BridJ can't find the native library, no matter where it is

[Niko Vuokko]

Hiya,

I have a 64-bit DLL which was JNAerated into a BridJ Maven project and then made into a JAR. Then I have a Java project using this JAR as a Maven dependency, which I'm trying to run.

However, BridJ never finds the DLL. I've tried using a slim or the fat shaded JAR (with DLL under <jar>/lib/win64/), I've tried separately placing the DLL to ./, lib/win64/, src/main/resources/lib/win64 and some others as well, I've tried setting java.library.path to all these. These paths do show up in the BridJ logs with -Dbridj.debug  -Dbridj.veryVerbose and -Dbridj.logCalls, but the error remains. The DLL is 64-bit, Java is 64-bit, the DLL has no non-system dependencies.

Initially, before trying all these alternatives, the DLL at least showed up in AppData/Local/Temp/.../ along with bridj.dll, but now it doesn't anymore. Not sure why...

Any advice? I'm really out of ideas.


(Not sure if it's normal, the final log says:)

You should try

                System.setProperty("java.library.path", path);

        BridJ.addLibraryPath(path);

        BridJ.getNativeLibrary(libraryName);
