Re: [ptxdist] [PATCH 3/3] python3-cryptography: Python package that wants to compile with rust and cargo...

["Artur Wiebe" <artur@4wiebe.de>]

Hi,

cryptography is a python package that uses setuptools-rust to compile a module with rust/cargo.
This is the first one in PTXdist, but I think it will not be the last.
It is needed by python3-asyncua (OPC/UA) that I am trying to add.

While pure cargo packages already work well (I've tried few weeks ago), the python-setuptools scenario is not covered yet.

I am not that deep into PTXdist so I could send a patch. I hope someone can help.

My suggestion is to add a PKG_CARGO_LOCK variable that points to the Cargo.lock file.
If it exists ptxdist cargosync should use it and also CARGO_HOME should be set in env. 

PYTHON3_CRYPTOGRAPHY_CARGO_LOCK := $(PYTHON3_CRYPTOGRAPHY_DIR)/src/rust/Cargo.lock

BR,
Artur
