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 […]
Functions of Variants are Covariant
Today I am happy to present a guest post by Alfredo Correa about covariant visitors for std::variant. Alfredo works at Lawrence Livermore National Laboratory where he uses C++ to develop […]
“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.
Hello CMake!
Since I have mentioned CMake in a handful of past blog posts, it is time to give a short introduction for those that don’t know it yet.
Overload: Build a Variant Visitor on the Fly
Having written about std::variant and std::visit last week, it’s time to string together some modern C++ features to build a naive basic implementation of overload, a proposed C++ feature.
Modern C++ Features – std::variant and std::visit
std::variant is a library addition in C++17 for sum types, and std::visit is one of the ways to process the values in a std::variant.
