Undefined C++ symbols from homebrew installation on MacOS arm64

[zippylab]

Has anyone seen undefined C++ symbols like this from the linker on MacOS when using the homebrew ADIOS2 package?

Undefined symbols for architecture arm64:
  "adios2::Variable<double> adios2::IO::DefineVariable<double>(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char>> const&, std::vector<unsigned long, std::allocator<unsigned long>> const&, std

I'm using the homebrew gnu compilers (g++-14, gcc-14, gfortran-14) via OpenMPI wrappers to compile the application linking against ADIOS2.

Interesting. No, I don't think anything has gone by about the homebrew recipe. Offhand, there are no noticeable red flags in either the error output or in the XGC source.

Thanks, @eisenhauer . N.B. I also built ADIOS2 myself using the homebrew gnu compilers, and saw the same undefined symbols linking against that. Maybe it's something to do with C++ libraries linkage on MacOS that I'm getting wrong.
