Project cannot be built with both recent gcc and clang about mold

[rui314]

mold is written in C++20. You need a very recent version of clang or gcc as well as libstdc++. I'm using Ubuntu 20 right now, and even though I don't remember what packages I installed, I could set up a build env only with apt-get.

mold builds here on Arch Linux using Clang 11.1.0 (the latest released version), but not GCC 10.2.0 (the latest released version).

I tried by changing CXX and CC at the top of the Makefile to g++ and gcc.

btw, if the top of the makefile was:

CC?=clang
CXX?=clang++

instead of

CC=clang
CXX=clang++

Then CC and CXX would be respected when running CXX=clang++ CC=clang make.

I believe mold can now be built both with clang and with gcc.
