Preparing the mcidas Account

Complete the instructions below to prepare the mcidas account on Unix and Mac OS X workstations.

1. If the workstation does not have a mcidas account, have the system administrator make one. The new account's default permissions should be set to 755 (umask value 0022).

2. Log on to the workstation as mcidas.

3. Modify the PATH of the mcidas account so that it contains the necessary directories when you log on; refer to the table below. The default PATH of the mcidas account may not contain all the required directories or have them in the correct order.

Operating System Modification
All operating systems If you will be building McIDAS-X using the gcc and gfortran compilers, you must also include the directory containing the gcc compilers in the mcidas account's PATH. See below for other changes needed for each operating system.
Enterprise Linux 6.0+ none necessary
macOS none necessary

4. Log out and log on again for the changes to take effect.
