Compilation error on macOS 15

ROOT

ROOT Version: 6.36.04
Platform: macOS 15.6.1
Compiler: Apple clang version 17.0.0 (clang-1700.3.19.1)

I’m trying to compile the ROOT 6.36.04 with the following cmake configuration:

cmake -D roofit=ON -D Python3_ROOT_DIR=/Users/dinardo/Homebrew/Cellar/python@3.11/3.11.7/Frameworks/Python.framework/Versions/3.11/ -D CMAKE_CXX_STANDARD=17 -D CMAKE_INSTALL_PREFIX=/Users/dinardo/rootDir/myInstall/ ../

Here are the error messages:

Let me know.

Kind regards,

Try completely erasing /Users/dinardo/root/myBuild/include
and restart the build.

Thanks for the suggestion, but I get the same errors.

Can you recheck that you really have 6.36.04 ?

If I download https://github.com/root-project/root/releases/download/v6-36-04/root_v6.36.04.source.tar.gz

I see in file TTree.h:432
virtual Int_t BuildIndex(const char *majorname, const char *minorname = “0”, bool long64major = false, bool long64minor = false);

The same with: https://root.cern/download/root_v6.36.04.source.tar.gz

In contrast, you seem to have an outdated file:

TTree.h:432:28:

432 | virtual Int_t BuildIndex(const char *majorname, const char *minorname = "0");

5

To Download the version I’m using use the command:

git clone --branch latest-stable --depth=1 https://github.com/root-project/root.git` rootDir`

Is there another way to do it “more” properly?

6

That’s also correct. If I do that on a clean folder, I see:

grep BuildIndex ./rootDir/tree/tree/inc/TTree.h | grep virtual
virtual Int_t BuildIndex(const char *majorname, const char *minorname = “0”, bool long64major = false, bool long64minor = false);

compare to the error log you were showing, which said

virtual Int_t           BuildIndex(const char *majorname, const char *minorname = "0");

Try removing everything (source, build and install folders) and starting a clean build.

7

I get the same error, also because when I download it from git the directory is brand new already.

8

Can you post here the result of:

sudo updatedb
locate TTree.h

And then:

grep BuildIndex /your/file1/TTree.h | grep virtual

etc for each found occurrence of locate.

Hello @mauroroot,

this looks like there might be an older root installed in a system directory, and the compiler is finding its headers first. Could this be the case?
I think the above post is looking in the same direction.

Dear All,
many thanks for your suggestions. Indeed that was the case, somehow CMake was looking into another ROOT installation.

I fixed that, and now it’s compiling like a charm.

Sorry for the noise.

Kind regards.
