The Ubuntu package you installed includes the compiler binary riscv64-unknown-elf-gcc, not riscv64-unknown-linux-gnu-gcc.

If you want to use a Linux build, then the package is gcc-riscv64-linux-gnu (https://packages.ubuntu.com/search?keywords=gcc-riscv64-linux-gnu) and the compiler is invoked likewise.

Okay to close.

Could you close it so? I think that only the issue originator or those with elevated privileges in this repo can close it.
