configure.ac - configure file issue

[abhsob]

I see the following issue when generating configure file. RHEL 6.5. Can these be ignored?

autoconf configure.ac > configure
configure.ac:8: error: possibly undefined macro: AM_INIT_AUTOMAKE
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:21: error: possibly undefined macro: AM_PROG_CC_C_O
configure.ac:25: error: possibly undefined macro: AC_MSG_ERROR
configure.ac:27: error: possibly undefined macro: AC_DEFINE_DIR
configure.ac:29: error: possibly undefined macro: LT_INIT
configure.ac:51: error: possibly undefined macro: AM_CONDITION

The configure file is generated so I tried to execute it. On running the configure see the following issue related to AM_INIT_AUTOMAKE

/configure: line 1819: syntax error near unexpected token foreign' ./configure: line 1819:AM_INIT_AUTOMAKE(foreign subdir-objects)'

[blp]

That's not how you invoke autoconf. Please use boot.sh.

[abhsob]

Thanks for the quick resolution.

I am running into another error:

configure: error: libopenvswitch.a was not found. Try --with-ovs-libpath

I searched for the file in the system but don't find it. I checked the
instructions for installation of openvswitch and I see that I have built it
as per the instructions. I used to openvswitch tarball install. Do I need
to do anything differently?

Thanks,
Abhijeet

Look at https://github.com/openvswitch/of-config/blob/master/INSTALL.md#open-vswitch-installation
You have to configure and make Open vSwitch. That is the place where OF-CONFIG's configure looks for all OVS stuff...
After successful build of OVS (make install is not necessary if you installed OVS in different way), configuration and build of OF-CONFIG can be done. https://github.com/openvswitch/of-config/blob/master/INSTALL.md#of-config-installation

[abhsob]

I already have openvswitch running:

ovs-vsctl show
760fdf5b-6eed-45b2-8573-5626dd978df1

Controller "tcp:x.x.x.x:6633" (modified to hide network IP)
Port "tap1"
Interface "tap1"
Port "br0"

Just to clarify, I did not build openvswitch from github sources but used
the tarball install. The

I was able to install and run ofc-server on RHEL 6.5 after following the
instructions on github. The only issue I had to resolve was in ovs-data.c.
I had to comment out
{ADVERTISED_40000baseKR4_Full, "40Gb"},
{ADVERTISED_40000baseCR4_Full, "40Gb"},
{ADVERTISED_40000baseSR4_Full, "40Gb"},
{ADVERTISED_40000baseLR4_Full, "40Gb"},

Looks like these are unsupported in RHEL6.5 env. If this is right then it
could be added to troubleshooting.

Thanks,
Abhijeet

Probably the correct solution would be to test for these constants and
define them if they are missing, e.g. as netdev-linux.c does for some
constants:

#ifndef ADVERTISED_Pause
#define ADVERTISED_Pause (1 << 13)
#endif

of-config search for it in the ovs-srcdir you set. Maybe it should have a better name or description, because it actually should be the "compiled source codes", not just the "source codes" I expect you have in /root/rpmbuild/SOURCES/openvswitch-2.3.1 - try to use /root/rpmbuild/BUILD/openvswitch-2.3.1instead.

hmm, I agree that we should test for these constants, but since we usethese constants when mapping rate from of-config data model from/to ioctl()'s ETHTOOL_GSET and ETHTOOL_SSET calls, we should probably ignore these values if they are not defined in system headers. Or do you think that the driver can define and use these rates on its own without support in the system headers, so we can get/set such values via ioctl()?

The machine on which the code builds is not necessarily the machine on
which the code runs. The headers with which the code builds are not
necessarily the exact headers for the machine on which the code runs.
Given those facts, you're better off defining any constants that are
likely to be missing, so that the code can handle the features on any
machine where it might run, even though it might build on a machine
whose headers lack those features.

Hi Radek,

I used the instructions in
http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=INSTALL.RHEL

using the distribution tarball. In that case, I don't see
the libopenvswitch.a anywhere on the system.

Then I deployed the openvswitch on another VM and did configure, make and
install as mentioned in the of-config install and then this file is found
in
./lib/libopenvswitch.a
./root/Downloads/openvswitch-2.3.1/lib/.libs/libopenvswitch.

Thanks,
Abhijeet

same as @abhsob on Ubuntu 16.10 and OVS 2.7 ..

checking for library containing ovsrec_init... no
configure: error: libopenvswitch.a was not found. Try --with-ovs-libpath

$ sudo find / -iname libopenvswitch.a -type f

any updates?

[Vivek788]

Even I am facing same problem with debian jessie and OVS 2.9.2. OF-config and OVS were taken from source.

If you are still getting "error: possibly undefined macro: LT_INIT" you need to install libtool.
