## Installation of libarchive

Install libarchive by running the following commands:

    ./configure --prefix=/usr --disable-static --without-expat &&
    make

To test the results, issue: LC_ALL=C.UTF-8 make check.

Now, as the `root` user:

    make install

## Command Explanations

`--disable-static`: This switch prevents installation of static versions of the libraries.

`--without-expat`: This switch disables using expat for xar format support. Due to a bug the xar reader will loop infinitely if expat is used. The upstream prefers libxml2 for xar support anyway.

`--without-nettle`: This switch sets OpenSSL for crypto support instead of preferred Nettle if both packages are installed.
