Installing and Using netCDF-C Libraries in Windows {#winbin}
==================================================
\brief NetCDF-C Libraries in a Windows Environment may be used under multiple sets of circumstances.
[TOC]
There are several development environments available for programmers who develop on Windows.
* `Microsoft Visual Studio `
* `MSYS/MinGW`
* `Cygwin`
For developers using `Microsoft Visual Studio`, you may download using the Windows build instructions, or you may download the pre-built netCDF-C libraries from this page.
For developers using `MSYS/MinGW` or `Cygwin`, you may build netCDF-C using the Linux/Unix build instructions.
> For complex builds that include netCDF-4 and/or DAP support this may prove tricky, as it is time consuming to collect all of the dependencies. In these cases it may be easier to use the pre-built `netcdf` packages provided by the `MSYS` and `Cygwin` environments.
Users who prefer to build the netCDF-C libraries from source in a Windows environment using Microsoft Visual Studio are referred to \ref netCDF-CMake
# Getting pre-built netCDF-C Libraries for Visual Studio {#msvc-prebuilt}
These libraries have been built using Visual Studio 2017. The downloads are installer packages which contain the netCDF-C libraries and utilities (ncgen, ncgen3, ncdump and nccopy), as well as the associated dependencies.
## Included Dependencies {#msvc-inc-deps}
The included dependencies and versions are as follows:
* `libhdf5`: 1.8.19
* `libcurl`: 7.55.1
* `zlib`: 1.2.8
## Latest Release (netCDF-C 4.7.4) {#msvc-latest-release}
Configuration | 32-bit | 64-bit |
:-------------------|:-------- |:-------|
netCDF 3 | [netCDF4.7.4-NC3-32.exe][r1] | [netCDF4.7.4-NC3-64.exe][r5]
netCDF3+DAP | [netCDF4.7.4-NC3-DAP-32.exe][r2] | [netCDF4.7.4-NC3-DAP-64.exe][r6]
netCDF4 | [netCDF4.7.4-NC4-32.exe][r3] | [netCDF4.7.4-NC4-64.exe][r7]
netCDF4+DAP | [netCDF4.7.4-NC4-DAP-32.exe][r4] | [netCDF4.7.4-NC4-DAP-64.exe][r8]
# Using the netCDF-C Libraries with Visual Studio {#msvc-using}
In order to use the netcdf libraries, you must ensure that the .dll files (along with any dependencies from deps/shared/bin) are on the system path. In order to compile a program using these libraries, you must first link your program against the appropriate 'import' (.lib) libraries.
## Install Hierarchy {#msvc-install-hierarchy}
When installed, the netCDF libraries are placed in the specified locations, along with the netCDF-C utilities and dependencies.

# Notes {#msvc-notes}
*The following points should be considered when using the netCDF-C libraries on Windows.*
1. When building the netCDF-C libraries with netCDF4 support, using the `Debug` libraries may cause extraneous warnings. These warnings are related to cross-dll memory management, and appear to be harmless. You can safely ignore them by using the `Release` libraries. [NCF-220]
