Introduction +--------------- -External dependencies (all optional): - - OpenSSL, for "https" URLs. - - GNU gettext, for translated messages. +This document describes how to build Wget from source-code on +Unix-like systems. If you want to install a precompiled Wget, this +document is not for you -- refer to the documentation provided by the +distributors instead. If you already have Wget and want to learn how +to use it, refer to Wget's Info documentation or man page which you +should have received with your system.

Configuration +To build Wget, your system must support a Unix-like command-line +development environment, including the text-processing utilities (sh, +grep, awk, sed, etc.) and a functional C compiler. On some GNU/Linux +systems, this means that you will need to install packages such as +`gcc', `glibc-devel' (or `libc6-dev') and `make'. Most systems come +with these packages preinstalled, but it doesn't hurt to check. If +you have successfully compiled other software from source, you +probably have them all. + +In addition to the C development environment, Wget can use a number of +optional libraries to provide additional features, such as translated +messages and support for "https" URLs. The "external" dependencies +include: + + - OpenSSL -- for "https" URLs. + - GNU gettext -- for translated messages. + +To be usable for building Wget, the listed libraries must be installed +with their "development" header files. On GNU/Linux systems this +typically means installing the corredponsing "lib-devel" or +"lib-dev" package along with the package with "lib". + +2. Configuration ---------------- -Before compiling Wget, you need to "configure" it using the provided -`configure' script. Configuration serves two purposes: it enables the -compilation system to inspect certain features of your operating -system for more robust compilation, and it enables you to choose which -features you want the resulting Wget to have. +Before compiling Wget, you need to "configure" it using the +`configure' script provided with the distribution.
