libvirt users - Jul 2014 - libvirt build issue - make check fails , file name long

Hi,
I was trying to build libvirt-0.10.2-29.

Now, it builds fine in simple directory setting:
like /home/itsme/test/libvirt/

But, if the directory setting is long:
like /home/public/test/abc-v1/liibvrt-v1-v2/   = > it fails.


Reason for failure is :qemumonitorjsontest

I tried running the specific test case like :
VIR_TEST_VERBOSE=1  ./qemumonitorjsontest

======================= 1) GetStatus
... libvir: XML-RPC error : Path
/home/public/abc_v1_v2/libvirt_0.10.2_29/BUILD/libvirt-0.10.2/tests/qemumonitorjsontest.sock
too long for unix socket: File name too long
FAILED
 2) GetVersion

 3) GetMachines

 4) GetCPUDefinitions

 5) GetCommands

FAILED
=======================Is this a known issue ?

Is there any specific patch which addresses this issue ? Please let me know.


Thanks,
Raj

That's a downstream port.  Which distro did you get it from? Have you
reported it to the distro?

Looks like that downstream port failed to include this upstream commit:

commit 0e7fd31fb52482903ebd34764c065867d26f93b5
Author: Guido Günther <agx@sigxcpu.org>

    Create temporary dir for socket

    to avoid ENAMETOOLONG:

Yes, and one fixed upstream.
