It also provides many built-in functions which can be used to eliminate the need for shell-scripting in the makefile rules as well as to manipulate the variables set and used in the makefile. [17] For example, the foreach function can be used to iterate over a list of values, such as the names of files in a given directory. [18]
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.
In the C++ programming language, argument-dependent lookup (ADL), or argument-dependent name lookup, [1] applies to the lookup of an unqualified function name depending on the types of the arguments given to the function call. This behavior is also known as Koenig lookup, as it is often attributed to Andrew Koenig, though he is not its inventor ...
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 working Makefile. [ 2 ] The Free Software Foundation maintains automake as one of the GNU programs, and as part of the GNU build system .
makedepend solves this problem by parsing the code of C source files to generate a list of dependencies (those header files included directly and indirectly). It is able to understand conditional compilation constructs so as to not generate excessive dependencies. It then appends rules expressing the dependencies to the Makefile.
The libraries are aimed at a wide range of C++ users and application domains. They range from general-purpose libraries like the smart pointer library, to operating system abstractions like Boost FileSystem, to libraries primarily aimed at other library developers and advanced C++ users, like the template metaprogramming (MPL) and domain-specific language (DSL) creation (Proto).
The qmake tool helps simplify the build process for development projects across different platforms. It automates the generation of Makefiles so that only a few lines of information are needed to create each Makefile. You can use qmake for any software project, whether it is written with Qt or not.
In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. [32] New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for ...
