altera_lnsim.sv fails in version 10.5a of Questa compiler

[Altera_Forum]

in questa 10.0.c I have no problems, but when I simply change the questa version to 10.5a I get these altera_lnsim.sv errors

Hi, 

Try to compile using “-sv” switch in vlog command. Can you post the code?   Let me know if this has helped resolve the issue you are facing or if you need any further assistance.  Best Regards Vikas Jathar  Intel Customer Support – Engineering (Under Contract to Intel)
