Problem linking shared library on MacOS

Dear experts,
I opened this thread before:

The problem was not solved.
I reinstalled the root from scratch.
Now I have root:

ROOT Version: 6.31/01
Built for macosx64 on Apr 02 2024, 07:12:29
From heads/master@62a7ea31

Yet I am having the same problem with linking the shared libraries.

A simple test case is kept here:

I am making the repository using cmake on my Mac:
inside the test repository:

  1. mkdir build
  2. cd build
  3. cmake ../ -DCMAKE_CXX_STANDARD=17
  4. cmake --build . --verbose

This is the verbose message during compilation:

_ROOT Version: 6.31/01
_Platform: MacOS (x86_64, Intel i9)
_Compiler: AppleClang 15.0.0.15000309


I will try locally . Which MacOS version do you have ?

Hi,
My MacOS version is 14.4.1 (23E224).
Thank you,
Arka

I tried on a similar machine with ROOT master. It installed without problem

git clone ....
mkdir build
cd build
cmake ../root
make -j8

Hi @couet ,
Thanks for checking this.
Just to clarify, you built the test repository from my Github, right?
From your commands, it looks like you built the root directory.

Anyway, root in my system still behaved weirdly.
I can run the basic root macros without any issue: but linking of libraries is giving me trouble.

This was the configuration command I used to build root on my system:

cmake -DCMAKE_INSTALL_PREFIX=/Users/arkasantra/Root6_Install -DPython3_EXECUTABLE=python3 -DPython2_EXECUTABLE=python2 -DCMAKE_CXX_STANDARD=17 -Dbuiltin_nlohmannjson=ON -Dhttp=ON -Droot7=ON -Dbuiltin_xrootd=ON -Dxrootd=ON -Dbuiltin_glew=ON /Users/arkasantra/root-6.31.01

The output of the configuration message is the following:

Oops … sorry I read to quickly I thought the issue was with ROOT itself. I just cloned your github and I tried on my Intel MacOS 12 machine and I get also errors… I must admit I do not know whats i wrong in your repo.

Hi @couet ,
Thanks for rechecking.
I also don’t know what’s going wrong in my repository.
This builds fine on a linux machine where root is sourced from CVMFS.

For example, this is what I did on my Linux machine:

source /cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase/user/atlasLocalSetup.sh
lsetup "views LCG_104c_ATLAS_2 x86_64-centos7-gcc11-opt"

Then I cloned my test repository and followed this:

cd test
mkdir build
cd build
cmake ../

This is the configuration message:

CMake Warning (dev) in CMakeLists.txt:
No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

After the command make, everything builds fine:

So it seems the problem of linking shared library is ONLY on the MacOS, not on Linux.
Best,
Arka

Hi @couet ,
Commenting here just so that the thread does not get closed.

May I know if there is any solution to the problem?
At present, I am using the docker version of the root on my Mac, which is essentially a Linux environment.
There things are working fine (as mentioned in my previous comment).

However, I will like to use root built on my Mac for operational ease.
Please let me know if you need anything else from me.

Thank you,
Arka

Did you try:

target_link_libraries(
    G__LUXESimEventDict 
    PUBLIC 
    ROOT::RIO)

or

target_link_libraries(
    G__LUXESimEventDict 
    PRIVATE 
    ROOT::RIO ROOT::Core)

Dear @pcanal,
I changed my CMakeLists.txt to:

target_link_libraries(
    G__LUXESimEventDict 
    PRIVATE 
    ROOT::RIO ROOT::Core)

but the linking is still a problem.

Here is the configuration output:

Dear @pcanal ,
Sorry for the late reply: I was very busy with something else.
Your suggestion of

-    G__LUXESimEventDict 
+    LUXESimEventDict

solved my problem, and now I do not have any issues compiling.

While we are at it, just for my own understanding, may I know why

G__LUXESimEventDict

worked for Linux and

LUXESimEventDict

worked for Mac?

Thank you very much,
Arka

On Mac the default is to require all the symbols of shared library to be resolved at the time that shared library is linked/created. On Linux it let you create shared libraries with missing symbols (that can be later provided by the executable). So on Mac you need to have the correct dependencies setup in CMake.
