[Jerker Nyberg]

Hello,

I tried to compile qemu on Alpha but cannot get it to work. I use
gcc-2.96-112.7.1 (?) on a Red Hat Linux 7.1 distribution with
kernel-2.4.3. 

I removed the "CFLAGS += -msmall-data -msmall-text" to get the compilation
going, but got stuck later again at "./dyngen -o op-i386.h op-i386.o" with
"dyngen: ret expected at the end of op_raise_interrupt". See log below.

Sorry if qemu development is in a too early stage to bother you with these
kind of questions.

By the way, to testdrive Linux on ARM go here:

Jerker Nyberg.

Hmm, very weird. Must be a quirk of your compiler, maybe it doesn't
understand -fno-reorder-blocks -fno-optimize-sibling-calls
properly. 2.96 is pretty ancient and not even an official gcc release,
so I am not sure anybody is interested in making qemu work with
it. I'd advise to upgrade to 3.3.

Also, kernel 2.4.3 doesn not support getting the fault address in a
signal handler (unless Red Hat patched that in). I don't know how
essential that is for qemu, though.

Finally, qemu does currently not work on Alpha anyway, and only worked
for very simple programs previously, maybe Fabrice will have a look at
it, I don't have time currently, unfortunately.
