Sega Genesis Dev Kit (SGDK)

I'm trying to get the latest SGDK to work under Linux. The holdup seems to be related to rescomp, there are some TurboC specific calls (stricmp, etc), which I was able to work through.

I've got that compiled and running, but running rescomp complains about missing appack. What is appack exactly?

It will be really great if you can share the fixes you made to get rescomp to compile on linux, i never realized that stricmp was not standard method

Also appack is the aplib packer and i use it to compress resources. Initially i wanted to provide sources for it but i had some troubles to compile it... I will give more time on that next time.

You can find the library and the source here :

For some weird reason, it's stricmp in some places and strcasecmp in others :/

Ah yeah, already saw that... if that is the only change it will be easy

This patch should allow compiling rescomp in gcc. There might be a better way to detect specifically the gcc compiler instead of just linux in the preprocessor, but this should work.

Thanks for changes and makefile !
I included the changes for the methods (i did my own strupper method using toupper()). For the makefile, as i plan to eventually add some files in future i will try to get a generic one (don't need to add file in makefile each time). Anyway compilation is pretty easy, just compile all C files and link them, done

Awesome! I've managed to compile apLib into appack and include that into the linux build environment, so I'm further along. However, when I try to compile any of the samples, I run into some issues. For instance, the joytest example give me an error:

Code: Select all

src/main.c: In function ‘main’:
src/main.c:16:34: error: ‘TileSet’ has no member named ‘palette’

If I look at the definition of TileSet, this does not seem to have palette as a member.

Code: Select all

typedef struct
{
    u16 compression;
    u16 numTile;
    u32 *tiles;
} TileSet;

Don't worry, it just looks like some of the sample are outdated ! Unbelievable i did not noticed it before. Actually for some reason my "rebuild" command did not worked as expected and so i never saw the problem...

Glad you got aplib to compile ! Though i am using a custom aplib now i am thinking about it. It just remove the header aplib identifier to gain some bytes. I guess it's easy to modify it for that, this modification was done by r57shell i believe.

Ahh, so that's probably why the graphics look corrupted then. Do you have a patch against the aplib I can apply?

Unfortunately i just got the exe file from this topic :
viewtopic.php?t=703&postdays=0&postorder=asc&start=15

I tried to look into the sources file of aplib and it looks like that making some changes in the aPsafe_pack method (the 32 bit or 64 bit version depending the one you use) should do the work. Basically you have to remove all the header useless information but i don't know if that is as easy.
Also there is still some aprt i don't understand, it looks like the base aP_pack(..) method is not in the source (i can't find it at least).
Maybe the best easiest way would be to ask r57shell for modified sources.
I will include them in the next SGDK version to avoid any problem, something you can do is to replace my unpack method in tools_a.s method with the usual aplib 68k unpack code in the meantime.

no more int main(int hard) ? to know if it requires to destroy things.
I'm updating sgdk to play a bit

edit: ok, it's here, just got a warning.

kubilus1 · Post by **kubilus1** » Sun Apr 27, 2014 10:17 pm

I've pulled in those changes to appack and now I can get the samples to work correctly! I've included that as part of the linux dev environment project.

Stef · Post by **Stef** » Mon Apr 28, 2014 10:33 am

Nice news ! Thanks for updating the linux dev environement =)
By the way i should definitely add a link to this Linux version on the SGDK homepage, if you agree

kubilus1 · Post by **kubilus1** » Tue Apr 29, 2014 12:08 am

Yes, that would be great!
