Same, same, but different: when different values compare equal

Modern C++ Features – Quality-of-Life Features
With the new C++ standards, we got a lot of features that feel like “quality-of-life” features. They make things easier for the programmer but do not add functionality that wasn’t […]
“Modern C++” != “New(est) Standard”
The term “Modern C++” is often used interchangeably with “Code using the new C++ standard”. Here, “new” may be anything from C++11 to C++17 or even whatever is available of […]
CMake – Properties and Options
Today I’ll continue the little CMake tutorial series. We’ll add a few options and a bit of fine-tuning to the compilation of our example project.
Reproducible build: environments and scripts
Have you ever seen one of those nasty errors that appear on one machine and not on another? To be able to track those down we need a reproducible build […]
“Builds on my machine!” – About local build
In the last week, I had several occurrences that again taught me something I already knew – at least in theory. Local build results can be deceiving.
CMake Project Structure
As promised in the last post about CMake, today we’ll use a proper CMake project structure for our “Hello CMake” project.
Modern C++ Features – std::optional
Sometimes we want to express the state of “nothing meaningful” instead of a value. This is the use case for C++17’s std::optional.
CMake – Another Target and the Project
Last week, we’ve started our little CMake project with a “Hello CMake” one-liner. Now it’s time to expand that example by adding another target and information about the project.
