Hi,

Welcome to the ROOT forum.

What was your cmake command ?

3

cmake … is my command . execution is fine

4

you do not have any options passed to the cmake command ?

5

i followed following commands:

mkdir root

cd root
cmake …
all thing are fine then

make -j4 etc is showing error

6

What exactly did you use as “…”.

7

i used cmake … nd its working good but i have problem about make -j4

The building output explicitly says that you should inspect “AFTERIMAGE-build-*.log” files, which may contain hints about what went wrong.

Actually, ROOT 6.20/02 is quite old.
You may have more luck if you try the latest release.

I have seen this type of error often when updating my git repo and then building again.
I solve it by calling make clean and then make again. Maybe is something else, but worth a try.
