How To Install coan on Fedora 34
Introduction
In this tutorial we learn how to install coan on Fedora 34.
What is coan
coan (formerly sunifdef) is a software engineering tool for analyzing pre-processor-based configurations of C or C++ source code. Its principal use is to simplify a body of source code by eliminating any parts that are redundant with respect to a specified configuration. coan is most useful to developers of constantly evolving products with large code bases, where pre-processor conditionals are used to configure the feature sets, APIs or implementations of different releases. In these environments the code base steadily accumulates #ifdef-pollution as transient configuration options become obsolete. coan can largely automate the recurrent task of purging redundant #if-logic from the code.
