Description

@hiennd49

Hi everyone,

I'm trying to set up the Chipyard environment on Ubuntu x86_64, but the installation fails during build-setup.sh.

Environment:

  • Ubuntu Linux x86_64
  • Conda installed
  • Chipyard latest master branch
  • Running:
./build-setup.sh

The setup successfully creates the temporary conda environment, but it fails during the conda-lock stage.

Main error:

PackagesNotFoundError: The following packages are not available from current channels:

  - sysroot_linux-64=2.43*

Channels being used:

https://conda.anaconda.org/ucb-bar
https://conda.anaconda.org/conda-forge
https://conda.anaconda.org/litex-hub

Relevant log:

Could not lock the environment for platform linux-64

The following packages are not available from current channels:

  - sysroot_linux-64=2.43*

Full traceback ends with:

build-setup.sh: Build script failed with exit code 1 at step 1: Conda environment setup

Has anyone recently encountered this issue?

I'm wondering:

  1. Was sysroot_linux-64 2.43 removed from conda-forge?
  2. Is there a currently recommended Conda version for Chipyard?
  3. Should I manually downgrade the dependency version somewhere in the YAML files?
  4. Is there a known workaround for this setup issue?

Any help would be greatly appreciated.
Thanks!
