vbTextOut() functions, which dynamically alter BGMaps to place Chars from your font set. Both can be found in "misc.h" of libgccvb.
