hi - thanks all for the replies.
one interesting thing I've found out about a minute
ago is that:
the program runs perfectly fine if the single line
System.loadLibrary("myDll");
was changed to
System.loadLibrary("jpeg"); // this resolves to %JAVA_HOME%\jre\bin\jpeg.dll
(again: System.loadLibrary("myDll"); fails only if the
launched JVM is running under ant)
the JNI part of the source code actually looks like this:
--
#include <jni.h>
#include <stdio.h> // <- can this be problematic by any chance??
#include "foo_bar_baz.h"
JNIEXPORT jlong JNICALL
Jjava_foo_bar_baz_f(JNIEnv *env, jclass c) {
...
GetSystemInfo(&siSysInfo); //<- only operation (doesn't matter anyway)
...
return xyz;
}
--
now I'm thinking about dead-lock related to STDLIB
initialization routines (possibly coming from(?) <stdio.h>).
maybe try recompiling this particular DLL file with
different (compile and/or linking) options?
[this dll file actually is prepared by somebody else,
so at the moment I don't know exactly what was done to create this... anyway]
regards,
kenji
ps., so it looks like half-Ant-unrelated after all <sorry>.
ps2.,
- doing tests under ant1.5 didn't make any difference.
- below by the way is the complete build.xml file
