Hi, ich brauch mal Hilfe beim Compilieren....
Wie haben uns mal nen NativeTreiber für Java geschnitzt, für MySQL.
Konnte ich vor einem Jahr noch compilieren, damals noch unter gcc2.9x, nun aber auf meiner Gentoo mit gcc3.2 knallts.
Leider hab ich mit C nicht genug am Hut dass ich sagen könnte was verkehrt läuft 
Kann mir einer weiterhelfen?
Hier der Code:
C

#include "de_commedia_mysql_NativeResultSet.h"

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <jni.h>
#include <time.h>
#include <math.h>
// #include <cruntime.h>
// #include <fltintrn.h>
#include <ctype.h>

const char *password = jEnv->GetStringUTFChars(jPassword, NULL);
// printf("using host %s and db %s and user %s and password %s\n", host, db, user, password);
MYSQL *mysql = mysql_init(NULL);
if (mysql != NULL) {
if (mysql_real_connect(mysql, host, user, password, db, 0, NULL, 0) == NULL) {

mysql = NULL;

Da wo SCHNIPP steht hab ich was rausgeschnitten, das scheint zu gehen.
Und hier der Fehler:
