Can't compile: Unable to detect OpenSSL version

[svenstaro]

I'm getting this trying to compile 1.14.0:

error: failed to run custom build command for `openssl v0.9.24`
process didn't exit successfully: `/build/rustup/src/rustup.rs-1.14.0/target/release/build/openssl-4e050bcc8f5aae18/build-script-build` (exit code: 101)
--- stderr

note: Run with `RUST_BACKTRACE=1` for a backtrace.

warning: build failed, waiting for other jobs to finish...
error: build failed

My rust is 1.29.0 and my openssl is 1.1.1. This is on Arch Linux.

Uh, I have the same error. Trying to install a crate called cargo-raze. I get the exact same error message.

Edit: Can anyone confirm that this is not a Arch Linux only compilation error? Maybe the PKGBUILD has some errors.

Got same issue on ArchLinux when installing cargo-clone:

Yet, OpenSSL is installed:

[mainrs]

make sure to downgrade your OpenSSL installation. I reverted to an old version from 2018/08/15 and it worked. Looks like the new OpenSSL 1.1.1 versions are incompatible with rust-openssl < 0.10.0 iirc.

[svenstaro]

I don't think downgrading openssl is a good idea in general.

[mainrs]

It isn't, but as long as the crates don't upgrade their rust-openssl dependency (which is actually a breaking change iirc) there is not really another choice as far as I could tell.

Edit: I'm not an Arch Linux expert but it might be possible to have to separate OpenSSL versions installed without colliding them. So that tools use the new one but rust gets compiled with the old one. I've read somewhere that you can pass a OPENSSL_PATH env variable but I am not sure if that still works. Compiling and installing the older OpenSSL version to another directory and linking against that one should make it work on your machine. Not sure how to do it if it has to be on a production PC.

[joelgallant]

I think this is what the openssl "vendored" feature is for - see https://github.com/sfackler/rust-openssl/tree/master/openssl#vendored

I'm not sure how to enable it for this scenario though, possibly just --features=openssl/vendored

[mainrs]

@joelgallant Ah nice catch! I will try to compile it with that option enabled. It shouldn't be much of a problem for development binaries/dependencies for local usage. Thanks for the hint!

[pickfire]

This is should be fixed after upgrading the version of reqwest to 0.9 which bumps the openssl crate for openssl 1.1.1 support. See https://github.com/sfackler/rust-openssl/blob/master/CHANGELOG.md#v0104---2018-02-18

I am working on this currently.

[g302ge]

I don't think downgrading openssl is a good idea in general.

but which version should be degraded to ?

[kinnison]

@leemaster This has been resolved for over two years. What are you asking about?
