Some time ago, I compiled and upgraded an old Amiga OS program on Amiga OS 3. Last week, I got it to compile on ArOS, and now I'm trying to get it to compile on MorphOS.

It's a modest little Blackjack game that, except for the colors, on ArOS looks like this: Jack31.png

The colors have since been corrected.

Notice the buttons, now here are two other versions, one MorphOS and the other AmigaOS on MorphOS: Jack31m.jpg

The buttons actually do appear on the AmigaOS version, but not when running under MorphOS.

So... before I start poking around, seeing what is causing those gadgets not to initialize, I thought I'd ask here if there's an obvious reason why those buttons are missing on MorphOS. I'm not expecting an answer here, so I'm just asking in case I am missing the obvious.

As always, any and all clues appreciated.

Hard to say anything without seeing the source and crashlog.

Disregard. After going back and re-checking, my m68k version appears to have broken. Not sure how. I gotta go back and recheck some things. I'll ask my question again later.

OK. Take two.

Here are the sources for anyone who might want to take a look.

I put some printf statements in the code and they show that none of the gadgets are initializing. The same thing for the m68k version under MorphOS, but that version runs fine under AmigaOS 3.

I cant test it here right now but is diamond.font installed?

On my machine? I have no idea. I have whatever fonts are installed on the MorphOS 3.1.

I just tried and it seems to work. No crash no Hit.

It works just fine. The included binary as well as a self compiled.

Hmmm... So maybe something wrong with my MorphOS installation? Does anyone have any ideas on how I might confirm that?

Maybe run snoopium and enable debug options from system settings.

OK, finally understanding Itix's comments about the diamond.font, I checked the Fonts: directory and saw nothing that looked like the corresponding Amiga Fonts: one. So, what am I looking for here? Is the MorphOS layout different? Does it define the Diamond.font differently? Searching Fonts: for it came up "bupkis."

The font on the MorphOS and m68k interpreted version is definitely not the same as the others, so it could be a cascade failure from this. It certainly explains why both are failing on MorphOS

The layout of the fonts directory isn't different - MorphOS simply does not provide the font you are using, so you have to install it first (and likely bundle with your application).

Right, I have the diamond font installed, too.

Anyway you should check properly if the font is available and pop up a requester. At least you must not ignore the missing font and continue rendering your stuff.

This will cause hits and crashing and should never happen. The result of any function returning a pointer must be checked! There is no way around when you want to create proper software.

I assume I can copy the Diamond.font into the Fonts: directory. That's good enough for an "install?"

That said, what about storing it locally? In the program's root directory. Will it find it there, or do I have to do something different to make it find it? I'd rather it be there than in Fonts:. Seems easier, ultimately.

You must also copy diamont directory with its contents to FONTS:.

You can also store font locally to PROGDIR:Fonts. I have never used this but diskfont.library in AROS and MorphOS should support it automagically. In AmigaOS it will not work.

EDanaII,
Quote:

If you want to include it, than you need the file and the drawer. The file contains the font describtion, while the directory contains the available bitmap font sizes.

And you need to check the result after opening the font, as the system may fail to open the font, even when it is included und installed properly.

I used Itix's second tip and now it works fine.

Now to take the time to refine it a little more. :)

Thanks all!
