[Wii] Having trouble compiling VICE Libretro and how to put the required library files correctly?

[saulfabregwiivc]

Coming from #373

Can please anyone tell me how i can install the required libraries used by this Libretro port of VICE so i can compile it properly?

There are too many libraries used by this port and i just can't figure out how i can put the required libraries files into the correct paths required by the files (e.g. on #include "arch/shared/archdep_access.c" in retrodep/archdep.c, but that file doesn't exist in that exact path but in another path)

Btw, i'm compiling in Windows, but i'm trying to compile a core for the Wii.

Thanks.

I don't understand what you mean. There are no extra libraries, and everything is included in the repo.

I get this error when compiling the resulting dol file:

LookToRead2_CreateVTable is regular 7zip stuff which is under deps/7zip/, but Wii uses static linking, which means it isn't using those files. Makefile does have NO_7ZIP flag, so you should be able to at least test it without 7zip support.

Regarding that access function you might want to copy the one defined for #ifdef __PS3__, since it seems common and simple enough:

int access(const char *fpath, int mode)
{
    struct stat buffer;   
    return libretro_stat(fpath, &buffer);
}

Then again buildbot is able to build it without that, so something missing in your toolchain then I guess.

So i can temporally disable static linking by passing the argument STATIC_LINKING=0 when compiling VICE for Wii, right?

Anyways, i've disabled 7-Zip support here and added the int access as you suggested, but keeping the static linking.
Everything still compiles fine the libretro_wii.a file, now i will see if it now compiles the dol file.

Thanks, i will post more results later.

No, I don't think you can just disable static linking and expect it to work. It needs RetroArch built-in to be usable. Check the gitlab recipes to see how the template works.
