Macros are usually referred to as variables when they hold simple string definitions, like CC = clang. Macros in makefiles may be overridden in the command-line arguments passed to the Make utility. Environment variables are also available as macros. For example, the macro CC is frequently used in makefiles to refer to the location of a C ...
Similarly, a variable CPPFLAGS exists with switches to be passed to the C or C++ preprocessor. Similarly, FFLAGS enables the addition of switches for a Fortran compiler. These variables are most commonly used to specify optimization or debugging switches to a compiler, as for example -g , -O2 or ( GCC -specific) -march=athlon .
Each Makefile.am contains, among other things, useful variable definitions for the compiled software, such as compiler and linker flags, dependencies and their versions, etc. The generated " Makefile.in "s are portable and compliant with the Makefile conventions in the GNU Coding Standards , and may be used by configure scripts to generate a ...
makedepend is invoked with a list of sourcefiles: . makedepend [options] foo.c bar.c ... However, it is more often invoked as a target from a makefile, typically under the depend target, such that make depend will invoke makedepend on all source files in the project.
In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages , the assignment statement (or expression) is a fundamental construct.
The GNU Autotools, also known as the GNU Build System, is a suite of build automation tools designed to support building source code and packaging the resulting binaries. It supports building a codebase for multiple target systems without customizing or modifying the code.
Unfortunately, a growing body of research has detected contaminants and microplastics pretty much everywhere, including our tap water. Now, new research has detected microplastics in yet another ...
A statement might assign an expression to a variable or use the value of a variable to alter the program's control flow – for example: ... # makefile # -----all: ...
