Hello,

I have done what you said but it does not work.  I did it in the server
I usually use and in a VM, in both of them appears the error.
To be clear, I have followed the next instructions:

apt-get install fuse
apt-get install libfuse-dev
download dpdk-1.8.0
modify common_linuxapp:
+CONFIG_RTE_BUILD_COMBINE_LIBS=y
+CONFIG_RTE_LIBRTE_VHOST=y
make config T=x86_64-native-linuxapp-gcc
make install T=x86_64-native-linuxapp-gcc

git clone ovs
apply next patch:
http://openvswitch.org/pipermail/dev/2015-March/052061.html
./boot.sh
./configure --with-dpdk=$DPDK_BUILD
make

Is anything wrong with it?

I don't see anything obvious that's wrong. I've just checked it now on 
my own system with the commit I rebased against and it's compiling ok.
I'm on F20 with 3.16. The part of the patch that adds the fuse library 
is below, so you could check to make sure it has applied ok.

diff --git a/lib/automake.mk b/lib/automake.mk
index 2acfe18..594dec4 100644
--- a/lib/automake.mk
+++ b/lib/automake.mk

@@ -346,6 +346,7 @@ lib_libopenvswitch_la_SOURCES += \
 endif
 
 if DPDK_NETDEV
+lib_libopenvswitch_la_LDFLAGS += -lfuse

After that I'm not really sure where to go. I'll try it on the head of 
master when I'm back in the office on Wednesday. 

Thank you in advanced.

Regards,
Iñaki

Hello,

I have done a fresh install of dpdk-1.8.0 and ovs master brunch of
github with the next patches:

OVS: http://openvswitch.org/pipermail/dev/2015-March/052061.html
DPDK: http://dpdk.org/dev/patchwork/patch/2603/

Hi, can you try again except use tagged DPDK v1.8.0 without any patches to
it. Just turn COMBINE_LIB and VHOST_LIB settings to y. It might not be the
problem, but best to rule out as that's how we tested.

I rebased at the time to commit id 7cc398 on OVS master.

I still get the same error while compiling the ovs. I followed the same
instructions as I mentioned in passed emails.

Any suggestions?

Thank you in advanced.

Regards,

Iñaki

Hi Pablo,

Thank you very much, it worked for me.

But now I am trying to compile openvswicth after applying the next

patch:

http://openvswitch.org/pipermail/dev/2015-January/050278.html

And it happends the same. I gues that I should ask in the ovs mail list,
but in case you know the answer I ask here.

For ovs, if you use the head of master and the latest vhost patch, you
shouldn't see that error

Hello,

I am trying to compile the vhost example using DPDK 1.8.0. I have
installed fuse and libfuse-dev (as I am using Ubuntu). I have modified
config/common_linuxapp as follows:

CONFIG_RTE_BUILD_COMBINE_LIBS=y
CONFIG_RTE_LIBRTE_VHOST=y

Then, I compile DPDK 1.8.0 as follows:

make config T=x86_64-native-linuxapp-gcc
make install T=x86_64-native-linuxapp-gcc

And when it comes to compile vhost example I get errors about

undefined

reference. To compile it I use theses intructions:

export RTE_SDK=/path/to/dpdk-1.8.0
export RTE_TARGET=x86_64-native-linuxapp-gcc
make

The log of the error is:

Can anyone help me?

This was fixed after 1.8.0, on this patch:
http://dpdk.org/dev/patchwork/patch/2603/

You can either apply it yourself or get the latest code using git.
