Hi, Peter, I think you misread the error message. There is no error about

Thanks for explaining this, Konstantin.

Re: MIDAS versions
Thanks for pointing that out. I wasn't actually aware that there is a release branch and a development branch.

Re: ROOT problem
I looked into how my ROOT based MIDAS analyzer compiles. It is using the flag -std=c++14.

Right. So the problem is mismatch in ROOT compile flags. The old Makefile build used CFLAGS from ROOT to build rmana and rmlogger, cmake uses some kind
of generic CFLAGS, so here we have it. No idea how to fix it.

For using the release branch read the messages in this thread. Most of the time, the develop branch is fine, except when we are developing something
new, and the only way to tell is to watch the git activity on bitbucket or see the release branch announcements I post on the midas forum.

We updated midas/examples/experiment/frontend.cxx to correctly contain

Actually now I see that
a4) poll_event() and interrupt_configure() have "source" as "int[]" instead of "int" (why did this work before?)

Thanks for tracing the problem further down. Now I realized that the CMakeLists.txt for the ROOT analyzer did not contain the usual ROOT flags. I added
that and committed the change, so please try again. Here is the diff:

I'm still trying to upgrade my MIDAS system to midas-2019-09-i. Most frontends work fine with the modifications already discussed.
However, I ran into some trouble with the epics frontend. Even with the modifications it throws a lot of warnings and errors (see attached log file). I
can reduce the errors with -fpermissive, but the following two errors are persistent:

I fixed the compiler errors in epics_ca.cxx, can you try again? (see https://bitbucket.org/tmidas/midas/commits/)
But, I do not see errors with ca_create_channel() and ca_create_subscription().

Hi Konstantin,
I have EPICS Base Release 3.14.8.2 and got your example running with it, though I had to make one change.
For some reason it wouldn't find libca.so, but when I linked the static library libca.a instead, it worked.

Are there good reasons to not compile MIDAS with set(CMAKE_CXX_STANDARD 14)? So far this was an easier "fix" for me than to recompile ROOT with c++11. |
