Code Coverage Of Unit Tests Using Qt 5 On macOS

I was inspired while watching a talk by Kevin Ottens about refactoring OpenGL code in Qt to take a look at gcov & lcov. gcov is used to analyze code coverage – which lines of code have actually been executed while running an application. lcov is a tool that can produce HTML reports from the […]

OpenCV is a BSD-licensed library for digital image processing which implements several hundred computer vision algorithms. Unfortunately compiling it on the Mac was not straightforward—requiring Fink or MacPorts—and the one existing Mac framework was out of date and no […]
