Undefined reference error with methods of libxmlrpc-c3-dev

[Jaime Melis]

Binary package hint: gcc-4.5

I'm in a natty environment (created with pbuilder in an Ubuntu maverick).

# pbuilder create --distribution natty --othermirror "deb
http://archive.ubuntu.com/ubuntu natty main restricted universe
multiverse"

# pbuilder --login

Check g++ version:
# g++ --version|head -1
g++ (Ubuntu/Linaro 4.5.1-12ubuntu1) 4.5.2

I install required dependencies:
# apt-get install libxmlrpc-c3-dev libcurl4-openssl-dev

I create a small program which uses the xmlrpc-c library:
------------------------------------------------------------------------
server.cpp
------------------------------------------------------------------------
#include <xmlrpc-c/base.hpp>
#include <xmlrpc-c/registry.hpp>

int main(int argc, char *argv[])
{
    xmlrpc_c::registry RequestManagerRegistry;
    return 0;
}
------------------------------------------------------------------------

I obtain the building libraries with xmlrpc-config:
# xmlrpc-c-config c++2 abyss-server --libs --cflags
-L/usr/lib -lxmlrpc_server_abyss++ -lxmlrpc_server++
-lxmlrpc_server_abyss -lxmlrpc_server -lxmlrpc_abyss -lpthread
-lxmlrpc++ -lxmlrpc -lxmlrpc_util -lxmlrpc_xmlparse -lxmlrpc_xmltok
-I/usr/include

I compile the program:
# g++ server.cpp `xmlrpc-c-config c++2 abyss-server --libs --cflags`

collect2: ld returned 1 exit status

If we look for the missing references manually we can find them:
# nm -D /usr/lib/libxmlrpc++.so|grep trace
000000000000db80 T _ZN8xmlrpc_c3xml5traceERKSsS2_
                 U xmlrpc_traceXml

This used to work with previous versions of gcc:

(in the same environment)
# apt-get install g++-4.4

Check g++ version:
# g++-4.4 --version|head -1
g++-4.4 (Ubuntu/Linaro 4.4.5-10ubuntu1) 4.4.5

# g++-4.4 server.cpp `xmlrpc-c-config c++2 abyss-server --libs --cflags`
# echo $?
0

We need to fix this in order to complete the following merge:

Thank you

This is not a GCC bug, it's a result of the no-add-needed linker changes.

The following works for me:

$ g++ -o server server.cpp -lxmlrpc_server++ -lxmlrpc++ -lxmlrpc -lxmlrpc_xmlparse -lxmlrpc_xmltok -lxmlrpc_server

or, as a workaround:

$ g++ -o server server.cpp -Wl,--no-as-needed `xmlrpc-c-config c++2 abyss-server --libs`

[Matthias Klose (doko)]

the opennebula workaround needs to be reverted

[Dave Walker (davewalker)]

Is there still a task requirement for opennebula? This issue looks to be fixed, but I am reluctant to change it myself as I am in some doubt. Can those involved please comment and possibly set the task as appropriate?

Thanks.

[Damien Raude-Morvan (drazzib)]

This issue have been fixed by opennebula package 2.0.1-6 and xmlrpc-dev 1.16.33-1 (both in Debian unstable/wheezey).

[Damien Raude-Morvan (drazzib)]

 opennebula (2.0.1-6) unstable; urgency=low
 .
   * xmlrpc-c 1.16 transition:
     - d/control: Build-Depends on libxmlrpc-c++4-dev instead of
       libxmlrpc-c3-dev.
     - d/rules: Drop --no-as-needed from DEB_LDFLAGS_APPEND.
       LP: #690779.
   * d/copyright: Upgrade to latest DEP-5 format.
   * d/patches/ldflags_build.diff: Refreshed.
   * d/patches/linking.diff: Explicit linking with libxml2 (ie. reorder LIBS).
