Hi,
just a followup on this subject.
I managed to setup GCC as the primary compiler and disabled shadow compilation.
Now, I compiled the original kernel code without any changes and it works like
a charm.
My next step is was to apply a path to the kernel. This mainly contains C-code
that seems to compile fine. There is however one exception. I have a single
line of assembler where I define a macro:
+#define MAGIC(n) do { \
+ __MAGIC_CASSERT((n) > 0 && (n) < (1U << 22)); \
+ asm ("sethi " #n ", %g0"); \
+} while (0)
This seem to be the cause of my problems. When I try to compile the kernel
again it now fails with the following output:
dmake: defaulting to parallel mode.
See the man page dmake(1) for more information on setting up the .dmakerc file.

According to my understanding, the asm statement is the one that causes the
error, but I might be wrong. I checked documentation on GCC style asm and my
statement seem to follow the convention. So, basically I'm currently out of
ideas.
Does anyone have some thoughts on this?
Regards,
Mladen
