Learning GNU Make Functions with Arithmetic GNU Make has no built-in arithmetic capability. In this article, I present a collection of GNU Make macros that implement functions for addition, subtraction, multiplication, and division of integers. Functions are also provided for integer comparisons such as “greater than” and “not equal.” These macros are implemented entirely using GNU Make's built-in string manipulation functions. |

Tips and Tricks From the Automatic Dependency Generation Masters Make's dependency syntax is flawed because it incorporates both foo.o must be updated if header.h, system.h or foo.c are changed and foo.o is the result of compiling foo.c. Thus, anything to the right of the : is a prerequisite, but the first prerequisite where there's a rule body (i.e. commands) is special: it's the prerequisite that will be passed to the compiler (or other command) to actually generate the target. |

The Trouble with Hidden Targets Make programs are very good at keeping track of targets, files that need to be built, and the dependencies between targets. But the Make program is only as good as its inputs. If you don't tell Make about a relationship between two files, it wont discover it on its own and it'll make mistakes because it assumes it has perfect knowledge about the files and their relationships. |

Tracing rule execution in GNU Make Who hasn't wondered what exactly Make's log file output means. This article is about Makefile tracing. I cover tracing the execution of Makefile rules. |
