As part of discussions with Stefan during the MIDAS workshop,
an update to supported versions of c++ on different platforms.

 22 Sep 2025, Konstantin Olchanski, Info, switch midas to c++17
|
Following discussions at the MIDAS workshop, we propose to move MIDAS from c++11 to c++17. There is
many new features and we want to start using some of them.

22 Sep 2025, Konstantin Olchanski, Info, removal of ROOT support in mlogger
|
Historically, building MIDAS with ROOT caused us many problems - build failures because of c++ version
mismatch, CFLAGS mismatch; run-time failures because of ROOT library mismatches; etc, etc.

Following discussions at the MIDAS workshop and the proposed removal of support for ROOT, the very obsolete mana.c
analyzer framework has reached the end of the line.

Hi,
at the LEM Experiment at PSI, we still use mana.c and would like to keep it until end of 2026, where we will enter a long shutdown.
There we will switch to the manalyzer. Before that, there is simply no time for the change over. One thing I already noticed is the "lack" of documentation, |

Excellent, good to hear from you! Once we remove ROOT support rmana.o will be gone, only mana.o (no ROOT) will remain. Will this break your builds?

To record discussion with Stefan about long history variable names.
We have several requests to remove the 32-byte limit on history variable names.

Sorry,
I have had now the time to dig deeper in our code and realized that we actually use rmana, i.e. WITH ROOT. If there is an easy way to incorporate the necessary |

there were no objections to removing ROOT support from mlogger.

I added Makefile rules for running MIDAS through the clang-tidy static code
analyzer. (rules for running cppcheck have gone missing, I hope I find them).

Hi,
has anyone tried runnning midas frontend on a Linux running
on a Motorola MVME167 motorola embedded CPU?

|
I would like to know whether all parameters used by the frontend code have to be in the "Experiment/
Run Parameters" section. This section can become big and difficult to maintain, because it is one single
big section of experim.h (EXP_PARAM_DEFINED). I have parameters the various frontends read at the
