Getting Started

Environment

Some initial setup is required before being able to build the code. This is platform specific and described here.

Windows

Install the following:

  • Visual Studio 2017 Community Edition.
    • When asked about installation workloads choose Desktop development with C++
    • Under the “Installation details” section verify that the following are checked:
      • Windows 8.1 SDK and UCRT SDK
      • The latest Windows 10 SDK
  • Git.
    • install the latest version and ensure that Git LFS is checked to be included
    • when the install has completed create a directory for storage of the LFS objects, e.g. C:\GitLFSStorage
    • open up Git Bash and run git config --global lfs.storage C:/GitLFSStorage
    • run git lfs install to initialize Git LFS. (Note that if you miss this step you may get errors due to the third party libraries not checking out properly. This can be fixed later by running git lfs fetch and git lfs checkout in the external\src\ThirdParty directory.)
  • CMake >= 3.14
  • MiKTeX. Installation instructions are available here. Once installed:
    • open the MikTeX console from the start menu
    • switch to administrator mode
    • settings -> select “Always install missing packages on-the-fly”
  • NSIS (optional). Used for building packages

Graphviz is required to generate the workflow diagrams in the documentation. Unfortunately CMake can’t find it out of the box and the following steps are required to make this link

  • open regedit
  • add a new key [HKEY_LOCAL_MACHINE\\SOFTWARE\\ATT\\Graphviz]
  • create a new string value named InstallPath within this key and set the value to point to the install directory of Graphviz.

Linux

Red Hat/Cent OS/Fedora

  • Follow the instructions here to enable the EPEL repository for RHEL7
  • Run the following to install the mantid-developer package
# Install copr plugin
yum install yum-plugin-copr

# Enable the mantid repo from copr
yum copr enable mantid/mantid

# Install dependencies
yum install mantid-developer

Ubuntu

Follow the Ubuntu instructions to add the stable release repository and mantid ppa. Download the latest mantid-developer package and install it:

apt install gdebi-core
apt install ~/Downloads/mantid-developer.X.Y.Z.deb

where X.Y.Z should be replaced with the version that was downloaded.

if you wish to setup eclipse for use developing mantid, then instructions can be found here.

OSX

The build environment on OS X is described here Building on OS X.

Docker

On Docker supported systems you may use the mantid-development images to develop Mantid without having to configure your system as a suitable build environment. This will give you an out of the box working build environment, including ParaView/VATES, Python 3 (where available) and ccache.

More details and instructions can be found at the GitHub link above.

Getting the Mantid code

We use Git as our version control system (VCS). The master copies of our repositories are located at GitHub. We have a number of repositories, of which the main one (the one containing all the source code for Mantid itself) is called simply mantid.

If you are not already set up with Git, you can follow these instructions.

There are a number of URLs via which the code can be checked out using various protocols. The easiest way to get the one you want is to select the protocol you want on the right side of the mantid repository page on github and copy the url into your clipboard. The way to clone the repository via ssh on the command line, into a directory called Mantid, is:

git clone git@github.com:mantidproject/mantid.git

Building Mantid

See Building with CMake for information about building Mantid.

Building VATES

See Building VATES for infromation about building VATES.

Archive access

It is very convenient to be able to access the data archive directly. At ISIS, this is automatically done on the Windows machines, however OSX requires some extra setup.

OSX

  • In Finder “command”+k opens a mounting dialogue
  • For Server address enter smb://isisdatar80/inst$/ hit Connect
  • This should prompt you for federal ID clrc…. and password
  • After completing this the drive is now mounted
  • It can be found at /Volumes/inst$

NB the address in step 2 sometimes changes - if it does not work, replace 80 with 55 or 3.
