Started over from scratch, installing everything in Ubuntu 13.10 in a VirtualBox. I used the code.ethereum.org tarball. (downloaded this morning)
I had to do two things differently from the instructions:
1) I had to issue: "sudo apt-get install qt5-default" in order for alephzero to build.
2) I had to edit cpp-ethereum-poc-1/alephzero/alephzero.poc to correctle append "-poc-1" to "cpp-ethereum" in the INCLUDEPATH
alephzero runs, and here's what I tried so far:
Clicking Mine adds 1b wei, but doesn't seem to do anything beyond that.
Clicking Connect opens a window, in which I entered: "18.104.22.168:30303" this added a line to the leftmost pane, and I can see in the terminal that my client is attempting a bunch of additional connections. They either go to "Connected." or "Connection refused (connect: Connection timed out)" but no changes appear in the leftmost pane of the client gui. Also, the client greys out, or goes dim on me, and I can't interact with it any more.
Do I just need to wait for the connection attempts to finish? Or will my client perpetually try to find new connections? Is the greyed out window a problem? Should I eventually see more than one peer? (I've seen a ton of "Connected." messages in the terminal, but nothing in the client's gui window.
