Like all GNU software, Wget works on the GNU system. However, since it uses GNU Autoconf for building and configuring, and mostly avoids using “special” features of any particular Unix, it should compile (and work) on all common Unix flavors.
Various Wget versions have been compiled and tested under many kinds of Unix systems, including GNU/Linux, Solaris, SunOS 4.x, Mac OS X, OSF (aka Digital Unix or Tru64), Ultrix, *BSD, IRIX, AIX, and others. Some of those systems are no longer in widespread use and may not be able to support recent versions of Wget. If Wget fails to compile on your system, we would like to know about it.
Thanks to kind contributors, this version of Wget compiles and works on 32-bit Microsoft Windows platforms. It has been compiled successfully using MS Visual C++ 6.0, Watcom, Borland C, and GCC compilers. Naturally, it is crippled of some features available on Unix, but it should work as a substitute for people stuck with Windows. Note that Windows-specific portions of Wget are not guaranteed to be supported in the future, although this has been the case in practice for many years now. All questions and problems in Windows usage should be reported to Wget mailing list at [email protected] where the volunteers who maintain the Windows-related features might look at them.
Support for building on MS-DOS via DJGPP has been contributed by Gisle Vanem; a port to VMS is maintained by Steven Schweda, and is available at https://antinode.info/dec/sw/wget.html.
