hello, I am using Linux - Ubuntu, I downloaded Xerces-C++ 2.7.0
and Xalan-C++ 1.10.0 binaries, followed the instructions on the
website and managed to build both, I can run Xalan from the
command line - so this means that it built fine, doesn't it ?
If you downloaded the binaries, you don't need to build anything.
You only need to build if you download the source distributions.
However there is a problem if I want to compile some sample c++
code that uses Xalan. I followed the instructions on this website
: http://rudeserver.com/xalan/
I try to compile the test.cpp file from that site,this way :
g++ -o test -I /home/halski/parsery/xml-xalan/c/src/xalanc/ -I
/home/halski/parsery/xerces-c-src_2_7_0/include/
/home/halski/parsery/xerces-c-src_2_7_0/ test.cpp
/usr/lib/libxalan-c.so /usr/lib/libxerces-c.so
and I am getting this :
test.cpp: In function ‘int main()’:

Did you take a look at the sample programs? It's hard to say what
might be wrong since you didn't post any source code, but it's
probably an issue with C++ namespaces. If you look at one of the
sample programs, you will see lines of code like this:
XALAN_USING_XERCES(XMLPlatformUtils)
XALAN_USING_XALAN(XalanTransformer)
These are macros that wrap the C++ using directive, which brings a
name into the current scope. Alternately, you can do the following:
xercesc::XMLPlatformUtils::Initialize();
and:
xalanc::XalanTransformer::initialize();

Yep, sorry - of course I downloaded sources and built it - not binaries. The
file that gives me the above compilation errors is this :
#include <Include/PlatformDefinitions.hpp>
#include <util/PlatformUtils.hpp>
#include <XalanTransformer/XalanTransformer.hpp>
#include <iostream>
using namespace std;
int main(void)
{
XMLPlatformUtils::Initialize();
XalanTransformer::initialize();
XalanTransformer theXalanTransformer;
XSLTInputSource xmlIn("foo.xml");
XSLTInputSource xslIn("foo.xsl");
XSLTResultTarget xmlOut("foo-out.xml");
int theResult = theXalanTransformer.transform(xmlIn, xslIn, xmlOut);
cout << "Result of Transformation is " << theResult << "\n";
XalanTransformer::terminate();
XMLPlatformUtils::Terminate();
XalanTransformer::ICUCleanUp();
return 0;
}
So you clearly need the using directives, which will solve the compiler
errors.
After trying to compile some samples it seems to me that there is something wrong with the directory structure or include statements, eg. for xerces I have this option : -I /home/halski/parsery/xerces-c-src_2_7_0/include/
and I get an error :
XalanTransform.cpp:29:42: error: xercesc/util/PlatformUtils.hpp: No such file or directory
obvious - as there is no xercesc directory in /xerces-c-src_2_7_0/include/
Are you sure you set the XERCESCROOT environment variable correctly? if
the source directory is really "/xerces-c-src_2_7_0", then the
XERCESCROOT variable should be set to that string. Make sure you read
the Xerces-C build instructions carefully. My include directory has a
xercesc directory when my build completes.
