我有一个libxml2的简单示例,但它返回以下错误:
$ gcc -Wall -lxml2 -I/usr/include/libxml2 -o ex1 ex1.c
/tmp/cc6OKSKJ.o: In function `main':
ex1.c:(.text+0x60): undefined reference to `xmlReadFile'
ex1.c:(.text+0x70): undefined reference to `xmlDocGetRootElement'
collect2: ld returned 1 exit status
$ xml2-config --libs
-lxml2
$ xml2-config --cflags
-I/usr/include/libxml2
我在Lubuntu 11.10 x86_64上,我有我需要的所有软件包(我认为):libxml2,libxml2-dev,libxml2-dbg ...这是示例的代码:
// gcc -Wall -lxml2 -I/usr/include/libxml2 -o ex1 ex1.c
#include <stdio.h>
#include <string.h>
#include <libxml/parser.h>
int main(int argc, char **argv)
{
xmlDoc *document;
xmlNode *root, *first_child, *node;
char *filename;
if (argc < 2)
{
fprintf(stderr, "Usage: %s filename.xml\n", argv[0]);
return 1;
}
filename = argv[1];
document = xmlReadFile(filename, NULL, 0);
root = xmlDocGetRootElement(document);
fprintf(stdout, "Root is <%s> (%i)\n", root->name, root->type);
first_child = root->children;
for (node = first_child; node; node = node->next)
{
fprintf(stdout, "\t Child is <%s> (%i)\n", node->name, node->type);
}
fprintf(stdout, "...\n");
return 0;
}
