[xml] MinGW problem with xml2-config

[David Neary <David phenix fr>]

Hi all,

I'm having trouble getting a configure check to pass for libxml2. The test
program is compiling fine, and failing to link. This is with MinGW on Win32,
with libxml 2.5.11 compiled from source.

The program failing is this: 

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

int
main()
{
  int major, minor, micro;

  char *tmp_version;
  tmp_version = (char *)strdup("2.5.1");
  if (sscanf(tmp_version, "%d.%d.%d", &major, &minor, &micro) != 3) {
    printf("%s, bad version string from xml2-config\n", "2.5.1");
    exit(1);
  }
  free(tmp_version);


  LIBXML_TEST_VERSION

  /* Test that the library is greater than our minimum version */
  if ((2 > major) ||
      ((2 == major) && (5 > minor)) ||
      ((2 == major) && (5 == minor) &&
      (11 >= micro)))
  {
    return 0;
  }

  return 1;
}

The compilation command line is this:
gcc -o conftest.exe -g -O2 -Ic:/Dev-C++/include/libxml2   conftest.c
-Lc:/Dev-C++/lib -Lc:/Dev-C++/bin -lxml2 -lm

And finally, a small sample of the linker errors:

c:/Dev-C++/lib/libxml2.a(nanoftp.o): In function `xmlNanoFTPInit':
c:/src/libxml2-2.5.11/nanoftp.c:169: undefined reference to `WSAStartup 8'

c:/src/libxml2-2.5.11/nanoftp.c:997: undefined reference to `send 16'

There are several more like that - all in nanoftp and nanohttp.

Anyone know what I can do to get this passing? Is the solution to be done
with it and use pkg-config? The goal is to compile libxmlj for win32...

Thanks,
Dave.
