Hi!

Is there a pthread implementation for AmigaOS? As I wrote at another place, I am parallel to the current work on xMame 1.06 for OS 4 I am working on a port on a new Mame implementation based on Mame 1.23 which has a complete new implementation of the OS dependent layer.

This layer uses pthread. Of course I could reimplement the code part in question using IExec functionality, but using pthread would have the advantage of making portability for future Mame Updates higher.

So my question: Is there a pthread implementation for OS 4, and if yes, could someone point me to where to get it from ? (complete with makefile+source preferred, the crosscompiler I use is quite an old one, not sure if it is still compatible with recent stuff, as you know I have been - away for quite a while from the Amiga scene).

Thanks in advance.

Have you look at:

http://os4depot.net/index.php?functio ... library/misc/pthreads.lha

Check also the new Hyperion SDK, maybe a newest version are there

Don't use the one on OS4Depot, use the one in the SDK!

pthreads.library is part of OS4 since V52.
samo97's link points to threads.library that was superseded by pthreads.library and should not be used anymore.

I gather your advice is directed soley at Steffen from a developer standpoint?

Because depending on version of Tunenet and MPlayer used, failure to install threads.library will produce system error message "Can't open threads.library"

Added: Located another thread which also indicated (as of February, 2009) that the transmission bittorrent client also requires threads.library.

Software linked with the old pthreads needs threads.library. Of course it's OK to install this for existing apps - when the code is recompiled with the new SDK it will get linked to the new pthreads which doesn't need it.

The need for threads.library will diminish as software is updated/recompiled.

All that programms should be updated to use pthreads.library.

Sure. I just wanted to be certain that any users of those programs did not mistake your sound advice concerning development to mean that the old threads.library could merely be deleted from their systems.

No, it's not. The old threads.library doesn't work (not sure if it ever did without problems, at least it doesn't with current versions of AmigaOS 4.x) and you may get random crashes. It's even worse if you run old software using threads.library and new software using pthreads.library or libpthread.so at the same time. You should send bug reports to the deveopers of programs which still use threads.library instead, all they have to do is to rebuild the software with a current SDK, changes in the code aren't required.

If i do a search for threads.library in SDK for os4 i see these files needs it.

sdk:Local/C/perl
sdk:Local/C/perl5.8.5
sdk:Local/newlib/lib/libpthread (this uses pthreads.library, sorry)

Can i just delete the threads.library or do i still have to use it ?
Im no coder. Ofcourse if a program asks for i would need it.

Can you elaborate a bit on the underlying problem? How do they trample each other?

AFAIK both use the same pointer in struct Process for their own thread data.

SDK:Local/newlib/lib/libpthread.a and libpthread.so use pthreads.library, not threads.library. If you have versions using the ancient threads.library installed you overwrote the ones included in the SDK.

If you need software which still uses threads.library like perl and there is no replacement using pthreads.library yet you can't delete it.

I suspect you simply searched for threads.library?

'thread' is a substring of 'pthread' libpthread uses pthread

but your right about perl. It really needs an update for anumber of reasons, but I haven't the time just now. Too busy with blender. (which'll be ready in about two weeks TM).

I run OS4.1 & both Transmission & TuneNet refuse to run without the threads.library. I know pthreads lib is the newer version, but Bean's disappeared & Transmission isn't supported all that well. The threads.library is still needed if you use those 2 apps, like me.

By "refuse to run", those 2 apps put up a shell window saying it can't find the threads.library.

Please keep in mind that it was an answer to a developer. Read it as:

Your totally right. I used a search on sdk:Local/newlib/lib/libpthread and it uses pthreads.library. I just missed there was an "p" before threads :) Only this file slipped my fingers.

Oh Tunenet i use often... Undelete threads.library :)
For transmission i use rather ctorrent.

Hi,

I'll look into it this evening.

Cheers,
