Comment:

I'm trying to build the conda receipe using the command conda build . with the main branch. Getting error as

An unexpected error has occurred. Conda has prepared the above report.

• on inspecting i found that {{ stdlib("c") }} is being None when rendered. But i have installed gcc compiler. Am i missing something ?

Sorry if this is a silly question

[hmaarrfk]

you should likely prefer to use

conda build -m .ci_support/BUILD_THAT_YOU_WANT recipe

or

# install docker and stuff
python build-locally.py

Also i see that you have the defaults in your list of dependencies, maybe give
https://conda-forge.org/docs/user/transitioning_from_defaults/
