7-Zip an application made by Igor Pavlov ( http://7-zip.org/ )
gives a very high compression ratio.
Mainy users wish it should also be available in Linux.
see http://sourceforge.net/forum/forum.php?thread_id=758481&forum_id=45797
But as Igor is not comfortable with gcc. So it is difficult for him to port.
7-Zip also use many non standard function from MS-VC++
So a better way to port it to Linux will be to first port it Cygwin or MinGW.
I wish there is somebody to port this.
As per Igor Standalone command line version in folder
Project\archiver\bundle\Alone\
will be easy to port
You can get source code at
http://sourceforge.net/projects/sevenzip/
or get help from Igor at his emailid support@7-zip.org

The homepage contains comparison between 7-zip and another windows
compression programs, but it lacks comparison with bzip2...
Is the compression ratio for 7-zip better than bzip2?
Regards.

I made a try at it, once.. but it has lotsa subdirectories and
libraries... without working Makefiles is not-so-easy to figure out how
to compile.
Moreover the source code is written so "Windows-like" (and I know *no*
Windows programming) that I can't understand which part of the code is
Windows-specific and which one just uses Windows names for "normal
things"...
Hint: the author now accepts 20$ registration with email support...
maybe if we get some people pay him to do help in basic 7z "gcc" support
he would do that sooner, something like "look, we have 20 paying users,
but we would like cygwin supoprt soon, pleeeeaseeee" 0=)
(porting is already in his to-do list... at the bottom of it, actually)

OK, I didn't know that .dsp could be translated "easily" to Makefiles (I
can't find any program that does so *and* works, though) but fortunately
Filip knew it and did a "unsupported" patch.
I upgraded that to apply to 7-zip 3.11 clean source (using cygwin in
-mno-cygwin mode, while his patch used mingw) so that a 7za.exe "stand
alone executable" can be created with cygwin's gcc.
As Biju said in an earlier message, this is at least the beginning...
BTW: 7za.exe is much more like zip.exe than gzip.exe, as it is an
archivier, not simply a compressor.
Could be interesting to "extract" a compressor from it, and maybe adapt
tar to use it, too.
PS: strangely enough, the file is much much bigger (almost the double)
and also a little slower (even if using -O3 -march=i686 it is 2x size an
10% slower than the original anyway)
I don't want to believe that VisualC is better than gcc-3.3 =(

Thanks to work done by "Filip Navara" and "Lapo Luchini" now
we have gcc compliable port of the commandline 7-zip is available.
I started a news group & home page at yahoo for further discussion.
You can get patches there.
