Meshing Tests Fail (Mac M1)

[lkuna24]

Upon trying to install neper on an Apple M1 laptop(OS Ventura 13.6.1), I am running into issues with the meshing module.
I installed gmsh:

kuna138@WE46980 build % gmsh --version
4.13.0-git-4bf968b8f

and am using homebrew installed OpenMP and compilers:

CC=/opt/homebrew/Cellar/llvm/17.0.6_1/bin/clang CXX=/opt/homebrew/Cellar/llvm/17.0.6_1/bin/clang++ cmake .. 

The cmake and compile seem to work without any issue. I will note the warning at the end of the compile, but I don't think this is cause for concern:

ld: warning: ignoring duplicate libraries: '-lgsl', '-lgslcblas', 'contrib/muparser/libmuparser.a', 'contrib/nlopt/libnlopt.a', 'contrib/openGJK/libopenGJKlib.a', 'contrib/orilib/liborilib.a', 'contrib/scotch/libscotch.a', 'contrib/scotch/libscotcherr.a', 'contrib/scotch/libscotcherrexit.a', 'contrib/ut/src/libut.a', 'neper_t/libneper_t.a', 'neut/libneut.a'
[100%] Built target neper

I run the tests and am running into some failures:

Errors while running CTest

And of course running the examples from the Neper tutorial works fine for -T module:

kuna138@WE46980 build % ./neper -T -n 10 -reg 1

and when I move to the mesh module, I get a failure:

Are there any suggestions for what could be wrong with this build?

Thanks,

I have the same error for Mac M2. Typing the following statements in the terminal solved it for me, but I guess now there is no multi thread calculation.

export CC=/usr/local/opt/llvm/bin/clang
export CXX=/usr/local/opt/llvm/bin/clang++
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"

I am currently using MacBook Air M1 with MacOS 15 (beta system), the same problem occurred.
To solve it, I downloaded the Xcode and then the problem can be solved.
