retrieve, build and install libraries for cross-compiling

apt-cross is intended to make it easier to locate, download, install and update your cross-compiling libraries, directly from the Debian archives. By default, apt-cross uses /etc/apt/sources.list to find the current Debian package file for the architecture specified (or dpkg-cross default) and in the suite specified (default is unstable). Alternatively, you can specify a different mirror. Downloaded files can be passed directly to dpkg-cross using the -b or -i commands to apt-cross. Includes a helper script to support the transition to multiarch.

More information about apt-get remove

Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.

apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.

apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
