Install prerequisites: $ sudo apt-get install g++ qtbase5-dev qtcreator build-essential devscripts libxml2-dev alien doxygen graphviz libusb-dev libboost-all-dev Install CMake. Ubuntu 20.04 has 3.16.3* *note: Some repositories come with older versions of cmake. If that is the case, please build/install version cmake 2.8.12 or later http://www.cmake.org/cmake/resources/software.html Recommended version: http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz View readme.txt in cmake tar.gz file for cmake build and install How To Build This Software: $ mdkir build (in the extracted xfstk downloader directory) $ cd build $ export DISTRIBUTION_NAME=ubuntu20.04 $ export BUILD_VERSION=1.8.5 $ git checkout v$BUILD_VERSION $ cmake .. (make sure that this was the cmake directory that was manually built and installed, i.e. /usr/local/bin/cmake ..) $ make For Debian based systems: $ make package Other optional targets are available. Type `make help` (after cmake has been run) for a list. I.e: $ make docs Explanation: 1) Make a directory. I.E: $ mkdir temporary_directory Q: Why do I have to make a directory? A: This is to initiate an "out-of-source" build so no build clutter will be left in the source tree. If you want to clean up the build you can just delete temporary_directory (more information: http://www.cmake.org/Wiki/CMake_FAQ#Out-of-source_build_trees). 2) Change to the directory you just created. I.E: $ cd temporary_directory 3) Execute cmake. It's argument will be the path to the CMakeLists.txt file. $ cmake .. 4) Simply run the make command with optional arguments. 5) Build debian package xfstk-downloader-1.8.5.ubuntu20.04-amd64.deb that you can install using dpkg
