Sorry to be so late, was distracted. Not yet sure what to make of the above. The C++ should be C++11 or above. I would imagine Ubuntu Studio's install satisfies that. My older version of Ubuntu uses g++ v. 9.4 = C++ 201402. Let me know if you figure this out, I got some goo-goo'ling to do.

@michal-cab any progress ?

Not really. On Gentoo, that issue was solved by running "gcc-config -l" and then running gcc-config again to pick the "right" version of gcc. The version on this Ubuntu box is gcc 9.4.0. Also see https://wiki.gentoo.org/wiki/Upgrading_GCC#libstdc.2B.2B.so.6:_version_.60GLIBCXX_3.4.15.27_not_found and https://openmc.discourse.group/t/undefined-reference-to-throw-bad-array-new-length/3189 This system has libstdc++.so.6.0.28, not the newer libstc++.so.6.0.29 which has the offending symbol __throw_bad_array_new_length. On my Arch laptop, its up to gcc 13.2.1 and libstdc++.so.6.0.32. Hope that helps!
