[platform-swt-dev] Build Custom JNI Functions in SWT
|
Hi All,
I am attempting to make a custom JNI function that integrates with swt - I modified OS.java and OS_Custom.c (See code below). After I run build.xml (which says "BUILD SUCCESSFUL") I attempt to call my new function but get the following error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.eclipse.swt.internal.win32.OS.newFunction()[I
Am I missing something to be able to write my own custom function? Is there a good example of being able to do so? It seems as though after 3 days of searching that there wouldn't be an answer, but I hope I'm close. Thanks.
Josh
OS.java Added:
/** @method flags=no_gen */
private static final native int[] newFunction();
OS_Custom.c Added:
#ifndef NO_newFunction
JNIEXPORT jintArray JNICALL OS_NATIVE(newFunction)
(JNIEnv *env, jclass that)
{
jintArray iarr = (*env)->NewIntArray(env, 256); //just to test
int i;
if (iarr == NULL)
{
return NULL; /* out of memory error thrown */
}
jint tmp[256];
for (i = 0; i < 256; i++)
{
tmp[i] = i + 100;
}
(*env)->SetIntArrayRegion(env, iarr, 0, 256, tmp);
return iarr;
}
#endif
