Then the bug is not in qemu, but in your environment. Installing known-broken heirloom where it can be found first on a PATH search for sh is just asking for problems, not just with qemu, but with all SORTS of programs that expect POSIX semantics from a Linux /bin/sh. Rather than change the Makefile to invoke the script with bash, we could instead bend over backwards to rewrite the script in a way that works with non-POSIX shells (as in, flag=`expr $flag ^ 1`), but that feels backwards to me. Until someone is actively worried about porting qemu to a true Solaris environment, rather than just an heirloom-as-/bin/sh Linux environment, I don't think it's worth the effort. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
