Error when building root 6.26/06 on MacOS Monterey 12.6

I am getting the error when building root 6.26/06 on MacOS Monterey 12.6, with the latest XCode 14.0.1:

Hi @ivana,

Manually building ROOT is in general discouraged for regular users, unless justified otherwise. Take a look at more convenient procedure for macOS here.

If you want to continue your build anyways, I would recommend deleting all the *.pcm files in the output
directory in the hope that they get rebuilt, i.e.

$ find /Users/ivana/work/packages/root/root_v6.26.06_build/ -name '*.pcm' -print -delete
$ make

Cheers,
J.

Thank you; I tried your suggestion but I get the same error again. I use to build Root from sources as we need some options that are not set by default.

@Axel, have you seen this before?

@jalopezg

have you seen this before?

Yes:

• Build ROOT from source on MacOS Monterey. ERROR: RInt.pcm is out of date
• WSL Build from source error: RInt.pcm is out of date \ cannot read module signature

There’s a dependency problem somewhere; make -j4 seems to work around this issue :-/ IIRC @vvassilev wanted to have a look?

[ivana]

Thank you !
After removing all *.pcm, make -j4 went till the end and the installation succeeded.
