[rds-devel] Re: Compiling & Loading RDS

[Vladimir Sokolovsky]

Hi Carl,
Yes, this is a known issue in OFED-1.1.
The workaround for this issue:
Execute attached "create_Module.symvers.sh" script.  This will create 
Module.symvers file.
Copy this file to the linux/net/rds directory and then recompile RDS.

Regards,
Vladimir
