FLEXlm: Error message on GLIBC_2.0 when starting lmgrd on Linux

22-Apr-2026

On some systems, when starting lmgrd on Linux, it displays the following error message:

relocation error: ./lmgrd: symbol errno, version GLIBC_2.0 not defined in file lib.so.6 with link time reference


Possible solution

Prepend LD_ASSUME_KERNEL=2.4 to the lmgrd startup command.

For example:
LD_ASSUME_KERNEL=2.4 lmgrd -l /var/tmp/lmgrd.log
