ld: -shared not supported

[ardeal]

Hi,

my envrionment:
ubuntu 20.04,
toolchain: riscv32-elf-ubuntu-20.04-nightly-2022.12.17-nightly.tar.gz
riscv-linux link: https://github.com/CSL-KU/riscv-linux

I would like to build riscv-linux and then run it on embedded RISCV MCU. I am experiencing the following issue

I searched the issue in Google, and found out a few links that are very similar with my issue:

riscv-collab/riscv-gnu-toolchain#335
riscv-collab/riscv-gnu-toolchain#803
larkmjc/busybear-linux#5

according to those above links, the most possible solution may be change a new toolchain. My question is: which toolchain I should use?

in the above 335 link, the answer is:
You have to use a linux toolchain instead of an elf toolchain to build the kernel.
it asks me to use a linux toolchain, where is it?
I am going to run the compiled linux on riscv, could I use the PC Linux toolchain? I got confused!!!
