Question

I have installed Netbeans 7.1.1 connecting to a remote build host (my virtual box).
I tried to compile some program I found on certain website.

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <libxml/tree.h>
#include <libxml/parser.h>
#include <libxml/parserInternals.h>

// Appelée à la rencontre de chaque balise ouvrante
void debut_element(void *user_data, const xmlChar *name, const xmlChar **attrs) {
printf("Début de l'élément : %s\n", name);
}

int main() {
// Initialisation à zéro de tous les membres (NULL pour un pointeur par conversion)
xmlSAXHandler sh = { 0 };

// Affectation des fonctions de rappel
sh.startElement = debut_element;

xmlParserCtxtPtr ctxt;
// Création du contexte
if ((ctxt = xmlCreateFileParserCtxt("catalogue.xml")) == NULL) {
    fprintf(stderr, "Erreur lors de la création du contexte\n");
    return EXIT_FAILURE;
}
// Fonctions de rappel à utiliser
ctxt->sax = &sh;
// Analyse
xmlParseDocument(ctxt);
// Le document est-il bien formé ?
if (ctxt->wellFormed) {
    printf("Document XML bien formé\n");
} else {
    fprintf(stderr, "Document XML mal formé\n");
    xmlFreeParserCtxt(ctxt);
    return EXIT_FAILURE;
}
// Libération de la mémoire
xmlFreeParserCtxt(ctxt);

return EXIT_SUCCESS;
}

However, I got this error message during compilation

I know this has been asked thousands of times here but I couldn’t find the correct answer.
Appreciate if anyone of you could guide me as I am new in this.

Answer 1

I don’t know how to configure Netbeans; but your code compiles without trouble if you execute this command by hand:

gcc -o xmltest xmltest.c -I /usr/include/libxml2 -lxml2

If you don’t yet have a Makefile, this is a good start:

LDFLAGS := -I /usr/include/libxml2 -lxml2

But, if Netbeans forces you to use a different build system, you’ll have to figure out another way to set the linker options appropriately.
