[Qemu-devel] "Will it blend?"

[Jonathan Kalbfeld]

Hello,

It's been a while since I built QEMU on Solaris.  Last build from the
spring time seemed to segfault due to some TCX issues.  Are these
present on Solaris still?

I'm looking to put up a new package on thoughtwave.com, if possible.

You mean TCG. Sparc64 host support on OpenBSD looks pretty good.
Sparc32 system emulation works, x86 gives bus errors. I haven't tested
other emulators, except the BSD user emulator that is under
construction.

On Linux/Sparc32/64 all emulators segfault but that is probably due to
glibc bugs. I haven't installed OpenBSD to my Sparc32 machine yet, so
I don't have a working reference platform for Sparc32. Therefore
Sparc32 host support is pretty much untested.

Based on this, I'd appreciate if you gave it a shot. There has been
much progress.

Would it even work on Sparc64/Solaris 10 any more?

Who knows? The only way is to try.

qemu no longer compiles on Solaris 10 due to C99 issues in
nbd.  It will compile on Solaris Express.

adding c99 or gnuc99 also doesn't work because of
anonymous unions not being supported.

GCC on Solaris doesn't support anonymous unions?  That seems bizarre.  
Or are you using the Sun compiler?

Is it block-nbd or qemu-nbd that doesn't work?  If it's the later, it's 
easy enough to prevent it from building on Solaris.

I don't remember. It's been a while since I tried to hack on it to get
it working.

It's block-ndb.
