This software feature allows polymorphic dispatch of function calls based on the runtime type of two objects, improving code reusability and flexibility in C programming.
Doublecpp project is a free preprocessor designed for C, that has an innovative linguistic construct for defining branches of a multi-method. The preprocessor allows the selection of the "right" branch for a method dynamically during run-time, based on the type of the object and the first argument's type, through double dispatch. The GNU General Public License covers the usage, distribution, and modification of this software.
The installation process for Doublecpp is standard and uses a generic set of instructions. The configure shell script attempts to deduce values for multiple system-dependent variables, which are used during the compilation process. These values are utilized to make a Makefile in each package directory, as well as produce one or more .h files that contain system-dependent definitions. Additionally, a configuration shell script called config.status is created so the current configuration can be reproduced later.
There are a few more files that are created during this process, including a config.cache file that saves test results to help speed up future reconfiguration and a config.log file that contains compiler output. If necessary, you can add unusual configurations to compile the package, but consider how to modify the configure script to perform this check correctly.
If there are results in the config.cache file that you no longer want to keep, you can remove or edit the file. The file configure.in produces configure and is utilized by autoconf. You only require configure.in if you plan to alter it or regenerate configure using a newer version of autoconf.
The most straightforward approach to compiling the package is as follows:
1. First, change to the directory containing the package source files, then use ./configure to configure the package for your system. If, on an old System V version, you're using csh, you might have to enter sh ./configure to ensure that csh doesn't try to execute configure itself. The configurer will take some time to run and produce messages indicating which features it examines during its operation.
2. To compile the package, type make.
3. To install programs, data files, and documentation, type make install.
4. If necessary, you can remove binary programs and object files from the source code directory by typing make clean.
