All Things Ubuntu Library

ATU Library (All Things Ubuntu Library) is a collection of libraries in Object Pascal for use with FreePascal and Lazarus IDE, that provide API dedicated to various versions of Ubuntu, including: - standard desktop Ubuntu - Ubuntu Mate ARM (ie. raspberry pi) - Ubuntu Touch/UBports Since most of resources available for Lazarus programmers are related to Windows OS, this library is aiming at addressing those interested in Linux programming with FPC and Lazarus, but tested with Ubuntu distributions. On Ubuntu Touch, you can install everything from the Terminal app or via ssh, either or will work. Just follow these steps: #download: $ wget https://sourceforge.net/projects/all-things-ubuntu-library/files/ATU_arm-linux.tar.gz #extract: $ tar -xf ATU_arm-linux.tar.gz #install ATU locally: $ ./ATU_arm-linux --install #you also recommended to install dependencies like this: $ sudo ./ATU_arm-linux --installdeps #if you're using Vivid this will also f
