Running CVB with elevated rights (root or sudo) on LINUX


just a quick note about running any CVB application as root or with sudo.

Don’t! CVB is intended to be used as a normal user. Not as root. Neither with sudo.
CVB has several requirements for PATH and several CVB related environment variables.

… But sometimes sudo/root is neccesary.
So here are some solution hints:

  1. sudo: Run sudo with as “sudo -E” this will preserve the environment the sudoing user has.
  2. root: The CVB environment variables are stored in /etc/profile.d/ Make sure that these exist in your root/sudo environment (for example: source /etc/profile.d/cvb_…). Check if anything is missing from PATH, which might be required. Same with LD_LIBRARY_PATH.

Hope this helps.
