I just read that Bochs has a carbon version, I downloaded it, did ./configure --with-carbon. A few minutes into make the errors start to fly

Any ideas what to do about this?

Tried the pre-built binary that's available on their site?

Works for me...

Too bad I don't have an OS to run on it, other than the Linux image they provide...

Anyone know if this works with VPC images?

[absmiths]

What I want to know is how fast is it in comparison to VPC? I realize that VPC is a more complete emulator (given that it accomodates a wider range of OS's), but if bochs can achieve near par performance with it's OS 9 counterpart (is there one?) then that would be telling...

I hadn't seen the 1.21 OS X binary, I wanted to see the 1.3 in action.

Actually, it compiles for me, but you're right, the carbon.o file doesn't get built correctly. On my system (OSX 10.1 build 5M28) it links against the X11 libs, and works just fine with XDarwin. Maybe we need the new developer tools that apple only released to developers who pay .

But, right now I'm running "DLX Linux", a very small 10 meg linux distro, and it works fine. The CPU emulated is an original pentium 60/66! Quite an unloved chip, if my memory serves me correctly. Maybe i'll try some linux images from the bochs site and see if i can make it work any faster.

Or wait for a binary

Ok, I don't think this is a replacement for VPC . VPC5 may be really slow under OSX, but bochs is REALLY slow . For the past 10 minutes i've been watching it try to boot OpenBSD, and it still hasn't even finished. It loaded that dlx-linux pretty quickly, but that was using an ancient linux kernel (something from the 1.3 series). I think you're better off with VPC ... unless the carbon version is REALLY fast or something ...

Whether or not Bochs is a viable VPC replacement depends on what you want out of it. If you want to play Half-Life or render 3D animation with some obscure Windows-only program, then no, Bochs isn't going to help you. Same goes if you want to crunch RC5 or SETI.

If, on the other hand, you're doing non-performance-intensive stuff, Bochs should work fine. In cases like these, you're generally talking about running specific programs with no direct Mac counterparts (mostly games, and even then mostly games in specific genres that don't generally require high performance).

Note: If you turn on some optimizations when compiling Bochs, you can boost the speed significantly. I find -O4 seems to work very nicely.
