Root 6.24.00 homebrew building error

_ROOT Version:6.24.00
_Platform:mac OS X lastest
_Compiler: system default clang base on homebrew

Hi all:
I’ve try to upgrade root homebrew formula from 6.22.08 to latest 6.24.00 but building with errors (915.8 KB)

the error message

module map file '/usr/local/include/vc.modulemap' not found.

what should I do?


Hi @cxwx1,

Which git revision are you trying to build? There is a related commit by @vvassilev that should fix this problem, but it is only part of the master and v6-24-00-patches branches, i.e., the commit is not part of the revision tagged as v6-24-00. Therefore, if you are building from git tag v6-24-00, you may see this error under certain build environments.

Could you please try building branch v6-24-00-patches and see if that solves the problem?


testing OK v6-24-00-patches,
when should this patch accept by master branch? v6.24.02 or a revision of 6.24.00

I am confused. @cxwx1, can you confirm that v6-24-00-patches works for you?

yes, @vvassilev it works, my compiler info

╰─ clang --version                                                                                                                                                                                                   INSERT  5527  100%

and you can try using

although, it still have some problems like cannot find cfitsio, fftw and other library installed by homebrew, so you can see I add


just for a test

That seems an independent issue.

@oshadura may know if that was seen elsewhere.

I will add @henryiii to this discussion, since he is maintainer of ROOT package in Homebrew and probably can recomend something…
