Cannot compile simple programme that uses libxml++ because glibmmconfig.h not found

After stripping away all of the unnecessary code, this is the barebones version that refuses to compile:

#include <iostream>
#include <libxml++/libxml++.h>

using namespace std;

int main (int argc, char *argv[]) {
cout << "Hello, World!" << endl;
return 0;

I'm using an up-to-the-minute version of Fedora 16. Initially, the compiler could not find even libml++/libxml++.h, because Fedora's yum puts these files in /usr/include/libxml++-2.6/libxml++. So I got around that by creating the symlink /usr/include/libxml++ to /usr/include/libxml++-2.6/libxml++. That stopped the compiler from complaining about not finding libxml++.h, but then, in libxml++.h there is the line

#include <ustring.h>

which again the compiler could not find. So once again I created a symlink from /usr/include/glibmm to /usr/include/glibmm-2.4/glibmm, which is where ustring.h actually resides.

Now the compiler has stopped complaining about ustring.h, but the first (actual) line in ustring.h is

#include <glibmmconfig.h>

which the compiler cannot find.

The actual location of glibmmconfig.h is /usr/lib64/glibmm-2.4/include. But I would prefer not to alter ustring.h.

Is there a way out of my problems without constantly having to create symlinks, etc.?

Thanks in advance for your help.


I was able to get around my problems with the following compiler options:

`pkg-config --cflags --libs glibmm-2.4 libxml++-2.6`

Thanks to jpalecek for pointing the way, but I had to hunt some more until I was able to get around my problem.

But while these compiler options compile the simple programme above, they fail to compile the tutorial on the libxml++ tutorial page:

#include <iostream>
#include <libxml++/libxml++.h>
#include <string.h>

using namespace std;

int main (int argc, char *argv[]) {
string FilePath = "SampleXMLDocument.xml";
try {
xmlpp::DomParser Parser;
Parser.set_substitute_entities ();
Parser.parse_file (FilePath);
cout << "Successfully parsed XML file" << endl;
} catch (const exception& excp) {
cout << "Exception caught: " << excp.what () << endl;
return 0;
} // End main ()

I guess my search continues.
