openssl dynamic linking from Cross.toml needs at runtime `libssl1.0.0` which doesn't exist anymore

[frederikhors]

In my project I need to use openssl not for the HTTP part of my app but because I need to decode a PKCS7 file.

I added to my Cargo.toml:

openssl = { version = "0.10.66", default-features = false }

and to Cross.toml:

[target.aarch64-unknown-linux-gnu]
pre-build = [
    "dpkg --add-architecture $CROSS_DEB_ARCH",
    "apt-get update && apt-get install --assume-yes libssl-dev:$CROSS_DEB_ARCH",
]

When I launch cross it builds but when the --release executable runs on Debian 12 machine with openssl installed the error is:

error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory

Why is it binded to libssl.so.1.0.0 and not to latest versions?

The openssl installed on the machine is:

openssl version -a

If I use ldd I get this:

Thank you all.

Having the same problem, target system has libssl1.1 & libssl3 available, but the cross build link's against 1.0.0.

I believe one way to workaround this would be to use a container that has one of those instead of the one used by default.

[frederikhors]

Yeah. They are going to upgrade the Docker images soon. I hope.

[Emilgardis]

Yes, this is planned!

[frederikhors]

Ok. I think we can close this.

[Emilgardis]

Reopening since it's not fixed yet

[thomas725]

Yeah. They are going to upgrade the Docker images soon. I hope.

Who are "they"? Is there an upstream project responsible for that? Where can I find the currently used docker container's definition?

[Emilgardis]

The definitions live here: https://github.com/cross-rs/cross/tree/main/docker

"They" would be the maintainers of cross-rs, so for example me :)

I've made a remark here about upgrading https://redirect.github.com/cross-rs/cross/pull/973#issuecomment-2397886693
