Re: Help adding Measurement Computing support to IOC

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Hi Jesse,

Sorry, I missed the part of your message that said you had installed libuldaq-1.2.1.

So all you need to do is add these lines to your Makefile.

labjack_SYS_LIBS += uldaq

labjack_SYS_LIBS += usb-1.0

Subject: Help adding Measurement Computing support to IOC

 

Hi folks,

I'm attempting to add support for Measurement Computing devices into an existing IOC (that I currently use with some LabJack devices). However, I'm having an issue with building the IOC.

As far as I can tell, the measurement computing support builds fine (I'm building it as part of synapps, but updated to the latest version of MeasComp in the git as of a couple of days ago). I can run one of the test IOCs that is included with the support in the synapps build without issue (in this case for the E-TC).

The problem comes when I try to add the support to my IOC. I go to rebuild the IOC and I get the following errors:

In case it helps, I'm attempting to build this on Debian 12, and I did install the libuldaq-1.2.1 vendor drivers as instructed.

If anyone has insight into what's going wrong that would be great. The IOC builds fine if I remove the measComp DBD and LIBS in the Makefile, but otherwise gives the above errors.

All the best.
