RE: Error message of StreamDevice while making it.

["Xin, Susheng via Tech-talk" <tech-talk at aps.anl.gov>]

Hi Mark,

 

Thank you so much for helping! As Dirk mentioned that the error might related to the build of the EPICS base. So I just rebuild the latest epics base v7.0.10 and all the other modules related to Streamdevice. And then I re-compiled the Streamdevice. It went though without error. I will test it on Friday and keep you posted.

Best Regards

 

Susheng

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 Mark From: Tech-talk <tech-talk-bounces@ aps. anl. gov>

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!
