What happened?

I'm trying to use conda-build for the first time. I'm trying to build sqlite from the conda-forge feedstock. I get:

@opoplawski What does your condarc say? Are you pointing at conda-forge channels or the default channels?

[opoplawski]

I've updated the initial report to add more info. I'm just pointing at conda-forge. We are using an internal mirror that I've redacted the URL for, but it should be identical to upstream.

[opoplawski]

I guess these come from the requirements:

requirements:
  build:
    - {{ compiler('c') }}
    - {{ stdlib("c") }}
    - make  # [not win]

And presumably stdlib("c") is resolving to c_linux-64? No idea how any of that works though.

[opoplawski]

It appears to get farther if I get rid of all instances of stdlib("c") in the recipe/meta.yml file, but fails with:

/export/home/orion/conda/envs/conda-forge/conda-bld/sqlite-split_1753994936565/work/conda_build.sh: line 9: HOST: unbound variable

[opoplawski]

Which again appears to be coming from the sqlite recipe:

set -euxo pipefail

# Prevent running ldconfig when cross-compiling.
if [[ "${BUILD}" != "${HOST}" ]]; then
  echo "#!/usr/bin/env bash" > ldconfig
  chmod +x ldconfig
  export PATH=${PWD}:$PATH
fi

But why is HOST not getting propagated to the build script?

Sure enough, HOST is missing from the work/build_env_setup.sh script - but why?

[opoplawski]

So apparently I needed to define a conda_build_config.yaml file with something like:

c_stdlib:
  - sysroot                     # [linux]
  - macosx_deployment_target    # [osx]
c_stdlib_version:
  - 2.17                        # [linux]
  - 10.13                       # [osx]

in it. This resolved my issues. It was not apparent to me from a cursory reading of the getting started docs that this was necessary.

[ryanskeith]

@opoplawski, I agree that documentation is missing. Where would you have liked to have the documentation for this to have been located? Also, what error message would you have liked to see?

[opoplawski]

Not sure, but some suggestions:

• The templates section of https://docs.conda.io/projects/conda-build/en/stable/concepts/recipe.html
• https://docs.conda.io/projects/conda-build/en/stable/user-guide/tutorials/building-conda-packages.html

Ideally you would see something like No definition for c_stdlib in conda_build_environment.yaml.
