Is there an XAD RAR for AmigaOS3.x ?

http://aminet.net/package/util/arc/xad_rar (this is for AmigaOS4)

I want to be able to list inside of RAR files using Dopus5 by double clicking.

(Amikit is configured to do so but since it's missing RAR for XAD, it gives an error)

There's an old one, but RAR3 won't be accessible with it.

As for the new one (mine), I will say what I say to everybody else who asks: The source is in the archive, you are welcome to try building it for OS3.

I had a go here recently but it fails with linker errors - missing clib functions (I think I had to fix a few other things too, can't remember). I can send you the more-likely-to-work source if you want it?

Do you remember what clib functions specifically?

I could take a look at it if you want. I assume it's just normal C code and no C++?

My mistake, libnix is looking for various lib bases, I can't remember if I tried globalising these (although _SysBase in xad_rar.o is almost certainly that). I think whatever startup code it needs needs to be added manually. There are a few other odd things, but that seems to be the main issue. I have very limited knowledge of libnix and even less of using it with no startup code.

It's a mixture. librarextract is C++, my code is C.

Send me an email if interested and I'll get it over to you.

If you're interested, i also wrote a XAD RAR3 client for MorphOS, along with an unrar.library, based on unrar. It handles multiple archives and passwords.

If you're bored, i can pass you the sources. Will need a couple adjustments (mostly for the library specific code).

@Fab

I'm afraid the best code I wrote was 10 print "hello" 20 goto 10

:(

The link in the very first post of this thread now also contains a 68k build.

@Chris_Y

Many thx for this Chris, it was much needed! :)

@Chris_Y

Wow thanks! It extracts small rar archives and one 60mb one using UnARC now. But I can't unarchive many large rar files. I don't even see what's in them.

Also there's a problem. If UnArc is able to show what's inside a RAR file, I lose huge amount of RAM which doesn't come back even if I close UnArc.

It probably needs at least the amount of free RAM as the archive takes up on disk. It shouldn't need much more than that for listing, but will additionally need the length of the uncompressed file for extracting.

Thanks for that, I've just spotted a huge memory leak which I must have thought was getting cleared up by xadmaster's built-in free functions. It's fixed, but it'll take me a few days to repackage.

Is there no way to make it require less memory? My a4000T only has 128mb and and A1200 256mb. I can't even unarchive many rars of ISO files I have using WinUAE with 1gb ram. Some files are really small like 60Mb and their contents don't show up.

@Ancalimon

Can you point me to one of the small files that doesn't open? It's probably not a memory issue.

1GB should be plenty to just list the contents of an archive.


edit I'm having problems getting XAD to even recognise the client since I recompiled, so this might take longer than expected.

The memory leak fix is now up at the same address (RAR v2.3). It is highly recommended to upgrade.

That's great! thanks a lot. Now I wish I can list and unrar files larger than 60mb having 128mb memory using UnARC. Will it happen? :D

I can simply use the unrar command but being able to unarchive a single file from a rar full of many files easily using UnArc or dopus is cool.

@Ancalimon

Not sure if the library I use supports that; certainly the unrarlib interface needs the entire file to be in RAM. I'd need to examine the base library to see if it can do decompression from disk. I cheat on OS4 by allowing it to use VMEM

@Ancalimon

It looks easy enough to use the abstraction interface to do direct XAD file operations. If I haven't done anything with it in a few months, please remind me

@all

You may have noticed RAR v2.4 is in the AmiKit update

I'm just putting together a v2.5 release which has a couple of minor improvements (will show packed size and datestamp, and maybe permissions but I have no idea if that is working)

My large test archive isn't hitting swap space anymore under OS4, so there is a clear performance gain on that particular file.
