The tool is invoked via its command line interface (CLI), and it reports library information via standard output. Some information, such as version information, is more useful to the programmer. Other information, such as command-line options (flags), is more useful to build tools such as a compiler and a linker.
After navigating a command-line shell to the directory that contains the source code, the following commands are typically executed: [1] ./configure make make install For the Autotools, the configure script logs status and errors to file config.log , and the command ./configure --help outputs command line help information.

A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command lines. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. [1]
Tab ↹[command 1] . . . Tab ↹[command n] Usually a rule has a single target, rather than multiple. A dependency line may be followed by a recipe: a series of TAB indented command lines that define how to generate the target from the components (i.e. source files). If any prerequisite has a more recent timestamp than the target file or the ...
Regarding language version support for C++ and C, since GCC 11.1 the default target is gnu++17, a superset of C++17, and gnu11, a superset of C11, with strict standard support also available. GCC also provides experimental support for C++20 and C++23. [46]
Linux From Scratch is a way to install a working Linux system by building all components of it manually. This is, naturally, a longer process than installing a pre-compiled Linux distribution . According to the Linux From Scratch site, the advantages to this method are a compact, flexible and secure system and a greater understanding of the ...
GNU libiberty is a software library with a collection of subroutines used by various GNU programs. [1] The library is now a decommissioned GNU package. [2]It was originally intended to be a sort of standard cross-platform library, thus enabling it to be linked (using the usual Unix library form) by just passing "-liberty" to the compiler.
