Re: Error message of StreamDevice while making it.

Hi Susheng,

Note that you don't actually need to build streamApp in order to use StreamDevice in your IOCs. It is just an example IOC.  I simply comment out this line in the top-level Makefile.

#DIRS += streamApp

Good Morning,

I got errors while I am install the StreamDevice. Does the asyn verion cause the problem. I am using the asyn R4-46 from github. Thank you!
