When developing cross-platform applications in C or C++, it's common to rely on system-specific headers that might not be available on all platforms. Some headers are present only on UNIX-like...

When building cross-platform software in C or C++, you often depend on system-provided functions or libraries whose availability can vary between operating systems, library versions, or toolchains. For example, certain...
The mold is a linker for Unix systems, designed as a fast, drop-in replacement for tools like GNU ld and LLVM lld. By optimizing parallelism and memory usage, it delivers...
In software development, maintaining a large codebase often involves updating APIs, replacing old functions, or removing unsafe code. However, simply deleting old code can break existing programs that still rely...
In C++, the main function is always the official entry point of a program. However, sometimes we want to execute certain code before main starts. For example, we may need...
Compiling large applications can take a lot of time, especially during development when small changes often trigger rebuilds. Sccache, a modern caching tool and an alternative to Ccache, helps mitigate...
When working with CMake-based projects, one important aspect to control is the build configuration. CMake supports multiple build types that influence compiler options, optimizations, and whether debug information is generated...
When building projects with CMake, the compiled executables often contain debug symbols and other metadata. While these are useful during development, they increase the size of the final binary. For...
Warnings in build systems are often useful: they alert you to deprecated features, suspicious patterns, or potential future breakage. But not every warning is something you can address - especially...
Warnings in build systems are often ignored because they don't break the build. But ignoring them can lead to hidden problems and future breakage - especially when CMake deprecates features...
