XTide was designed for Unix and X11, not Microsoft Windows. If you want to try to use it under Windows anyway, there's a precompiled binary for the command-line client, and there are also some ports. However, these are all supported by their respective maintainers. Please route support questions accordingly.

It has become popular among app developers to derive works from the ancient final release of XTide version 1 because the C code of XTide 1 is simpler. Cosmetic issues aside, XTide 2 implements a better algorithm for estimating water levels at subordinate stations and correctly handles more of the unusual cases.

These files were published on the National Geophysical Data Center (NGDC) 5-Minute Gridded Global Relief Data CD-ROM (ETOPO5), 1993, and are public domain. They are available from NOAA at http://www.ngdc.noaa.gov/mgg/global/relief/ETOPO5/BOUNDARY/WVS. Related information is available at http://www.ngdc.noaa.gov/mgg/fliers/93mgg01.html. If the files are obtained from NOAA, the filenames must be changed to all lowercase letters to work with XTide.
This package contains extra scripts to do fast and dangerous GCC builds of all XTide-related packages on particular flavors of Linux as well as build scripts for Android, DOS, Windows, and Cygwin.
|Linux/Fedora||XTide RPMs are available in Fedora's "everything" package collection (formerly Fedora Extras) courtesy of Mamoru Tasaka et al.|
|Linux/Debian||Debian packages courtesy of Peter S. Galbraith. These are extremely out-of-date; you are better off to build from source and get the latest data.|
|DOS||DOS binary for the command-line client (2.15.3) built with DJGPP. It is usable in a DOS box under any 32-bit version of Windows and in DOSBox under 64-bit Windows.|
|Windows||Windows binary for the command-line client (2.15) built with Visual Studio Community 2015 with Update 1. It still has to run in a DOS box, but is compatible with Windows 10 64-bit.|
|Android/ARM||Android (ARM) binaries for tide and xttpd (2.15) built with android-ndk-r10e. The targeted device was a Kindle Fire 1st Gen (arch armv7-a, tune cortex-a9, API level 9, hard floating point). They are runnable only on a rooted device and serve mainly as a proof of concept for libxtide on Android.|
