rev 0.3.2 doesn't link against openssl 1.0.0

[tarcieri]

I've seen this issue reported once before and I haven't been able to reproduce it, even on the same Ruby versions.

Can you tell me what version of Ruby you were using and a little more about your environment?

[graaff]

Ah, I see what is going on here. On Gentoo we now have -Wl,--no-undefined in our standard ruby LDFLAGS, both for forward compatibility with ruby 1.9 and to let mix-and-match problems with our multiple supported ruby implementations fail early. This is what triggers the error, since the ossl_raise symbol (and the others) are unknown at link time but resolved at runtime by ruby loading openssl.so.

I can easily fix this on the Gentoo side for rev, but this may still be an issue for ruby 1.9 support. I'll leave the issue open if you want to investigate that, but feel free to close it.

On the Ruby 1.9 side, 1.9.2 has native support for non-blocking SSL. I'm afraid my hacks to support it on 1.8.x are brittle due to this problem, and I think the only solution is to discontinue support for SSL on 1.8.x.

I've added rev as a supported package in Gentoo so that we can work around our own --no-undefined feature for it. If people are running Gentoo and run into this issue then please tell them to install the Gentoo package instead.

I think the best solution may be to split off SSL support into its own gem. There's already the openssl-nonblock gem... I'd like to make a rev-ssl gem which uses this.
