Hi,
unfortunately I don't have a documentation link to the feature, I just know that it works on my machine ;-) The general idea is that you place a custom |

Dear all,
Stefan wants to run an external EPICS driver process as a detached process and somehow "glue" it to midas to control it. Actually a
similar requirement led to the development of MIDAS in the '90s. We had too many configuration files lying around, to many process to control and interact |

In the DEAP experiment, the normal MIDAS mlogger gzip compression is not fast enough for some data
taking modes, so I am doing tests of other compression programs. Here is the results.

I redid the tests from Konstantin for our MEG experiment at PSI. The event structure is different, so it
is interesting how the two different experiments compare. We have an event size of 2.4 MB and a trigger
rate of ~10 Hz, so we produce a raw data rate of 24 MB/sec. A typical run contains 2000 events, so has a

I tried to solve the problem by adding a ";". It was wrong. In fact, the macro "_syscall0(..)" doesn't need the ";".
I searched and found that somebody said "the overall _syscall$magicnumber will disappear". I don't mind whether the "_syscall" disappear or not. I just
want to compile the code and do my job. I deleted the additional ";" and recompiled. The error output is as the attachment [elog:335/1]. |

FWIW, I do not have macos 10.15. I have 10.13 at home and 10.14 in the office. Maybe Stefan has it?

Best I can tell, the problem is not in midas: pthread.h should be there, somewhere.

For your reference, here on my MacOSX 10.14.6 with XCode 11.3.1 the pthread.h file is present in locations listed below.
Did you execute "xcode-select --install" ?

Another thought: Can you delete the build directory and run cmake again? Like
