Build fails with "error: 'L_tmpnam' was not declared in this scope"

[k138z]

I am on Ubuntu 22.04.4 LTS. I tried building Spike on both commit hashes 20a2b6d0 (what riscv-gnu-toolchain has) and the latest master (c81d8e73). My configure arguments are as follows: ../configure --prefix=$RISCV --host=riscv64-unknown-linux-gnu

Here is what I get on make:

All help appreciated, thanks!

Drop the --host argument. I assume you are trying to compile Spike as a native binary for your workstation.

Sorry, yes. I had a fundamental misunderstanding about how all of this works - is not an issue now. Closing.

Hi there, I met a similar problem, though I do not have host option. I am trying to compile Spike as a native binary as @jerryz123 said ../configure --prefix=$RISCV

The error is

The problem is encoding.h is not updated in my local environment. Once updated, problem fixed.
