Xpdf is a viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) Xpdf runs under the X Window System on UNIX, VMS, and OS/2. The non-X components of the package (pdftops, pdftotext, etc.) also run on Win32 systems and should run on pretty much any system with a decent C++ compiler.

Xpdf is designed to be small and efficient. It does not use the Motif or Xt libraries. It can use standard X fonts.

Xpdf should work on pretty much any system which runs X11 and has Unix-like (POSIX) libraries. You'll need ANSI C++ and C compilers to compile it. If you compile it for a system not listed on the xpdf web page, please let me know. If you can't get it to compile on your system, I'll try to help.
