I didn’t mention it but im building qemu out of the source tree(running the
configure in a different directory).
I tried to find the missing dependency but no luck.
The build error keeps happening Here is the end of the log(please note that I
don’t see here "CC trace/generated-events.o"):.

In qemu.git/master:Makefile I see:
ifeq ($(CONFIG_SMARTCARD_NSS),y)
include $(SRC_PATH)/libcacard/Makefile
endif
That doesn't look like recursive make to me, but maybe I'm missing
something.

hi,
im building qemu with a large make -j value(9).
sometimes the build fails because of an error:

i see the build of generated-events.o in the log before the ar command.
because of the -j it was probably not completed yet.

trace/generated-events.c
must be a race condition in the makefile because of a missing dependency.
i tried to find it but it was a little bit complicated to me.
thanks,
