Preparing the mcidas Account

Complete the instructions below to prepare the mcidas account.

1. If the workstation does not have a mcidas account, have the system administrator make one with its default permissions set to 755 (umask value 0022). McIDAS-X relies on the ability for users to run scripts. If the workstation is hardened, update the settings to ensure that users can run executable scripts.

2. Log on to the mcidas account.

3. Modify the necessary environment variables in the mcidas account's $HOME/.profile file so that it contains the necessary directories when you log on; refer to the table below. The defaults 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 and the mcidas account's existing PATH does not include the directory containing the gcc compilers you must add it to the PATH. See below for other changes, if any, needed for each operating system.
Enterprise Linux none necessary
export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)

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