[Qemu-devel] build problems with linux usb support?

[Troy Benjegerdes]

I'm trying to build qemu from cvs on a Debian-amd64 system, and having
errors like this:

gcc-3.4 -Wall -O2 -g -fno-strict-aliasing -I.
-I/afs/scl.ameslab.gov/user/troy/src/qemu-cvs/target-i386

/usr/include/asm-generic/div64.h:54:3: #error do_div() does not yet
support the C64


The only think I can track down so far is that BITS_PER_LONG is only
defined in /usr/include/asm-x86_64/types.h if __KERNEL__ is also set.

What other linux distros/headers work with the current qemu cvs usb
code?

Thanks.

You really try to make QEmu run on a C64? Wow!

;-) Sorry, could not resist,

I've just been disabling USB support by a local patch and hoping
someone else fixed this :-)

Would you mind posting the 'disable usb' patch?

Right now I am resorting to gross things like building on a redhat box
and installing the binaries on debian.
