qemu @1.6.0+target_i386+target_m68k+target_mips+target_ppc+target_sparc+target_x86_64 - qemu-system-sparc broken - compiler issue?

[d0wntime]

When I use the qemu-system-sparc built by MacPorts, it freezes during the emulated machine's startup process. When I build it using gcc-apple-4.2, I have no such problem.

Thanks for the ticket. In the future, please Cc relevant port maintainers (port info --maintainers) and use WikiFormatting in ticket descriptions.

When I build it using gcc-apple-4.2, I have no such problem.

Which compiler had you used before?

[cooljeanius (Eric Gallager)]

Cc Me!

There were various problems with QEMU using TCG/TCI when clang support finally arrived upstream. The i386 and x86_64 targets work fine for me with clang for some time now. I guess they are generally the targets with the best test coverage by users. I did not have time yet to reproduce the issue with the SPARC target you reported in the ticket.

I would advise to report the issue upstream as well.

[raimue (Rainer Müller)]

Please test again with qemu @1.6.1_0. I am now able to run qemu-system-sparc -cdrom ~/src/img/debian/debian-7.1.0-sparc-netinst.iso, which just hung before coming up with video output at all. However, I am dropped into an OpenBIOS shell only and I don't know how to proceed. So, please run your test case to verify if this bug can be closed.

It works, thanks! I think you can close the bug report ...

... that said, I found another issue of sorts. Qemu isn't linked against libSDL ... can it be? Should I create another ticket to request this to happen? If you link it against SDL, you've got graphics.

Replying to peter@…:

QEMU uses a native Cocoa frontend on Mac OS X instead of SDL. Graphics are supported and work fine for me.
