Hi,
I'm trying to compile a Rust package using the C compiler provided using the conda package manager.
conda allows you to specify a compiler that is needed for the build recipe in the meta.yaml file. For example:
requirements:
host:
build:
- {{ compiler('c') }}
run:
During the build stage, the compiler is installed in a custom location and the appropriate environment variables are set:

This works well when compiling C / C++ libraries. However, rustc does not seem to use the environment variables, and fails with a error: linker `cc` not found error. The complete build log can be found here: build (#53928151) · Jobs · ostrokach / uniparc_xml_parser · GitLab.
Is there any way to make rust use cc that my $CC environment variable refers to (/opt/conda/conda-bld/uniparc_xml_parser_1519326308747/_build_env/bin/x86_64-conda_cos6-linux-gnu-cc)?
Thank you!
