It depends on used options when creating archive, how big and how many files are in the archive/will be in the archive etc., but in short
a lot of RAM is required ;)

Great!  This is one of the best archive programs for other OSes.  Good to see it on Amiga OS3.x.  I just hope I can run it (exactly how much is "a lot" of RAM - is it practical to do anything with only 16 - 32MBs or RAM installed)?

I did a quick test on WinUAE with 32MB RAM and I was been able to compress and decompress 1,5MB wav file with default p7zip's settings.

I loves me some 7Zip, yes I do.  Nice to see it on OS3, which will, of course, run on my MorphOS machine.  Even better if there is a native MorphOS port (have not looked, yet, just thinking aloud.)

That's true. On PPC system you should use PPC binaries, there is no reasone to use m68k ports of open source programs. There should be PPC port available for your system.

Wow. I tried to unarchive a 35MB file having 121MB of free RAM and it complained that i don't have enough memory. :shocked:

And how big are files inside this archive? Which dictionary size was used to create archive? Does Xad's 7z can unpack the archive?

Dictionary size
    Enter the dictionary size for the compression method. The higher dictionary size means the better compression, but it is slower and needs more memory. Memory usage for LZMA compressing is about 10 times more than dictionary size. Memory usage for LZMA decompressing is close to value of dictionary size. Memory usage for PPMd compressing and decompressing is almost equal to dictionary size.

 It was a random file that i found on google to test the port. I remember that there was just one file of about 38MB and the compression method was PPMD.

 No, i have just checked it. It complains about memory too. So, it's the insane memory requirments of the 7zip to blame, not your port.
