Some of demos of Xcos can not run.

Modelica translate error messages are:  
Main Modelica : C:\Users\honey\AppData\Local\Temp\SCI\_TMP\_10848\_5881\RLC\_Modelica\_im.mo

“c\_pass1: build the modelica meta-block failed”

“xcos\_simulate: Error during block parameters update.”

Would you help me work it out?

Thanks.
