molds makefile uses -std=c++20, gcc versions before gcc-10 don't understand this but demand -std=c++2a I tried to patch the file and go ahead with gcc-9 just for fun, but that makes it only more angry with stash headers missing errors, which seems like a dead giveaway of incomplete c++20 support in the compiler. from the readme.md: mold is written in C++20, so if you build mold yourself, you need a recent version of a C++ compiler and a C++ standard library. GCC 10.2 or Clang 12.0.0 are recommended.
