Prerequisites

VisIt’s Source Code

For a released version

If you want to build a released version of VisIt, you can download a windows installer that contains all that is necessary from the source code downloads page. Look for the VisIt Windows sources link for the particular version you want.

For the latest development version

If you want to build the latest development version from our repository, you need to obtain source from the visit repo, and the pre-built third party dependencies from the visit-deps repo on GitHub.

Other Software

  1. CMake version 3.8 or greater.
    • Don’t use the CMake included with cygwin if you plan on using the pre-built thirdparty libraries.
  2. Visual Studio 2017 64-bit
    • Needed if you want to use our pre-built thirdparty libraries.
  3. NSIS Optional
    • For creating an installer for VisIt. NSIS 2 is known to work. NSIS 3 hasn’t been tested.
  4. 7zip Optional
    • Used to untar testdata files.
  5. Microsoft MPI. Optional
    • For building VisIt’s parallel engine. Redistributable binaries and SDK’s are needed, so download and install both msmpisdk.msi and msmpisetup.exe.
