Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

Conditionally compiling your source code


Conditional compilation is a simple mechanism that enables developers to maintain a single code base, but only consider some parts of the code for compilation to produce different executables, usually in order to run on different platforms, hardware or depend on different libraries or library versions. Common examples include using or ignoring code based on the compiler, platform (x86, x64, ARM, and so on), configuration (debug or release), or any user-defined specific conditions. In this recipe, we take a look at how conditional compilation works.

Getting ready

Conditional compilation is a technique used extensively for many purposes. In this recipe, we will look at several examples and explain how they work. The technique is not in any way limited to these examples. For the scope of this recipe, we will only consider the three major compilers, GCC, Clang, and VC++.

How to do it...

To conditionally compile portions of code, use the #if, #ifdef, and ...
