Re: ROOT problem
I looked into how my ROOT based MIDAS analyzer compiles. It is using the flag -std=c++14.
|
|
13 Jan 2020, Konstantin Olchanski, Forum, cmake complie issues

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.
|

14 Jan 2020, Stefan Ritt, Forum, cmake complie issues

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:
