I tried to disable iasl without this patch and it worked for me...
I used:
- [Qemu-devel] [PATCH] configure: make --iasl option actually work
- ./configure --iasl="" (or --iasl=)
and it worked (no sign of IASL in config-host.mak)
I think this is because the prev test "$iasl -h > /dev/null 2>&1"
fails of course.
I don't get it how <test "$iasl"> helps if iasl is broken.
Thanks,
Marcel
