We want to know who you are

The MDSplus developers want to know who you are. If you or your site is using MDSplus please fill the following survey. We promise not to share your contact information. Do not assume that other's from your institution have also filled this out, we will combine the results.

MDSplus User Survey.

Building MDSplus

To build and install MDSplus on unix systems, you will need to obtain the MDSplus distribution from github either as a git repository or as a compressed tar file.

To clone the repositiory:

git clone

This will create a directory mdsplus under your current default.

To download the tarball wget

And then untar it (The exact filename will depend on the release version):

tar -xzf MDSplus-mdsplus-alpha_release-6-3-423-5-gca7f90d.tar.gz

To build the software do the following (See special notes below):

# mkdir build
# cd build
# <mdsplus-src-dir>/configure
# make

However this requires having all the needed libraries and packages installed and there are many different options to configure for building MDSplus. When MDSplus is built to generate releases for public distribution a deploy script is used which uses Docker to pull specially configured Docker images from

You can build MDSplus for any of the linux and windows operatings systems without needing to install any special compilers or libraries. If you have the mdsplus source code and Docker installed on your linux system and your account has privileges to run docker then you can build MDSplus using a simple command:

# cd build
# <mdsplus-src-dir>/deploy/ --os=fc25 --branch=<branch> \
--release=<version i.e. 7.99.100>

The above command will build the installer packages using the sources in <mdsplus-src-dir>/... for the operating system selected. The packages will be named based on the branch and version specified. Note the branch option is only used for naming the packages. It does not checkout or create a git branch. There are many more options to the script which you can see by typing:

# <mdsplus-src-dir>/deploy/build --help

You can find the available operating systems that you could specify for the --os= by doing a directory as follows:

# ls <mdsplus-src-dir>/deploy/os/*.opts

Special Notes

For D3D sites that want to build the MDSplus/d3d ptdata interface you must first define an envionment variable D3DLIB_PATH set to the directory containing the d3 access library, libd3. Then invoke configure as follows:

./configure --enable-d3d

You can build the Motif applications using the static libraries so that the binaries can be used on systems where Motif is not installed. To enable the use of static Motif libraries use the --enable-staticmotif flag:

./configure --enable-staticmotif

Certain optional packages installed on system may be incompatible with some or all of the MDSplus package. We will try to keep a list of potential problems found in this document along with possible workarounds.

F77 compiler problems:

If configure cannot locate an appropriate F77 compiler it will abort. If you have an F77 compiler then define the environment variable F77 to the binary for the compiler. If you don't have an F77 compiler, define environment variable NOF77 to yes and it will allow the configure to continue. You can build most of MDSplus without an f77 compiler.

LessTif conflicts:

  1. If the LessTif package is installed then configure will find it before it finds the real Motif package. LessTif is a marginal implementation of Motif and the MDSplus X applications will not build or run using LessTif package.

To build on a system with LessTif installed do the following:

setenv LD_LIBRARY_PATH [motif-lib-directory]:$LD_LIBRARY_PATH setenv UILPATH [motif-bin-directory-where-uil-image-is] ./configure --x-libraries=[motif-library-directory]

replacing the text inside the brackets (and the brackets) with the location of the real Motif files.

SYBASE Open/CLient - IDL database connection Sites with IDL, SYBASE Open/CLient libraries and Microsoft SQLSERVER databases can use idlsql library for database connectivity. The idl procedure in idl/Logbook/ should be edited to reflect the site specific database connectivity and security policies. The default version assumes that the environment variable SYBASE_HOST contains the name of the host from the sybase interfaces file. It looks for a file $HOME/xxx.sybase_login, where xxx is the name of the sybase host, if it finds it and can read it, it sends the first line as the username and the second for the password, if not it sends $USER and a default password. NOTE - the environment variable SYBASE must point at the sybase distribution in order for their libraries to function. NOTE - if the sybase distribution is not /usr/local/sybase, configure will not find the distribution unless you first set the environment variable SYBASE to point the the distribution directory.
