Are there general guidlines for solving undefined reference/unresolved symbol issues?

I want to transform an xml to insert sql statements. I have ready the xml and xslt files and I know that transformation runs ok (tested with Oxygen).

Now, I’m coding this transformation with c++ unsuccessfully.

I have tried to include this libraries:

#include <libxml2/libxml/xmlversion.h>
#include <libxml2/libxml/parser.h>
#include <libxml2/libxml/valid.h>
#include <libxml2/libxml/xmlschemastypes.h>
#include <libxml2/libxml/xmlschemas.h>
#include <libxml2/libxml/xmlmemory.h>
#include <libxml2/libxml/debugXML.h>
#include <libxml2/libxml/HTMLtree.h>
#include <libxml2/libxml/xmlIO.h>
#include <libxml2/libxml/DOCBparser.h>
#include <libxml2/libxml/xinclude.h>
#include <libxml2/libxml/catalog.h>
#include <xalanc/Include/PlatformDefinitions.hpp>
#include <xercesc/util/PlatformUtils.hpp>
#include <xalanc/XalanTransformer/XalanTransformer.hpp>

but compiler show me a lot of errors in code like:

/home/kimpa2007/xml/src/main.cc:108: undefined reference to `xercesc_2_8::XMLUni::fgXercescDefaultLocale'

/home/kimpa2007/xml/src/main.cc:109: undefined reference to `xalanc_1_10::XalanTransformer::initialize(xercesc_2_8::MemoryManager&)'

Some one can explain how to code this transformation in a siple way?

    They are several ways to make XSL transformation, see Process an XML document using an XSLT stylesheet micro howto:

    • xsltproc
    • Xalan
    • SaxonB
    • Saxon6

    I see that you are intended to use Xalan. Perhaps this is actually the right way. Notice that this library needs to be configured. You can get help to configure it on Xayno90 post. I copy-paste here steps:

    I finally managed to compile and install Xerces and Xalan together for
    Ubuntu 10.04, do as follows:

    step 1

    sudo apt-get source libxerces-c28
sudo apt-get source libxalan110

    step 2.

    add "export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH" to /etc/ld.so.conf

    step 3.

    you may need to change owner of source packages from root to normal user

    step 4. Build Xerces

    export XERCESCROOT=/home/user/xerces-c2-2.8.0+deb1
cd $XERCESCROOT
cd src/xercesc
./runConfigure -plinux -cgcc -xg++ -minmem -nsocket -rpthread -b64 -P /usr/local
make
sudo XERCESCROOT=$XERCESCROOT make install

    step 5. Build Xalan

    export XERCESCROOT=/usr/local
cd $XERCESCROOT
/usr/local$ cd ~
export XERCESCROOT=/home/user/xerces-c2-2.8.0+deb1
cd $XERCESCROOT
cd ~
export XALANCROOT=/home/user/xalan-1.10/c
cd $XALANCROOT
./runConfigure -p linux -c gcc -x g++ -b64 -P /usr/local
make
sudo XALANCROOT=$XALANCROOT make install

    step 6.

    Check the directories of /usr/local/lib and /usr/local/include to confirm the both Xerces and Xalan are both installed

    The needs to be a wiki for a Ubuntu specific install of these XML libraries and packages as there is no definitive guide for this currently plus the install methods for other OS had to be interpreted in order to fit this installation.

    Also:

    Finally, read this SO posts:
