Re: NetBSD-HEAD amd64 refuses to build

Sure I tried without -c, went into the debugger prompt.

At point in the boot process did you end up in the debugger? (What was
on the screen?) Did a backtrace "bt" give any clues?



Basically, I'm lost with the debugger, and the best I can do is type

As Patrick suggested, please try typing "bt" in the debugger, to get a back-trace.

Is there any documentation?

Yes - see "man 4 ddb"

But I don't think the debugger could really help me.

It certainly won't help if you don't try, and don't listen to other people who are trying to help you.

I remember in the boot process getting past athn0, so that was
detected apparently satisfactorily.

I have packages built for amd64 but nothing that survives for
NetBSD-current i386, and I don't want to restart from scratch building
packages for amd64.

If you can't get the kernel running and stable, you are a long ways away from having to think about building packages.

I remember building modular-xorg from pkgsrc, but startx failed on
inability to find display.  This also happens with OpenBSD 5.4 Live
USB from which was supposed to have
been already configured and ready to go.

There needs to be a way to single-step through the boot process;
otherwise, boot messages whiz past too fast to be readable, and I
still don't know any way to capture these messages to a file when boot
falls short.

Try using a serial console and capturing the output.

The messages are also stored in the kernel's message buffer, where the debugger can access them.

And, if you were to type "reboot 0x100" you could force a crash dump.
