hi,

I am trying to debug qemu with "--static" configuration but got the
following error message:

collect2: ld returned 1 exit status
make: *** [qemu-img] Error 1

It seems that in the Makefile it misses to link library pthread.

I modified Makefile and rebuild it without any problem.

ifdef CONFIG_STATIC
LDFLAGS+=-static
LIBS+=-lpthread
endif
ifdef BUILD_DOCS
DOCS=qemu-doc.html qemu-tech.html qemu.1 qemu-img.1
else
DOCS=
endif

Thanks,
Neo

I would remember that if researchers were not ambitious
probably today we haven't the technology we are using!
