Subject: Re: [GSoC] building JtR for MIC

You're right about the syntax, but that's not my point.

I mean that when you're configuring for a x86 machine, you don't have to add those flags (“-lssl -lcrypto”) manually, since they'll be added into Makefile automatically by the autoconf scripts.

But when I configure for MIC, those flags just disappear in Makefile so I have to add them by myself. I think there's something wrong with the autoconf scripts, and I'm still trying to fix that.
