Hello!
I am interested in running Solaris 8/9 under qemu. According to the thread below, it may be possible with more recent versions of OpenBIOS: http://qemu-forum.ipi.fi/viewtopic.php?p=10243
So I attempt to investigate. However, I am unable to build the alpha release of OpenBIOS from 20070427. I currently have qemu (20070501-svn-snapshot) Here are the details of my machine setup, and other variables, along with the output of the errors.

So, I notice that the package egcs64 may provide sparc64-linux-gcc, but I am unable to find such a package in debian/ubuntu or the sources to compile it myself. However, the google searches I made turned up only people on SPARC platforms running egcs64, so I am unsure what the requirements are to get to my intended goal -- Solaris 8/9 under qemu.
Any help is greatly appreciated! Thanks :-)
/bin/sh: sparc64-linux-gcc: not found
This would be a cross-compiler for Sparc64 target. Sparc64 emulation is not usable for anything yet, please try configuring for Sparc32 instead. That in turn needs sparc-linux-gcc, a cross compiler for Sparc32. If you have access to a Sparc machine (real or Qemu one), you can compile there with a regular gcc.

For what I need to test, I must use Solaris 8/9 on sparc64. sparc32 is not supported, as this is software which hooks kernel system calls.
So, why is sparc64 unusable, and what are the barriers to creating a fully usable sparc64 emulator which can run Solaris 8/9 (sparc64)? ie, how far away is it and what resources are lacking?

There are bugs in Qemu's Sparc64 CPU implementation that need to be found and fixed. Those prevent the OpenBIOS (or even simple C programs for the easier sparc64-linux-user case) from running. This part is just debugging, most things are in place.
When the CPU core is fine, OpenBIOS can probe for PCI devices, but the PCI bridge is not complete. Any real kernel would want to enable interrupts, but there is no interrupt controller yet. And so on. But implementing these is not very difficult.
Also OpenBIOS needs some work before any kernel will run, for example in the device tree and client interface. Should be easy.
For your specific system call problem, maybe you could implement a Sparc64 user emulator for Solaris, like the Linux and Darwin emulators. That would help by exercising the CPU core and finding the bugs.
