Build ROOT from source on MacOS Monterey. ERROR: RInt.pcm is out of date

[Ela]

Hi, everyone!

I am trying to install ROOT (version 6.26.02) from source on MacOS Monterey 12.4. I got the following error:

"[ 86%] Built target Rint

[ 86%] Generating G__MathMore.cxx, …/…/lib/MathMore.pcm

<<< cling interactive line includer >>>: fatal error: module file ‘/Users/ela/root_build/lib/Rint.pcm’ is out of date

and needs to be rebuilt: could not read module signature

<<< cling interactive line includer >>>: note: imported by module ‘MathCore’ in

‘/Users/ela/root_build/lib/MathCore.pcm’

Error: Module ‘MathCore.pcm’ failed to load.

Error: Error loading the default rootcling header files.

make[2]: *** [math/mathmore/G__MathMore.cxx] Error 1

make[1]: *** [math/mathmore/CMakeFiles/G__MathMore.dir/all] Error 2

make: *** [all] Error 2 "

I tried to rebuild it many times, by following all hints in this similar post:

WSL Build from source error: RInt.pcm is out of date \ cannot read module signature

ROOT Version: v6.24.06 Platform: WSL (Ubuntu 18.04) Compiler: g++ 7.50 Hey everyone! I’m new to ROOT and I’m trying to build it from scratch on WSL using the default instructions from the main website. I’m using the latest stable build from Github. The configuration step goes through as expected without issue using cmake -DCMAKE_INSTALL_PREFIX=<installdir> <sourcedir> I’m then building with cmake --build . --target install and get the following (this is a non-clean build. The same error …

without succeeding. All of the dependencies required have been installed.

Does anyone know how to fix this issue?

Welcome to the ROOT forum.

Is it the first time you install it ? I mean your build directory is empty ?

[Ela]

Hi! It’s the first time I install it from source.
I mean I made many attempts to solve various errors I got, but I used “make clean” every time I tried to rebuild.

[couet]

Ok, as you get an error in MathCore may be @moneta has an idea.

Try “make -k” several times.

Hi! I just tried it, this is what I got:

Consolidate compiler generated dependencies of target rpdutil

[ 74%] Built target rpdutil

[ 74%] Built target ProofBenchPARFiles

make[1]: Target `all’ not remade because of errors.

make: *** [all] Error 2

make: Target `default_target’ not remade because of errors.

What are your cmake options ?

[Ela]

Sorry! I forgot to mention that.

cmake -DCMAKE_INSTALL_PREFIX=/Users/ela/root_install -DPYTHIA8=ON -DPYTHIA8_INCLUDE_DIR=/Users/ela/Downloads/pythia8245/include -DPYTHIA8_LIBRARY=/Users/ela/Downloads/pythia8245/lib -DCMAKE_CXX_COMPILER=/usr/bin/g++  -Dbuiltin_glew=ON -Dclad=OFF ../root_src

[couet]

Does it work if you do simply:

cmake -Dall=ON ../root_src

?

This is a known problem, see C++ modules: dependency issue on out of date Rint.pcm · Issue #10271 · root-project/root · GitHub

Done, but I got this : [ 74%] Linking CXX static library …/…/lib/librpdutil.a

[ 74%] Built target rpdutil

[ 74%] Generating …/…/etc/proof/proofbench/ProofBenchCPUSel.par, …/…/etc/proof/proofbench/ProofBenchDataSel.par

make: *** [all] Error 2

make: Target `default_target’ not remade because of errors.

[Ela]

I see. It seems there is no way to fix it so far, right?

If it’s just a “missing dependency”, then running “make -k” several times in a row should “overcome” it.
