Thanks for the suggestion. It looks like it is instead the TRIGGER_ALL that is causing the problem. TRIGGER_ALL is defined as -1 in midas.h. If I replace TRIGGER_ALL with 0 in the
frontend, it compiles, but if I use -1, I get the same error. I do not think that I want my trigger mask set to 0. Do you have a suggestion of how to get around this?
To answer the other questions, we are running on SLF6. I am building a frontend for a MWPC to read data from CAEN TDCs. |
