I've found that the the change comes in release 1.36.0. I'll update the
static xmlrpc library that we use to generate packages for the next release
with 1.40.0, that is the latest stable release.
Right now the only distribution packages that use the stock xmlrpc-c
library are CentOS 7. It comes with version 1.32.5 so I suppose I'll have
to link them statically.
Concerning manual compilation. While the new release is not ready you can
compile OpenNebula linking statically with the new library and only
substitute oned binary. That should be in src/Nebula directory after
compiling. You should be able to upgrade normally with this method. These
are the steps we use to compile OpenNebula:
--8<------
svn checkout http://svn.code.sf.net/p/xmlrpc-c/code/release_number/01.40.00
cd 01.40.00
export CXXFLAGS="-fPIC"
export CFLAGS="-Wno-error=format-security"
./configure --prefix=$PWD/install --enable-libxml2-backend
make install
# Delete dynamic libraries
rm -f install/{lib,lib64}/*.so install/{lib,lib64}/*.so.*
# Add xmlrpc-c libraries bin dir to the path
export PATH=$PWD/install/bin:$PATH
export XMLRPC=$PWD/install
cd <opennebula source code>
scons -j2 mysql=yes xmlrpc=$XMLRPC new_xmlrpc=yes syslog=yes
------>8--
Cheers
