C/C++ Programming with Qt 5.12.6 and Opencv 4.2.0
C/C++ programming with Qt 5.12.6 and OpenCV 4.2.0 Preparation of the computer • Download http://download.qt.io/archive/qt/5.12/5.12.6/qt-opensource-windows- x86-5.12.6.exe and http://www.ensta-bretagne.fr/lebars/Share/OpenCV4.2.0.zip (contains OpenCV with extra modules built for Visual Studio 2015, 2017, 2019, MinGW Qt 5.12.6 x86, MinGW 8 x64), run Qt installer and select Qt\Qt 5.12.6\MinGW 7.3.0 32 bit and Qt\Tools\MinGW 7.3.0 32 bit options and extract OpenCV4.2.0.zip in C:\ (check that the extraction did not create an additional parent folder (we need to get only C:\OpenCV4.2.0\ instead of C:\OpenCV4.2.0\OpenCV4.2.0\), right-click and choose Run as administrator if needed). For Linux or macOS, additional/different steps might be necessary depending on the specific versions (and the provided .pro might need to be tweaked), see https://www.ensta-bretagne.fr/lebars/Share/setup_opencv_Ubuntu.pdf ; corresponding OpenCV sources : https://github.com/opencv/opencv/archive/4.2.0.zip and https://github.com/opencv/opencv_contrib/archive/4.2.0.zip ; Qt Linux 64 bit : https://download.qt.io/archive/qt/5.12/5.12.6/qt-opensource-linux-x64-5.12.6.run (for Ubuntu you can try sudo apt install qtcreator qt5-default build-essential but the version will probably not be the same); Qt macOS : https://download.qt.io/archive/qt/5.12/5.12.6/qt-opensource-mac-x64-5.12.6.dmg . -

A Live Linux Based on KNOPPIX/DEBIAN with Special Emphasis on Scientific Packages Including ROOT Motivation (Students)
● Debian ROOT packages by ROOT team and Chr. H. Christensen ● Collaboration of Helmut Wolters (german), Vinc. Vangoni (Italian), Pedro Ferreia (French), Oscar Diaz Fouces (Spanish) ... PAIPIX: a live linux based on KNOPPIX/DEBIAN with special emphasis on scientific packages including ROOT Motivation (students) ● A live system requiring no installation ● Including latex to be able to undestand the source arXiv scientific papers. ● Including code development environments ● It should also support portuguese State of the art Several live systems available based either on Debian: KNOPPIX...or Gentoo. The major Linux releases like REDHAT or SUSE include a live DVD. While KNOPPIX was by far the best and most used, it did not met our goals Motivation (Supplement) The informatics people at my University discouraged me to do anything.... Choices ● Compressed file system of KNOPPIX seemed the best ● There was information around on how to extend modify the CD images ● It was based on the powerful and free Debian system ● Including only full Latex implied already to go from CD to DVD ● Once we opted for DVD the road was open to include: ●Scientific applications available in Debian ●New scientific applications by creating Debian packages ●Also the SERVER tools like web, database and Content M. Systems ●Nice things to help interesting the students like ... games ● Once installed on disk it becomes normal DEBIAN Scientific Packages Selected from Debian Development/ Prog.
