[dpdk-dev] Undefined reference to FUSE

[dpdk-dev] Undefined reference to FUSE

[IñakiMurillo]

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:

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.

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.

Thank you in advanced.

Iñaki

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

Re: [dpdk-dev] Undefined reference to FUSE

[IñakiMurillo]

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/

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, 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.

Re: [dpdk-dev] Undefined reference to FUSE

[IñakiMurillo]

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?

Thank you in advanced.

Regards,
Iñaki

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.

I can confirm this problem, at least on Ubuntu (14.10). I believe it is due to the fact that dependencies on shared objects (-lfuse) are not captured in .la files. Hence when executables are linked with libopenvswitch.a, the -lfuse link flag doesn't get added automatically.
I've seen this on another project but I'm not sure what is the proper solution. The difference with other shared objects (e.g. -ldl) is that those get added during configure step and land into $(LIBS) that then gets widely applied.

The easy workaround though is to add -lfuse to LIBS at ovs make invocation time:
 make LIBS=-lfuse
