[Qemu-devel] Mac OS X issues

[Joachim Henke <joachim.henke@stud.tu-ilmenau.de>]

Ok, thanks for your reply.

I'm currently building qemu from CVS code several times a week, but I  
never had DOS related problems. The guest OS is Win98 SE and I use  
the DOS command prompt quite often. What are you doing, when it  
crashes qemu? Does this occur randomly or when running special  
programs/typing special commands?

Inspired by your e-mail I did some tests with the first "heavy" DOS  
application that came to my mind: FastTracker 2.09 - Ok, qemu is too  
slow to produce some enjoyable sound with it, but despite of this  
everything seemed to work well. While the track was running, I played  
around in the audio settings of FastTracker to tweak it a bit - and  
indeed: qemu crashed. Unfortunately, I couldn't reproduce this. Maybe  
it's just a bug in the SoundBlaster emulation which hasn't been  
totally completed yet?

My host is an iMac G5 with Mac OS 10.4.3 and Xcode 2.2 installed. I  
use the following options to configure the build:

configure --prefix=/usr/local --cc=gcc-3.3 --host-cc=gcc-3.3 --target- 
list=i386-softmmu --enable-coreaudio --enable-cocoa

Btw: Using "--cc=gcc" (which is gcc 4.0.2) also works fine.

I haven't tried FreeDOS yet, but if you like, you can point me to an  
image and give me some detailed instructions to reproduce the himem  
and xms issues.

Sincerely
	Jo.
