   [java] missing libaries in makefile
  I get the following error message, which seems to be a problem with the shared library I created. I am probably missing a library on the link line in the makefile, but can't see what it is.Exception in thread "main" java.lang.UnsatisfiedLinkError: /uufs/chpc.utah.edu/common/home/u0544384/Desktop/OpengL_Test/libMyWindow.so: /uufs/chpc.utah.edu/common/home/u0544384/Desktop/OpengL_Test/libMyWindow.so: undefined symbol: JAWT_GetAWTat java.lang.ClassLoader$NativeLibrary.load(Native Method)at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1803)at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1728)at java.lang.Runtime.loadLibrary0(Runtime.java:823)at java.lang.System.loadLibrary(System.java:1028)at MyWindow.<clinit>(MyWindow.java:14)Could not find the main class: MyWindow.
