Compile problem when using JNI in c program.

Question

I am run JDK 1.4 on AIX 5.1. I am trying to compile following code.
#include <jni.h>
main() {
JNIEnv *env;
JavaVM *jvm;
JDK1_1InitArgs vm_args;
jint res;
jclass cls;
jmethodID mid;
jstring jstr;
jobjectArray args;
/* IMPORTANT: specify vm_args version # if you use JDK1.1.2 and beyond */
vm_args.version = 0x00010001;
JNI_GetDefaultJavaVMInitArgs(&vm_args);
res = JNI_CreateJavaVM(&jvm,&env,&vm_args);
if (res < 0) {
fprintf(stderr, "Can't create Java VM\n");
exit(1);
cls = (*env)->FindClass(env, "Prog");
if (cls == 0) {
fprintf(stderr, "Can't find Prog class\n");
exit(1);
mid = (*env)->GetStaticMethodID(env, cls, "main", "([Ljava/lang/String;)V");
if (mid == 0) {
fprintf(stderr, "Can't find Prog.main\n");
exit(1);
jstr = (*env)->NewStringUTF(env, " from C!");
if (jstr == 0) {
fprintf(stderr, "Out of memory\n");
exit(1);
args = (*env)->NewObjectArray(env, 1,
(*env)->FindClass(env, "java/lang/String"), jstr);
if (args == 0) {
fprintf(stderr, "Out of memory\n");
exit(1);
(*env)->CallStaticVoidMethod(env, cls, mid, args);
(*jvm)->DestroyJavaVM(jvm);
I run this command command and get the following errors
gcc invoke.c -o invoke -I/usr/java14/include -I/usr/java14/jre/bin -L/usr/java14/jre/bin -Lusr/java14/jre/bin/classic/
ld: 0711-317 ERROR: Undefined symbol: .JNI_GetDefaultJavaVMInitArgs
ld: 0711-317 ERROR: Undefined symbol: .JNI_CreateJavaVM
I think I having all the location for the correct libraries or am I missing one.

You must include the aix sub-folder and the main include folder:
-I/usr/java14/include/aix -I/usr/java14/include
(No need to include the bin folder)
