Problems Loading Root to MacBook

ROOT
1

ROOT Version: 6.36.06
Platform: MacOS Tahoe 26.2
Compiler: ?

I have been unable to install Root on my MacBook since an OS update last year. With the most recent update, I tried again, unsuccessfully, using Homebrew. This is what happened when I tried to start Root after executing the Homebrew installation commands:

Mac:root jamesbowen$ root -l

Have you tried to install it form sources ?

Based on your implied recommendation, I went to the instructions for Building from Sources. I then went to Required Dependencies to make sure I was prepared. When I executed the following command:

cmake ../root

the following error occurred, which halted the process:

– Looking for GLEW
– Found GLEW: /usr/local/lib/cmake/glew/glew-config.cmake
CMake Error at cmake/modules/SearchInstalledSoftware.cmake:764 (message):

Could this be at least part of my problems? And if so, how does this get corrected?

Have you tired what the error message recommend ie:
cmake -Dbuiltin_glew=ON ../root ?

Dear Couet,

Thank you. I followed your recommendation, and that apparently corrected that problem, as I was then able to complete the cmake ../root step. I then proceeded to the next step, make -j8 . Several minutes of installation and building followed, until the following error came up:

Moments later, after some more building, the process terminated, apparently due to that error:

Do you have any recommendations on how to correct this error? There’s a comment in there about using some command to see the invocation, but I’m not sure exactly how to do that.

Sincerely,

James

It looks like there is some mismatch in the libraries installed on you machine. What is your machine exactly ? a Apple Silicon one ? to be sure you are doing a clen build you can try the following:

cd ~
git clone https://github.com/root-project/root.git root
mkdir build
cd build
cmake -Dbuiltin_glew=ON ../root
make -j8

The Mac environment you have does work fine for me with the last procedure I sent you (installation from source). According to the error messages you get (BTW, your last post has a lot of duplications which makes it difficult to read) it seems your OpenGL environment is problematic. Also I just noticed that your Xcode is 15.5. Can you check if your Mac (in “System Preferences”) proposes you an update of Xcode ?

On my MacOS26 machine I have:

% sw_vers
ProductName:		macOS
ProductVersion:		26.2
BuildVersion:		25C56

%  pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 26.2.0.0.1.1764812424

Oliver,

I apologize for that being difficult to read.

I checked my Xcode, and it looks like I have Version 26.2 as well. That’s what is says when I open Xcode in Applications.

How do I go about fixing my OpenGL environment?

Sincerely,

James

I have installed XCode on my Mac running OS 26.2 and I see:

% ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs 
MacOSX.sdk	MacOSX26.2.sdk	MacOSX26.sdk

What do you have in that folder ?

What do you get when you type:

pkgutil --pkg-info=com.apple.pkg.CLTools_Executables

Oliver,

I am sorry for my delayed reply. A new semester started since my last message, so I have been busy with teaching. For the list command you gave me above, I have the same thing as you do:

Jamess-MacBook-Pro:build jamesbowen$ ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
MacOSX.sdk	MacOSX26.2.sdk	MacOSX26.sdk

For the second command, this is what I got:

Jamess-MacBook-Pro:build jamesbowen$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
No receipt for ‘com.apple.pkg.CLTools_Executables’ found at ‘/’.

However, I got the same response on another, older Mac that I have where Root still works fine. So I am not sure how significant this is. What do you think?

Sincerely,

James

Dear James,

The second output you get is very suspicious. You should get something like:

couet@macphsft36 roottest % pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 26.2.0.0.1.1764812424
volume: /
location: /
install-time: 1767623608

This command is used to check if the Command Line Tools (CLT) are installed on your Mac and to see which version is currently installed. The output you get suggests that the CLT are not properly installed on your machine. Can you try:

xcode-select --install

Hi Olivier and James,

I have been having the same issue as James. When upgrading from 6.36.02 to 6.38 via Homebrew and updating Xcode via the App Store (also am on 26.2), I see identical errors and outputs from the previous commands in this thread. Upon running:

xcode-select --install

I see the following:

xcode-select: note: Command line tools are already installed. Use "Software Update" in System Settings or the softwareupdate command line interface to install updates

Removing the tools and reinstalling had no effect:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Doing the following resulted in being able to locate with pkgutil:

sudo xcode-select -s /Library/Developer/CommandLineTools

However, reinstalling ROOT after this still does not work, yielding the same original error. Running brew config seems to locate the correct tools, so I am unsure what to do.

What do you make of this?

14

May be this recipe:

# remove the current Command Line Tools
sudo rm -r /Library/Developer/CommandLineTools

# Reset xcode-select
xcode-select -r

# Then install. You will be asked to click a button 
xcode-select --install

# Go in the System Settings -> General -> Software Update 
# if there is a new version of the Command Line Tools, update it.

# Install ROOT
git clone https://github.com/root-project/root.git
mkdir root-build
cd root-build
cmake ../root
make -j8
