OpenSSL version error during installation

[sridharraman]

Trying to install using cargo install timetable throws this error:

error: could not find timetable in registry https://github.com/rust-lang/crates.io-index

When I try to install from source, I get an error related to the version of OpenSSL:

error: failed to run custom build command for openssl-sys v0.9.23
...
This crate is only compatible with OpenSSL 1.0.1, 1.0.2, and 1.1.0, or LibreSSL
2.5 and 2.6.0, but a different version of OpenSSL was found. The build is now
aborting due to this version mismatch.

Any idea what I can do?

Thanks for opening the issue! What OS and Rust/Cargo versions are you using?

The project has not been published on crates.io because at the time it was depending on a crate from a git repo, and that might not be necessary anymore. I'll look into updating the dependencies, see if I can publish it, and if the update might solve your problem.

I am using Ubuntu 18.04 and the latest versions of Rust and Cargo.

[vinc]

Strange, with Ubuntu 18.04 it seems that you have OpenSSL 1.1.0 and the openssl crate claim to be compatible with it. I found an issue with the next version 1.1.1 here: sfackler/rust-openssl#994

I updated all the dependencies of this project and switched from openssl version 0.9.23 to 0.9.24 so maybe that'll fix your issue if you try to build it again after pulling the change?

And I'll try it too later today on Arch Linux with the latest Rust and Cargo so if there's an issues with the latest version of OpenSSL on the system I'll probably be able to reproduce it.

I was also hopping that transitfeed has been updated in that time so I could publish the crates but that don't seem to be the case: https://github.com/bfrog/transitfeed/releases

I actually have 1.1.1b. Could that be the problem?

I re-pulled the changed code and tried building it. This is the error I get:

error: failed to run custom build command for openssl v0.9.24
thread 'main' panicked at 'Unable to detect OpenSSL version',

So, the option for me is to downgrade to 1.1.0?

[vinc]

No don't downgrade, it's my project's responsibility to work with recent versions of OpenSSL if that's the issue. And it seems that this is indeed the issue! Worst case it seems that I'll need to adapt the build instructions while waiting for the openssl crate to be fixed.

Thanks @vinc

For now, I have another container which has an older version of OpenSSL. It works fine there.

[vinc]

Okay I could reproduce the problem on my Arch Linux computer with OpenSSL 1.1.1b! I updated the reqwest crate that has a lot of dependencies including openssl that got updated too. And now the issue is resolved I think.

I'll add @dependabot to this repo to stay up to date.

(I also found a lot of changes on the local repo of this computer that I had not committed, I'll have to check that)
