The AGTEK Lib project contains native code for the TriMesh. In order to compile and test the library you must add a native “builder” to your Eclipse project. 
-  Import AGTEK_Lib into Eclipse (via SVN import) 
-  Open properties on AGTEK_Lib 
-  Click the resource “Builder” 
-  Click “New…” on the right side. 
-  Select “Program” as the configuration type. 
-  name the builder “NDK_Builder” 
-  Location - c:\cygwin\bin\bash.exe 
-  Working Directory - c:\cygwin\bin 
-  Arguments(for NDK r4):
 —-login -c “cd /cygdrive/c/<myapp_project_dir> && /cygdrive/c/Android_NDK/ndk-build”
 Substitute the string “myapp_project_dir” and the location of the Android NDK appropriately. Make sure you have the two hyphens before login and the quotes after the hyphen-c
 
-  Check “Refresh resources upon completion” 
-  Select “Specific resources” 
-  Click on the “Specify resources” button and select your project's lib directory. 
-  Check “Recursively include sub-folders” 
-  Now go to the build options tab 
-  Check “Allocate Console” 
-  Check “Launch in background” 
-  Check “Run the builder After a Clean” 
-  Check “Run the builder During manual builds” 
-  Check “Run the builder During auto builds” 
-  Check “Specify working set of relevant resources” 
-  Click on “Specify Resources” 
-  Select your project's JNI directory and all files within. 
-  Now click OK on the bottom. 
CAVEAT: When setting up paths, be aware that paths with spaces will cause issues. You may wish to use the 8.3 mangled name (e.g “MyDocu~1”) for path elements that need it.
Simple, eh? Have fun.
