Enable Rust compilation on conda-forge ?

[PIERRE AUGIER]

To get Mercurial built with Rust on conda-forge (https://github.com/conda-forge/mercurial-feedstock/pull/37), we first need to be able to build it locally using conda-forge.

I tried something simple but I get an error:

conda create -n env_hg_rust setuptools rust -y
conda activate env_hg_rust
cd Downloads/mercurial-5.6
python setup.py --rust install

which ends with an error related to the fact that the linker can't find libz:

note: /data0/opt/miniconda3/envs/env_hg_rust/bin/../lib/gcc/x86_64-conda-linux-gnu/9.3.0/../../../../x86_64-conda-linux-gnu/bin/ld: cannot find -lz

I find it strange that /data0/opt/miniconda3/envs/env_hg_rust/x86_64-conda-linux-gnu/bin/ld can't find /data0/opt/miniconda3/envs/env_hg_rust/lib/libz.so.

I tried simple things with LIBRARY_PATH and LD_LIBRARY_PATH but without success.

I don't know if it is something related with Rust or just a conda bug.

Do you understand why I get this error?
