Re: [B2-devel] Intel emulator dies when emulating 68040?

[Bassie <jea...@te...>]

hey there, first of all congratulations for all you've done in the
emulationscene for all of us ! daily i follow messages at the
emaculation-forum ! people there start thinking that Sheepshaver isn't
worked on by its developper anymore, and that the chances on any updates
would be practically nihil, which is understandable as it has almost
become a worthy stable application. But at the forum you will read that
most people (as myself to) are having the greatest difficulties in
getting network working ! Yeah I know that in linux or osx platform the
difficulties are bypassed by slirp settings ! but here at work we are
obliged to use basilisk II with its ethernetdriver to load fonts to a HP
printer for use on a amos (alpha-micro)-system ! And of course most of
us are poor windows users with very little knowledge ! If just you could
find a way for us to use the basilisk-ethernet driver for windows
without SS exiting or crashing ! so that in a lan-environment (mac-win)
we could forget about basilisk as it isn't powerpc compat.
hope didn't ask to much and if due lack of time or any other reason, for
you this would be inpossible, I will understand that too, I'm already in
your debt for how it works right now

Thx. in avance and for everything

JM. Bastiaens

Hi,

I get a similar problem with the pure MacOS X port (building from 
MacOSX/) unlike building from the Unix/ directory with SDL support. I 
have not really investigated why, neither did I try to set the 
emulation to 030. Actually the crash can occur at any time.

It could be a miscompilation (which is not unsual on that platform), or 
some stack alignment problem but there should not be any nowadays. i.e. 
reminder: it works with a Unix/ + SDL port.

Does it work with 030+FPU?

BTW, I also tried to fully build from the command line. It works on 
PPC, but B2 dies the same way on Intel. Some flags may be missing on 
Intel side. Anyway, I'd probably commit this too as I'd prefer building 
the whole emulator from command line and only use e.g. Interface 
Builder to update the GUI.

I tried to gdb it but it was not very useful. :-(

I may try again to debug on this weekend.
