**THIS PAGE IS OBSOLETE, MODERN NDK BUILD IS DONE IN ANDROID STUDIO.** The AGTEK Lib project contains native code for the TriMesh.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. The following instructions are from this web site: http://www.rbgrn.net/content/348-get-your-eclipse-integrated-ndk-on Here is what you need to do - 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/ && /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.
