Dear all,
I am building allpix2 on my MacBook, compiler is AppleClang 12.0.5.12050022
I got this error about the root compiled version:

CMake Error at CMakeLists.txt:240 (MESSAGE):
ROOT was built with an unsupported C++ version, C++17 is required:
-std=c++11 -m64 -pipe -fsigned-char -fno-common -Qunused-arguments -pthread
-stdlib=libc++
Do you know what it is complaining about?
Thank in advance,
Cheers,
Francesco
Hi all,
I maneged to solve this issue by compiling ROOT with c++17, now I have this other issue when I build allpix2:

Do you know what is causing the crash?
Thanks!

Hi @ffollega
Yes, we do require C++17 for the latest version, and this entails a ROOT version compiled against the same standard - but this you have found out already.
Your second error likely stems from the fact that your compiled ROOT (make) but did not install it (make install) but sourced it from its build directory. This doesn’t work since some paths are only properly populated at install time.
