I'm trying to port mplayer, I have magicly managed to compile most modules, the problem is when I start compiling the mplayer.c source, currenlty I need to replace this functions whit some thing Amiga native..

undefined reference to `pipe',`select',`swab',`usleep','fork',`waitpid',`glob',`globfree'

I can't help you, i'm not a programmer, but your effort is very much appreciated! I really hope that someone helps yo, so you can manage to port this good software to OS4.
Thank you.

Have you tried starting from the MorphOS source (I'm assuming you've get the generic/Linux sourcecode)? I'd have thought that that'd have more Amiga-friendly calls? Good luck with the port

out of interest of porting things from linux I where thinking about trying to port some thing that some one else have successfully ported before me, I call it an exercise. you may call me nuts

Follow ALX's suggestion. Fork is tricky to fix.

@NutsAboutAmiga

hi m8 i did have a good look at mplayer.c & but if you are trying to port mplayer to a68k you need to do some/litle changes

use> gcc / GNU compiler

write a empty window opens on amiga displays nothing just empty
than go back to mplayer & set intuition/gfx rastar window/screen to mplayers
display not sure what was it called.

first port disable the sound you can add AHI later & will make porting easyer.

goodluck

@NutsAboutAmiga

Unfortunately I'm not a coder so can't help

Are you attempting to port it to 68k or OS4?

Yes I'm trying to recompile for OS40, so I use GCC so this is not a problem,

I don't think I need to change that it supports SDL and SDL exists for AmigaOS,

Just cutting the mixer out will remove 50% of all my problems, what is left is a few fork()'s, select()'s and some waitpid()'s,

From my view it look like it triggers a fork whit inn the modules them self, so that program can skip waiting for sub function to finish.

I don't understand. MorphOS port supports overlay, AHI, everything, no need to invent wheel twice. It can be tweaked OS4'ish later on (use P96 features etc).

@itix
Recompiling the MOS version will be to easy, I'm not doing the port just to get an player on AmigaOS40

@NutsAboutAmiga

Well, at least you could have a look at the MOS sources, just to see how they worked around fork() ans similar

Ciao, Alfred

@NutsAboutAmiga

I aggree with itix, I would try to port the MOS version. It's already tested and it's known to work well. I don't think it's bad if porting is "too easy"

@Serpi

I think i saw one solution in the Amiga Developer help site, it was implemented using ix_vfork() in the ixemul.library. If I remember right MOS has ixemul.library. But it was said that there isn't ixemul.library for the OS4. I don't know, but it's possible that MOS version use that ix_vfork() solution.

@miksuh

Yep. Here is Louise's fork() replacement from the Amiga Developer help site:

#ifdef AMIGA
child_pid = ix_vfork();
#else
child_pid = fork ();
#endif
if (child_pid < 0)
{
// ERROR WITH fork()!
return -1;
}
if (child_pid == 0)
{
// CHILD code;
#ifdef AMIGA
ix_vfork_resume();
#endif
exit (1);
}

@miksuh

fork() - isnt this the unix/linux/BSD equivalent of starting a new Process / Task ?

I would be very interested in 'ahem' testing your work !

@NutsAboutAmiga

just got my AmigaOne & installed OS4 & the SDK.... just wondering what to do next..... (i'm a professional Windoze developer)

can i ask: do u use an IDE, or just a TXT editor? -- i was wondering whether to buy GoldEd Studio, or just do it all manually ...

ps: i would be more than happy to help, if you need a hand... it would be a good starting point.

@Agafaster

My work ? Did you mean NutsAboutAmiga ? We seem to have same avatar

Nothing to test from me until i get OS4 and AmigaOne Well maybe something for OS3.x.

Don't hesitate and go GoldED - it's a wonderful piece of software, there's nothing comparable to it as far as programming tools are concerned. By the way, I have just placed my order, too.

Trixie

@Trixie

I just bought GoldEd AIX myself the other week and it's already destined to collect dust on the shelf... I don't like it, and I've been forcing myself to use it for the last week.

I just can't get into it. For a start it is FAR to much orientated towards M$ Windows, from the look to the wording conventions et all. Makes me shiver. There are far to many configuration options, I thought setting up Opus Magellan from basic installation was a knightmare, this is 1000x worse.

That said, if you've got a lot more patience than I have I suppose you could get it setup the way you want. Me, I prefer using StormC 4 IDE

Some of these are in clib (pipe) or libnet (select), but fork is going to be a problem.
