Hi All,

The joys of working with a cutting edge distro on my workstation ...

[Qemu-devel] [PATCH 1/2] device_tree: Fix build with latest libfdt

[Hans de Goede]

We override libfdt_env.h with our own copy, and the latest libfdt expects
libfdt_env.h to define fdt##_t types.

[Qemu-devel] [PATCH 2/2] usb/host-libusb: Fix building with libusb git master code

[Hans de Goede]

The next libusb release will deprecate libusb_get_port_path, and since
we compile with -Werror, this breaks the build.

Looks sane to me, but I'll leave that to the fdt experts ...

cheers,

I just added libusb_get_port_numbers to FreeBSD's libusb, but we don't
have LIBUSBX_API_VERSION defined; we don't (yet) implement all of the
functionality that would be implied by given version.

I'm not sure if it'd be better to add the definition in FreeBSD's
libusb (and fault in missing functionality as needed, presumably), or
address it in libusb consumers with additional #ifdefs.

This discussion is open on list, and AFAICT the consensus is to drop
qemus libfdt_env.h altogether. QEMU should not be trying to override
libfdt_env.h because it does not have a good reason to.

[PATCH v2 1/1] configure: dtc: Probe for libfdt_env.h

CCing the crowd.

Peter

F19, F20 and EPEL6 will all distribute libfdt_env.h by the time 1.6 is
out.  If this patch is not qemu-stable material, you have my ack too.
Thanks!

For clarity, by "this patch" do you mean the one that started
this email thread (from Hans) or the one from Peter that he
quotes the Subject of here?

thanks

The one that requires libfdt_env.h to be installed under /usr/include.
