How to build native libraries for Iotivity in order to load them in Java

I'm trying to run Iotivity Simple Clent in Java. I have cloned Iotivity project https://github.com/iotivity/iotivity and I have created an eclipse project that includes all the required Iotivity Java classes plus the classes for the SimpleClient from java-examples folder and I have no error so far.
When I try to run SimpleClient.java I get
Exception in thread "main" java.lang.UnsatisfiedLinkError: no ocstack-jni in java.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)
at org.iotivity.base.OcPlatform.<clinit>(OcPlatform.java:39)
at org.iotivity.base.examples.SimpleClient.startSimpleClient(SimpleClient.java:75)
at org.iotivity.base.examples.SimpleClient.main(SimpleClient.java:524)
I have installed SCONs and Gradle but I don't know how to proceed in order to build and create the "ocstack-jni" or any other library that is required to be loaded. My operating system is Windows 10.

You need to build with BUILD_JAVA=1 and the JAVA_HOME environment var must not be pointing to your current java install.

Crash in Dynamic Code Evolution VM

I am trying to run a Swing Client using Dynamic Code Evolution VM in IntelliJ using DCEVM integration plugin.When I start the app it crashes with following exception
Exception in thread "main" java.lang.UnsatisfiedLinkError: no freetype in java.library.path

I verified that SunFontManager is exist in rt.jar. Any idea?

DCEVM does not ship with fonts. So, when the JVM tries to load up the fonts, it doesn't find any and crashes. Fortunately, the fix is very easy. Simply copy the fonts from another JDK/JRE. You will find them at /jre/lib/fonts. Copy the entire directory to /lib.

7Zip-JBinding UnsatisfiedLinkError

I've looked through a number of the UnsatisfiedLinkError threads on here and nothing seems to quite fit my problem.
I am trying to get this api working: 7ZipBind
However I am having an issue, and cant get the thing to work. I am running some of its example code from the commandline like so:
C:>java -classpath
"/sevenzipTest.jar;/sevenzipjbinding-AllWindows.jar;\sevenzipjbinding.jar"
com.poc.sevenzip.SevenZipSimple c:\archive\test.zip
However when I try to run it I get the error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\Users\XXXX\AppData\Local\Temp\SevenZipJBinding-9640553\lib7-Zip-JBinding.dll: Can't

at com.poc.sevenzip.SevenZipSimple.runZip(SevenZipSimple.java:25)
at com.poc.sevenzip.SevenZipSimple.main(SevenZipSimple.java:64
What I am confused about, is why it says it cant locate the libraries (dll files), when the libraries are stored within the <file_path>/sevenzipjbinding-AllWindows.jar file... I am obviously not doing something correct here, and was hoping some1 can give me some pointers.
Cheers

The bug fix was released. Please, use version 1.06rc or above.
Download URL:
All versions
4.65-1.06rc-extr-only

The following instructions are for Windows x86 and 7 Zip JBinding version 4.65-1.05 RC. Download the following DLLs.
libstdc++-6.dll
libgcc_s_dw2-1.dll
gpsvc.dll
sysntfy.dll
Add the DLLs into the Windows-x86 directory in sevenzipjbinding-AllPlatforms.jar. Then append the following lines to sevenzipjbinding-lib.properties in the Windows-x86 directory in the jar.
sevenzipjbinding.libname.3=gpsvc.dll
sevenzipjbinding.libname.4=libgcc_s_dw2-1.dll
sevenzipjbinding.libname.5=libstdc++-6.dll
sevenzipjbinding.libname.6=sysntfy.dll
Instead of modifying the jar file, one could put the DLLs in the PATH (not classpath).
In order to figure this out, I extracted lib7-Zip-JBinding.dll from sevenzipjbinding-AllPlatforms.jar. I then opened the file in Dependency Walker.

Java - Library path error

I'm trying to start my java game but I have some troubles with the java command line:
Here is what I type:
C:\>java -Djava.library.path=%cd%\lib -jar game.jar
And here is what I got:

I can start my game with Eclipse (With Run as Java Application) but after the menu I got the following error:

lwjgl.jar has been put into the folder \lib.
Could you explain me with I got that?
Thanks.

This because lwjgl library is made by two components:
the .jar file which contains Java code
and the native binary library (which can be .so or .dll or .dylib according to your OS)
The first error you are getting is because you are setting the library path, that should contain the native library, but it does contain the .jar. So you get a java.lang.NoClassDefFoundError because you should set either the library path to the folder that contains native library, either the classpath to contain the real lwjgl.jar file.
The second error that you get with Eclipse is a successive step: your classpath contains the jar library but it is not able to find the native library attached to it, you can fix it in the following way:

You should specify explicitly which lib files to include (seperated by ;) :
-cp %cd%\lib\lwjdl.jar;%cd%\lib\<another-lib>.jar
Don't be tempted to use the wildcard * as it will cause more harm than good (from previous experience :))

You use the java.library.path option to specify the location of native libraries to load. In the location pointed to by that option you would place all dll or .so files required by LWJGL. On the other hand, you need to make sure that all required JAR files are on your classpath, via the -classpath option. Currently, you have your JAR files in the wrong directory.

In Eclipse, if you using maven.
Add the following to the project "Run" : "VM options" .
-Djava.library.path=yourpath/youproject/java/target/natives

How do I add external libraries to java.library.path in Eclipse?

My first time playing around with JOGL, and I get this:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path

I looked around and found nothing on how to add gluegen-rt or anything else to java.library.path.

See the answer at "How to set the java.library.path from Eclipse". Basically, there is a project configuration for "Native library location".
