CMake CXX and AfterImage errors on Mac OS 15.4

ROOT
1

After updating to Mac OS 15.4 + latest Xcode etc I am unable to run cmake on todays origin/master:

The command I run is:

cmake -DCMAKE_INSTALL_PREFIX=/opt/hep/root/main_April4_2025 /Users/markhodgkinson/root_src_April2025 -GNinja
-DCMAKE_BUILD_TYPE=Release
-DCMAKE_CXX_STANDARD=17
-Dfail-on-missing=ON
-Dgdml=ON
-Dx11=ON
-Dpyroot=ON
-Ddataframe=ON
-Dmysql=OFF
-Doracle=OFF
-Dpgsql=OFF
-Dsqlite=OFF
-Dpythia6=OFF
-Dpythia8=OFF
-Dfftw3=OFF
-Dbuiltin_cfitsio=ON
-Dbuiltin_xxhash=ON
-Dbuiltin_afterimage=ON
-Dbuiltin_openssl=OFF
-Dbuiltin_ftgl=ON
-Dbuiltin_glew=ON
-Dbuiltin_gsl=ON
-Dbuiltin_gl2ps=ON
-Dbuiltin_xrootd=ON
-Dgfal=OFF
-Ddavix=ON
-Dbuiltin_vdt=ON
-Dxrootd=OFF
-Dtmva=ON

which gives the following errors:

– The C compiler identification is AppleClang 17.0.0.17000013

Is there a solution?

Hi @Mark_C_Hodgkinson,

Thank you for your question.

Can you try setting this OFF after installing libpng on your system? (can you try pulling the latest master, if not already? We had a few patches to fix this recently)

Cheers,
Dev

Hi,

I’m not sure how to install libpng. Can you advise?

If I set -Dbuiltin_afterimage=OFF the afterimage error vanishes, but these remain:

– Detecting CXX compile features - done
CMake Error at CMakeLists.txt:62 (string):
string sub-command REPLACE requires at least four arguments.
Call Stack (most recent call first):
CMakeLists.txt:72 (strip_path)

CMake Error at CMakeLists.txt:62 (string):
string sub-command REPLACE requires at least four arguments.
Call Stack (most recent call first):
CMakeLists.txt:76 (strip_path)

and I also see a new warning:

– Cling version (from VERSION file): ROOT_1.3~dev
CMake Warning at interpreter/cling/lib/Interpreter/CMakeLists.txt:282 (MESSAGE):
Cannot determine location of C++ headers for runtime.

I already have the latest master I think:

markhodgkinson@IT-Asset-0000002240-MacBook-Air root_src_April2025 % git fetch origin

markhodgkinson@IT-Asset-0000002240-MacBook-Air root_src_April2025 % git pull

Already up to date.

Cheers,

I also just tried:

brew install libpng

and then rerunning cmake with the afterimage off/on - the results reported in previous messages do not change.

Thanks,

Mark

Can you check if you made any changes here (or see if there is a git diff) to get ROOT building?
Also trying a clean build might help (especially after the upgrade to a newer version of macos).

Let me know if that works.

Cheers,
Dev

I have not made any changes to ROOT (git diff confirms this) and I have a fresh clone and build directory after updating to Mac OS 15.4

Thanks,

Mark

That is strange. Maybe @couet can help?

If I switch to the 6.34 branch:

git checkout v6-34-00-patches

then all the errors vanish, except the afterimage one - that can be resolved too by choosing:

-Dbuiltin_afterimage=OFF

though I am unsure what functionality I lose by doing that.

Cheers,

Mark

Should be fine. The preinstalled one will be used.
