Upgrading root installation to root-6.26.10

[juanangp]

• Upgrading installation from root-6.24.2 to root-6.26.10, minor changes added on cmake flags
• scripts/installation/installGarfield.sh updated to tags/4.0. Also reviewed and removed GARFIELD_HOME which is obsolete now.

[juanangp]

I have tested on Ubuntu 20.04 (WSL) and it is working properly @jgalan perhaps you can test on MAC to check that it is working as well?

Suggested change

	make -j8 install
	make -j$(($(nproc) - 1)) install

I updated the option to use as many threads as cores minus 1.

[juanangp]

While doing that my computer got stuck since it is running out of resources, perhaps we can check nproc and remove some cores?

[jgalan]

without a number it might take all the CPUs

[jgalan]

We might use: cat /proc/cpuinfo | grep processor | wc -l? And take half the number of CPUs?

[lobis]

I updated my suggestion to use all minus 1 cores, I remember on some other project's documentation this is the recommended way, I have never seen half the number of cpu as recommended anywhere but we can also try it if this doesn't work.

[juanangp]

I have 12 cores in my WSL, but I already had issues using 10, so I think the safest is to go to the half of the cores.

[jgalan]

SO, cannot we do ($(nproc)/2)

[jgalan]

So, make -j8 is probably ok, perhaps even make -j4. Better to avoid problems.

I go for it

I will test REST compilation with root binaries (6.22.10) on Ubuntu 22.04 (WSL). I think this should be the recommended installation method for root if it's not already (if it works).

Ubuntu 22.04 (WSL)

I am targeting Ubuntu 20.04 and root 6.26.10. I was not able to find Ubuntu 22.04 (WSL) using command prompt, but I see it is available in Microsoft Store.

For info I got the following error on MacOs

Ok, I just revert the changes on cmake params, it is weird since it is working properly on Linux

[jgalan]

Ok, for me in MacOs, after adding -Dbuiltin_glew=ON to the cmake succeeds. It must be noted that glew-dev libraries were installed on my system.

[jgalan]

Works for me on MacOs Ventura 13.1

[jgalan]

I also checked ./installGarfield.sh and worked properly on MacOs
