Linux Standard Base Libraries

If you get the following error:

./lmgrd: Command not found.

or

./lmgrd: No such file or directory

it might be because some required libraries are missing. The license manager in COMSOL 5.2a is built with FlexNet 11.13.1.3, which requires LSB (Linux Standard Base) 3.0 or later in order to start. These error messages indicate that the license server is missing these required libraries. To solve this problem, install the package that provides LSB support for your Linux distribution:

•	For Debian and Ubuntu: lsb-core. Installation command: sudo apt-get install lsb-core

•	For Red Hat®: redhat-lsb. Installation command: sudo yum install redhat-lsb

•	For OpenSUSE: lsb. Install using the YaST package manager.

Some modern Linux distribution do not provide lsb-core. The workaround in such a case is to create a symlink by running the following command as root or with sudo: ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3.
