The Unarchiver is a Mac OS X app, but the underlying unarchiving code can
run on other OSes, too. There is not yet any GUI app for any other OS, but there
are two command-line tools,
lsar, which can be used on Mac OS X,
Windows and Linux.
Mac OS X
Pre-compiled versions for Mac OS X are available on the [Google Code download page][downloadpage], or here:
For older Mac OS X versions, use the legacy version:
The Windows versions are currently cross-compiled with Cocotron on OS X. You find binary versions here:
Ubuntu 12.04 packages
lsar, under the package name "unar".
You can install them from the Software Center, or using the command line:
sudo apt-get install unar
Some other distros also package unar, but since I do not use them, I am not sure how to install them. Debian probably handles it similarly to Ubuntu above, and I think Gentoo also has some way to install it. If anyone wants to supply me with instructions for those, I will add them here.
You can also download the source code and compile the tools by hand. To do this, you will need to find and install the required third-party libraries that the XADMaster library depends on (GNUstep, zlib, libbzip2, OpenSSL, and ICU). How to do that depends on which distribution you are using. On Ubuntu, the following should work:
sudo apt-get install build-essential libgnustep-base-dev libz-dev libbz2-dev libssl-dev libicu-dev cd XADMaster make -f Makefile.linux
