Unrar & 7zip

[namtih]

Does anyone have the time to compile the latest versions of Unrar and 7zip für the WD?
It doesn't need to be a real app.bin, executables would be enough of course.

1. Unrar
Source: http://www.rarlab.com/rar_add.htm ("Unrar sources")

2. 7zip
Source: http://www.7-zip.org/download.html

I want to try 7zip as an alternative to Unrar, as I've read that it should be a little bit more CPU-friendly.

Edit:

So stay with unrar3, or someone knows how to create an optimized version.

1. http://files.wdlxtv.de/unrar-4.0.0-mips

2. http://files.wdlxtv.de/7z-9.20-mips

I haven't really tested them yet but at least they executed without errors

give me one single reason why unrar should be updated, and no 'its newer' is not a reason.

@recliq
Thank you very much for your quick help! The executables seem to work fine.
I think I will run some speed tests over the weekend and will report the results here.

Short question:
When I execute your unrar-version, it stats "UNRAR 4.00".
The last news is for "4.01" and the unrar source is marked with "4.0.7". Did you use another source? It's not critical, I've only noticed it.

@b-rad
Actually there is no reason. The last test with a beta version some months ago was very disappointing, as the unrar executable had a bigger file size and the unrar performance was slower than the current/old version:

But I'm using the unrar function alot, so I want to give it another try. Perhaps there are some speed improvements now with an updated version or 7zip.

unrar is compiled from unrarsrc-4.0.7.tar.gz

While watching football, I wanted to run the tests.
But 7zip throws an error, when trying to extract an rar-file:

Code: Select all

Error:

As 7zip isn't working, I wasn't able to test it yet.
But I wanted to share the results of the unrar tests, as I would call it a big suprise

Archives:
a1: 1 wmv-file => 421MB
a2: 5 pdf-files => 106MB
a3: 1 wmv-file splitted on 3 archives => 200 + 200 + 122MB
I ran two tests yesterday and one today. Except some seconds the results were the same.

Code: Select all

The default compression level might be higher in newer versions. Or they are now optimizing the code for modern CPUs with more cache than the Sigma SoC has.

ups...
I'll upload and post a link to the missing file as soon as I get home...

EDIT: Here you go... http://files.wdlxtv.de/7z.tgz

Something is still missing, as I get the error message "Unsupported method" when I try to extract a rar file.
It seems a library/plugin is missing:

But I think I will simply stay with the original unrar version, as it seems working fine at all.
Perhaps I will try to learn how to compile those WD apps myself to try some other things, but yeah... we will see. Thanks for your help recliq!
