"cannot compute suffix of object files" error occurs during the installation of RISCV toolchain

Question

I got an error shown on the terminal as the title, and the following errors in the config.log file, when I tried to install riscv tool chain:

Here are my configuration commands:

% mkdir /opt/riscv
% export RISCV=/opt/riscv
% ./configure --prefix="${RISCV}" --enable-multilib

I have tried to export LD_LIBRARY_PATH as /usr/local/lib, since i found a solution saying that the shared libraries may not be included. I also tried installing glibc package, since the log file mentioned this in the log file. But none of them works.

I am new to this environment and I'm not sure if there is anything missing. I would appreciate for any help.

Thanks in advance.
