Hi,

I tried too, to get openvswitch datapath module compile with 3.1-rc6 kernel, but with no luck. Seems skipping the hh calls in tunnel.c won't do it, it then complains about something else :/

-> Back to 3.0  :)

I'm guessing because they're going to remove the "hh" member from the 
"dst_entry" struct in Linux 3.1.  ;-)  I imagine shortly after 3.1 is released, we'll 
make the version in git work with it.  In the meantime, you're better off using Linux 3.0 unless 
you want to modify the OVS source yourself.  If you don't care about tunneling, you may be able to 
just comment out the offending lines, but of course you may run into other problems.

Good luck!

Ah! Thanks, Justin!

I reran "./boot.sh" (after a make distclean) and that got me past the configure 
errors. Since I'm compiling OVS for kernel v3.1.0, I made a small change in 
datapath/linux/datapath.c -- changed line 57 to:
"LINUX_VERSION_CODE>  KERNEL_VERSION(3,1,0)"

Now "make" gives me the following errors:

Any suggestions on how to fix this?

I assume you're doing this from git, right?  Have you run "./boot.sh" lately?

I tried compiling on kernel 3.1.0-rc4:
./configure --with-linux=/usr/src/linux-headers-`uname -r`

I got the following error:
configure: creating ./config.status
config.status: creating Makefile
config.status: creating datapath/Makefile
config.status: error: cannot find input file: `datapath/linux-2.6/Kbuild.in'


Am I doing something wrong?

Both of these changes have been available since the 1.2.0 release of Open

Hi Ben,

Where can I find the patches?

Thanks,

I think a proper fix would be to rename the '--with-l26' configure option to
'--with-linux' and change the configure-time kernel version check to allow
2.6.x or 3.x.
I sent out patches for this.
