unrecognized argument in option ‘-mcmodel=medany’

Hi,

On ubuntu 18.04, I am experience the following issue when I run bash build.sh in riscv-tools folder:

Removing existing riscv-isa-sim/build directory

gcc: error: unrecognized argument in option ‘-mcmodel=medany’
gcc: note: valid arguments to ‘-mcmodel=’ are: 32 kernel large medium small; did you mean ‘medium’?

Seems very similar to https://github.com/riscv-software-src/riscv-pk/issues/204 — I can’t help further, but maybe you’ll find some inspiration there.

@aswaterman Thank you! I just notice that I misunderstand risc-tools and riscv-gnu-toolchain.

I just now downloaded riscv-gnu-toolchain from:

1. https://github.com/riscv-collab/riscv-gnu-toolchain/releases/download/2022.12.17/riscv64-elf-ubuntu-20.04-nightly-2022.12.17-nightly.tar.gz
2. https://github.com/riscvarchive/riscv-fesvr
3. https://github.com/RISCV-Tools/riscv-tools

then I tar the tool to /opt/riscv folder.

In my bashrc file, I added: export RISCV="/opt/riscv" export PATH=$PATH:$RISCV/bin and run source ~/.bashrc

when I run ./build.sh in riscv-tools folder, I encountered the following issue:

it seems that I used 64bit riscv toolchain, but the makefile used 32bit libs.

how to set the makefile to run in 64bit mode?
