Problem Building CXX object core [27%]

ROOT
,
1

Hello.

I’m having trouble building Root 6.20.04. I’ve also tried Root 5.34.00, but I have the same error. I already tried downgrading GCC to 9.3, but that didn’t solve the problem. Can anyone give me an insight of what might be going on?

Thanks!

Which gcc version you are trying to use?

ROOT 6.20 is relatively old and may not be tested with gcc13 or even gcc12

I’m using gcc 11.3.0.

5

I see same error with gcc11. But seems to be this problem fixed in 6.20.06.
But I really recommend to use newer versions of ROOT.

6

I tried with root 6.26.06, and I got the same problem, even using gcc 12

How you invoke cmake when configuring gcc11 or gcc12?
I do:

export CXX=g++-11; export CC=gcc-11; cmake ~/git/root
