It first told me that my automake was outdated so I updated automake and autoconf. Then it told me I needed x11 so I installed xquartz. And now its giving me these errors which I was unable to google. I am running OS X 10.10
To clarify, even if you get all the tools to build and link the project, the resulting binary will not function, as various protective features rolled into GCC post-4.5 will prevent SheepShaver's unorthodox methods of emulation. And yes, this does mean that running SheepShaver opens your system up to a number of malicious attack vectors while it is running. However, I doubt anyone is targeting SheepShaver exploits as a common attack vector on OS X, Linux or Windows, so the build via 10.6 method should be safe enough
Not that I don't mind having 10.6 kicking around, I just don't like I can't figure out why my pcap stuff bombs on Sheep, but works fine on Basilisk II...
don't do today what you can put off until tomorrow.
