Root_v6.24.06 in macOS Monterey

General Chat
1

Hello, I have updated today the macos of my laptop to macOS Monterey (12.2.1) and then my root installed version stopped working and it was complaining that: /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk was missing. For whatever reason, I did figured out that I need the Xcode 12 for Monterey, so I downloaded root_v6.24.06 (from Release 62406 - ROOT)
curl -LO https://root.cern/download/root_v6.24.06.macos-11.5-x86_64-clang120.tar.gz
and install it. In parallel I did dowloaded also Xcode 12 and now MacOSX.sdk points to MacOSX12.0.sdk which does indeed exist.

However root still not running and the error message I’ve go now is given below.

My question is: is there a recipe to fix this problem?

Thanks for your help

Hi,

You have installed a version for macOS 11 and instead you have 12.
You can try to install the 6.26 candidate release version from our nightly builds. We have
a binary for Mac with arm chip (M1 or M1 Pro/Max):
https://root.cern/download/nightly/root_v6.26.99.macos-12.2-arm64-clang130.tar.gz
or a binary for the Intel chip:
https://root.cern/download/nightly/root_v6.26.99.macos-12.2-x86_64-clang130.tar.gz

These should work on Monterey

Cheers

Lorenzo

I installed this binary just now on a mac with 12.2.1:

https://root.cern/download/nightly/root_v6.26.99.macos-12.2-x86_64-clang130.tar.gz

and see the original problem reported:

root

I can see the requested file:

ls /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/net.modulemap
ls: /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/net.modulemap: No such file or directory

does not exist, though the directory where it should be does exist.

What have I got wrong here?

Cheers,

Turns out somehow when upgrading mac os and Xcode the new sdk was not installed. Removing the command line tools and reinstalling gave me the latest sdk (12) and now this ROOT binary works :slight_smile:
