p7zip is a port of 7za.exe for POSIX systems like Unix (Linux, Solaris, OpenBSD, FreeBSD, Cygwin, ...), MacOS X and BeOS.
7za.exe is the command line version of 7-zip.
7-Zip is a file archiver with highest compression ratio.
Since 4.10, p7zip (like 7-zip) supports little-endian and big-endian machines.
INSTALL:
method 1
- edit install.sh to change DEST_HOME
- ./install.sh : to install
Remark : you must be "root" to install 7za in the directory "/usr/local"
method 2
- 7za is a stand-alone program, you can put this program where you want. example : cp bin/7za /usr/local/bin/7za
- 7z needs its plugins. You must copy the file 7z and the two directories Formats and Codecs in the same destination directory.
- if you want to be able to create SFX archive, copy bin/7zCon.sfx to the directory where 7za or 7z can be found.

- Fixed : makefile.linux_amd64_asm_icc
- DJGPP : makefile.djgpp becomes makefile.djgpp_old / makefile.djgpp_watt added (thank to Rugxulo)
- you can now compile 7za with a cmake project (see README) the cmake project can build a codeblock project
- Remark : the kdevelop3 or Eclipse/CDT4 project don't work
