TBrowser issue about root

[couet]

We had that some time ago but it was fixed. What is your processor? Intel ? M1 ? M2 ?

I just rebuilt ROOT on an arm machine with MacOS sonoma. It works for me:

I have a MacBook Pro M2 Max (2022)

I compiled a ROOT stable tagged version few days ago. May I ask which one you just compiled ?

What was the origin of the issue in the first place ? Perhaps it might help finding the reason why this happens again.

Thank you.

I have tried on a Mac Mini with the M2 processor, MacOS 14.3 and clang 15. I used the master version of ROOT.
The PR fixing this issue is: #13885
@TimurP made it.

I did:

   git clone https://github.com/root-project/root.git
   mkdir root-build
   cd root-build
   cmake ../root
   make -j8
   source bin/thisroot.sh
   root -web=off

Just for completion, I have a Clang16 with MacOS 14.2.1.

Could you point me a specific commit or you just compiled the master version recently ?

I just compiled the master version
Clang 16 ? ... I haven't tried.

I look at this page to know which Xcode version corresponds to a given MacOS version.
-> It tells me that for 14.2 it is Xcode it is Xcode 15.2
I look at this page to know which clang version corresponds to a given XCode. version.
-> It tells me that for XCode 15.2 it is Clang 15.0.0

From the cmake log in ROOT it shows:

-- Clang version: 16.0.6
[...]
Compiler: AppleClang15

Not sure which one to trust. Other libraries I am using are showing Clang15.

I bypassed the cmake issue using the builtin_glew suggestion.
cmake.log

Looking more closely I can see many error message as following. I am not sure about the origin of these lines.

ERROR in cling::CIFactory::createCI(): cannot extract standard library include paths!
Invoking:
  LC_ALL=C clang   -xc++ -E -v /dev/null 2>&1 | sed -n -e '/^.include/,${' -e '/^ \/.*++/p' -e '}'

Except this, there is no issue anymore. The most recent master doesn't have this white blank issue.
Thank you for pointing the solution.

It appears this issue is closed, but wasn't yet added to a project. Please add upcoming versions that will include the fix, or 'not applicable' otherwise.
