Error while building RISC-V tools

[Srikrishna Vasudev]

Hello everyone,

I am really new to RISC-V. I am trying to build the tools but keep getting this error. I am following the steps provided here:https://github.com/riscv/riscv-tools. 

I am not sure what I am doing wrong. Can anyone please help me out? Thanks!

Did you take cognizance of this comment at https://github.com/riscv/riscv-tools

"Several RISC-V tools that were previously maintained through this repository have since been upstreamed to their parent projects and are no longer included here. Your favorite software distribution should already have packages for these upstream tools, but if it doesn't then here are a handful of my favorites..."

What exactly are you cloning/building?

What configure options are you using?

What os variant and version are you building on?

My understanding is that at this stage if you really need/want to build the tools from scratch then you should build mostly or completely from upstream repos - e.g. gcc, binutils, gdb, newlib, glibc etc. Spike and openocd may be exceptions though.

Looks like you are trying to build riscv-tools.  This hasn't been properly maintained for years.  If you look at the submodules, you will see that they are mostly 3 years out of date.  This particular problem with riscv-tests was fixed many months ago.  I would suggest updating each submodule to top of tree.  Just cd into each submodule dir and do: git checkout master, git pull.  Except in riscv-openocd where you need to checkout the riscv branch instead of the master branch.

Thank you for the advice Jim, it worked.
