Error while building ROOT 6

ROOT

Hi!

I’m trying to build ROOT 6.16.00, but there is a strange error:

[ 91%] Building CXX object graf3d/gl/CMakeFiles/RGL.dir/G__RGL.cxx.o

but I have this file!

vlad@vlad-Lenovo-ideapad-330-15ARR:~/HEP/ROOT_6.16.00$ apt-file search GL/glx.h

mesa-common-dev: /usr/include/GL/glx.h
nvidia-340-dev: /usr/include/nvidia-340/GL/glx.h

What is the problem? How can I fix it?

sudo apt-get install mesa-common-dev

It is already installed. Anyway, I have tried to remove build-directory and rebuild it again in the new one after computer rebooting. And there is the new one problem

Try the newest ROOT release.

Well, Now I am trying to build ROOT v. 6.18.04, and I’m facing with the next one error

Try with: make -j 1

The aforecited output has been gotten already with -j 1:

cmake --build . -- -j 1

Hi,
could you provide this please:

ROOT Version: 6.18/04
Platform:
Compiler:

Too many open files

looks like a problem with limits:

ulimit -a

if you were on Unix

cmake version 3.10.2
Platform: Ubuntu 18.04

Well, I used ulimit -n 50000 and this error has gone. BUT there is the new one

Wile is right you need to rebuild pythia8.

Anyway given the different issues you encountered I `d propose
to build root without pythia8 to clearly separate problems.
Also try with j=1 and j=4

Well, I have built ROOT 6.18.04 without PYTHIA 8.

Thanks you both for help!

The ROOT team provides ready-to-use binary distributions for some systems, including various Ubuntu versions, which you just need to download and unpack (see “Using binaries” therein).
