I am running Slackware Current on MIPS (Loongson) and am trying
to compile QEMU with GCC 3.4.6 using Glibc 2.5 and 2.6.18.1 kernel
headers. The build works fine except for warnings about linking PIC
code with no-PIC code but I get this error message when building Alpha
user emulation:

Since I am one of the people requesting Alpha user/system emulation I
wouldn't mind
helping to maintain Alpha user emulation and maybe even contribute to
Alpha system
emulation. The only thing is that I am very new to QEMU and still don't
understand
all of its internals. But I'm willing to learn by trial and error and
some RTFMing.
To that end I have over the last few weeks read through the Alpha
documentation
that I was pointed to by Wikipedia. I am also dabbling with MIPS on the
Lemote Fu
Long box and reading through HPPA documentation so I hope that this will
enable
me to much better understand the various RISC architectures and how to
implement
them in QEMU.
