Porting SDL app... Chocolate Doom

[cycloid]

To expand the rather cryptic title i'm trying to use AmiDevCpp to port chocoloate-doom to OS3:68k i'm not expecting any mega performance outside of winUAE but it's a prelude to just doing general Amiga/AROS cross porting work.

Anyway i've manged to get the thing configured and compiled, it's just the linking stage. At first i had undefined references to _atof and _pow. adding lib/libc.a and libs/libc_p.a cured this but now i'm getting undefined references to _ixemulbase. I'm building with the -noixemul options so i presume it's trying to staticly link it.

Any ideas which lib i need?


as an aside i've also noticed that the AmiDevCpp tree has four different versions of clib.a, all dated 1999 but different sizes in

lib/
lib/libb
lib/libb32
lib/libm020
lib/libnix

etc.

anyone got experience statically linking ixemul or am i just getting it wrong?

[cycloid]

Yeah i found what i was looking for in libnix, the ixemulbase thing went away once i'd linked it's maths lib in and rebuilt the entire tree, anyway:



It's a start anyway, next step is to compare notes with the Adoom source to see what's different about the wad/lump parsing, there are endian issues with the wad format that probably have something to do with it


EDIT: a little googling suggests that the PNAMES error might be related to MAXTRANSFER but this is running on UAE, any ideas anyone?

[cycloid]

yeah i suspect that there are endian issues, at the mo it's definately reading in (IIRC) 2921 lumps from doom2.wad, which is correct as verified by XWE but any attempt to printf the names of the lumps prints blank lines. will look into sdl_endian cheers


edit: i'm also lacking an amiga 68k inttypes.h or even a stdint.h in DevCpp. i can probably copy the PPC ones over and chop them up until i just have the types it needs but that seems like a lot of hard work , where do i get them from?

[cycloid]

Built 0.2.0 (sans sound and networking)

still had the local path issue but i just stuck -iwad with a full path in to see what would happen next...

did the doom refresh deamon [..............]

conked out with a cybergraphics screenmode error, which probably falls somewhere between SDL and my emulated hardware.

so basically it's getting as far as actually rendering the title graphic but falling over due to external forces, good progress though and it seems to have taken care of the 0.1.4 lump issue

edit: looks like a standard SDL/CGX issue the error is "Found no sufficiently capable CGX visuals" and is a standard SDL bombout when it cant open a screen. I'm running this on WinUAE so i'll need to check what's defined in that (isnt UAE Picasso96 based? is that a problem) and i need to check if it's a dodgy version of SDL that i'm (statically) linking - IIRC it came with an AmiDevCpp devpak so i've no idea which version it is

I now have a progress page up at my domain

having trouble in places seems that "full screen" mode always gives me just an empty blank screen and the AROS version also gives me an empty blank window in "window" mode
