Not pertinent to this, but the main reason people miss symbols is failing to include proto files.

That's not the case anymore. Since OS4 doesn't really use C function stubs for calling library functions anymore, but interfaces (which are a collection of function pointers), failing to include a proto file will get you messages like "IExec not defined" or "Undefined symbol IExec" during link.

Thing will be easier when Ixemul.library is released I think.

Why that ? It will make porting pure Linux software easier, but most SDL applications are writtne with portability in mind and should work "out-of-the-box" (I know that's nostly impossible).

For example, SDL_sound and the OpenGL libraries do not exist yet for Os4.

Most of these SDL addons compile out of the box... You need to configure them, though, which is of course a problem

It is possible. But is the cross-compiler kit released to public yet?

No. It's packed up ready for release, but some documentation is still missing.

My brother and me had a rather difficult time recently, which means a lot of stuff wasn't handled yet. We're working on it.

@EntilZha

Anyone looked at the auto* tools to see how hard/easy they would be to build for AmigaOS or are they far too Unixey?

@EntilZha

I didn't mean that everyone should use -ixemul, but having ixemul.library should make GeekGadgets available, to fill the gaps in the native SDK (if there are some anymore :)

There has been some effort in the AmigaOpenOffice team. I don't know how far they progressed with this, though...

Basically, it's a big bunch of perl scripts, generating shell scripts. Since perl is no available OS4 native from OS4depot, and abc-shell is coming along, it might be possible...

Sure, I got that ... I was just asking why in the context of SDL programs.

The author of Mupen64 (N64 emulator) recently released
the source for Mupen64 and related plugins, saying that its
an easy SDL port...if any talented coders out there would
like to have a go...
I hope you and the OS4 team remember that sleep and
recreation are turnkeys to success and productivity.
Will Hyperion be @ e3 next year? 8') Hope so!!!

@glokraw

N64 emulator without hardware 3D acceleration will be slow even on 1 GHz AmigaOnes.

sdlTTF is ported, by the guy who ported super mario clone.
i think he ported quite some SDL stuff, hmm, he should make them available somewhere.

Yes, I have it. Received it by e-mail today, and already ported some code.

Cool! Why not make useful stuff like that available on the depot?

Because they still have bugs and I don't have the feeling I should release buggy, untested and crashy software on OS4Depot.
Usually after some test period I release stuff to the public and save the blames this way.

P.S. Thanks Juha.

If the configure script aborted due to an sdltest program being run (which doesn't work on cross compilation of course) edit it out of the configure script (yes, I know this is a crude way of doing things ) and configuring again.

This is not always necessary. Often configure scripts have an option to ignore sdl test and/or force SDL compilation.

I.e. hatari has an option --disable-sdltest, so "configure --disable-sdltest" could give correct result in a crosscompiler environment. Supported options may differ of course.

Hmmm, if that line you posted is complete, then obviously there is a -lSDL missing.

I thought I had added that to the command line, but I don't remember, it's been 4 days and I lost the sources soon after. :-/

Anyway, I didn't want to leave SpotUp hanging dry, so I just gave it another shot.
This time I got it going the first time

I'll post the port to OSDepot, it's quick and dirty (e.g. I only changed the Makefile and dropped any reference to /shared/cgterm/ in the .c files), but it seems to be working.
At least I was able to connect to the POP daemon of a remote server.

edit: CGTerm/Chat can be downloaded now from OS4Depot

True, some have them, but in my experience most programs do not have this option.

And there are other libraries which are tested using executables (existance of specific symbols in zlib and libtiff is sometimes done that way, and disabled if "not found" - sometimes a "force" option exists but in my experience only in very few projects).

@AmigAlex

Oh! So I noticed! Thanx a million! Cool program isn't it? =)
You really should try to connect to a C64 bbs, you will be amazed when you see the nice petski, and the activity in the C64 scene, sorry can't give out the url to the one I call as it is kind of illegal. :/

I will have a go at another SDL app when I have studied all your tips a bit closer, I think I will have a go at DosBox, I heard it was a quite easy one. :)

Yes, I did try it (see screenshots on os4depot) it reminds me of the good old days, the simplicity of BBSes was nice and made it easier to stay focused on one task and to connect with other people. I guess having IRC and Amiga forums isn't all that different.

Looks like the BBS scene is still alive though, and it's neat that some people are using real C64s to serve the pages. And at least one of them must be running on an Amiga because it said "opening telnetd.device"
BTW there's a list at http://thebbs.org and more can be found on Google.

As far as porting SDL apps, don't do what I did, that was a bad example

I just wanted to get it done before I forgot about it again, but normally you'd want to leave the original code intact and insert #ifdef __amigaos4__ (or something like that) where needed so that the changes can be sent back to the authors and the Amiga hopefully added to their list of supported OSes.

Alternatively, you can use a config.cache (-C option) and add the untested option into the cache.
