ROOT-Build Fail on MacOS 12.1

[smd]

Hello,

I’m trying to build root on macOS v12.1 with these options:

cmake -DCMAKE_INSTALL_PREFIX=…/install/ …/root_src/ -Dminuit2=ON -Dpyroot=ON …/root_src/

And see this error:

[ 48%] Generating G__Core.cxx, …/lib/Core.pcm
error: entry with relative path at the root level is not discoverable
{ ‘name’: ‘’, ‘type’: ‘directory’,
^~
Error in modulemap.overlay!

Does anyone understand this?

Problem with root on macos: error: module 'Darwin' uses additional module map

Hi, I have ROOT 6.22/08, it has been working fine on macos Big Sur, now I updated to Monterey, updated Xcode, I had to install again the command line tools and now when I am running ROOT I get: Mareks-MacBook:~ marekwalczak$ root Desktop/test_mid.root input_line_1:1:2: error: module 'Darwin' uses additional module map '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/machine.modulemap' used when the module was built #include <new> ^ input_line_1:1:2: note: imported by module 'st…

ROOT 6.24/06 can not work on macOS Monterey

Please read tips for efficient and successful posting and posting code ROOT Version: 6.24/06 Platform: macOS 12 Compiler: Not Provided Dear ROOT experts, I have updated my macOS to macOS 12. The ROOT was installed by Conda on my MacBook. After I activate my Conda environment, the ROOT can’t be opened successfully as usual. The log is in the attachment. Is ROOT incompatible with macOS Monterey? Or do I need to reinstall the ROOT? Best regards, Zhuolin runRoot.txt (5.1 KB)

perhaps someone can advise. See I have a previous version of ROOT install and it worked on MacOS 12.1 until I updated XCode. So is there a way to just use that build if I just reverted back to the older version of XCode?

So it seems there’s no way to install any form of root on MacOS12.1 … is this correct?

In that case I installed the docker image…is it possible to use the docker image to look at data stored locally (I mean in a TBrowser or for analysis)?

Hi,
Which version of ROOT are you trying to install ? I have the master branch and 6,.26 branch working on 12.1 and latest XCode. You need to make sure you start with a clean build and using system libraries. Otherwise you can also use binary builds nightly from Index of /download/nightly

Hi,

it was the latest version, from source. I tried several things and none worked (source, brew, latest binary) and none worked. I have XCode 13 (since 13.1 didnt work and one of the other threads suggested switching back) and MacOS12.1. I’d rather have it from source since I want to use minuit2 but its not essential, I can find another machine to work on if I need to use that. In the end I was able to get this version to work: https://root.cern/download/root_v6.24.06.macos-10.15-x86_64-clang120.pkg . I’m not sure why it worked and others didnt though.

Thanks,
Sophie
