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

Thank you in advanced.

Subject: [dpdk-dev] Undefined reference to FUSE

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.

Pablo
