McIDAS-XRD 7.8 Software and Instructions

McIDAS-XRD version 7.8 was distributed 25 May 2001, and must be built and installed after McIDAS-X version 7.8 (or later) is installed.

You can obtain the McIDAS-XRD files through this web page using your site's login and password (which was also listed on the cover letter that was enclosed with the May 2001 upgrade package mailed to your site coordinator). If you do not know the login and password, ask your site coordinator. If you have a problem obtaining these files via the web, ask your site coordinator to contact the McIDAS Help Desk by e-mail or by phone at (608) 262-2455.

Complete the following steps to obtain and install the McIDAS-XRD software.

  1. Download the following three files to the ~mcidas directory on your McIDAS-X workstation.
    File name Size Description
    mcxrd7.8.sh 16 KB shell script that does the build/install
    mcxrd7.8.sp 0.8 KB disk space requirements file used by mcxrd7.8.sh
    mcxrd7.8.tar.Z 3103 KB compressed tar file containing the source and data files
  2. Log on to the workstation as mcidas and start an Interix ksh. Run all commands below from the ~mcidas directory.
  3. Build McIDAS-XRD 7.8 using the appropriate command below.

    If you are using the default (vendor) compilers,

    Type: sh ./mcxrd7.8.sh make

    If you are using gcc/f2c compilers,

    Type: sh ./mcxrd7.8.sh -gcc make

    After the build is completed, go to step 4 if a previous version of McIDAS-XRD is installed. Go to step 5 if this is the initial installation of McIDAS-XRD.

  4. Uninstall the previous version of McIDAS-XRD with the command below, replacing version# with the number of the version (e.g., 7.7).
    Type: sh ./mcxrdversion#.sh uninstall
  5. Install McIDAS-XRD 7.8.
    Type: sh ./mcxrd7.8.sh install

Once these steps are completed, you should be able to run any of the commands included in the McIDAS-XRD 7.8 package. If a previous version of McIDAS-XRD was installed, it should be removed after version 7.8 is installed, tested, and working properly. Run the commands below to remove it, replacing version# with the number of the version (e.g., 7.7).

Type: sh ./mcxrdversion#.sh unmake
Type: rm mcxrdversion#.sh
Type: rm mcxrdversion#.sp
Type: rm mcxrdversion#.tar.Z
