  44. <p>This article describes the start of MJIN library separation into modules.</p>
  45. <p>Once we built OpenSceneGraph for Android, it became obvious that some MJIN functionality is not suitable for Android. For example, UIQt provides a basis for OGS Editor UI. Since OGS Editor is a desktop application, we don't need UIQt for Android.</p>
  46. <p>We decided to have a look at two approaches to separate MJIN into modules: build-time separation and run-time one.
  47. <strong>Build-time</strong> separation means MJIN becomes highly configurable and each platform gets specifically tailored MJIN build.
  48. <strong>Run-time</strong> separation means MJIN is divided into smaller libraries that are connected at run-time, which makes it easy to change functionality without rebuilding.</p>
  49. <p><strong>Run-time separation research.</strong></p>
  50. <p>Since run-time separation has more benefits, we started researching it first.
  51. The easiest way to achieve it was to use C API, because C ABI rules are much simpler than C++ one's.</p>
  52. <p>We created a sample project consisting of the application, library, and plugin.
  53. <strong>The application</strong> has been linked to the library and used it to load the plugin.
  54. <strong>The library</strong> provided functions to register plugins and call their functions.
  55. <strong>The plugin</strong> provided functions for the library and called library functions.</p>
  56. <p>The research was successful: the sample project worked correctly under Linux and Windows. However, since MJIN is currently a single large entity, we postponed C API application until we finish build-time separation.</p>
  57. <p><strong>Build-time separation start.</strong></p>
  58. <p>We extracted the following modules from MJIN:</p>
  59. <ul>
  60. <li>
  61. <p>Android: provides Java Native Interface (JNI) to MJIN</p>
  62. </li>
  63. <li>
  64. <p>Sound: provides access to OpenAL</p>
  65. </li>
  66. <li>
  67. <p>UIQt: provides access to Qt UI</p>
  68. </li>
  69. </ul>
  70. <p>Sound and UIQt modules are currently statically linked into MJIN library, while Android module is already a separate library due to JNI requirements.</p>
  71. <p>In the coming year, we're going to significantly restructure MJIN so that it suits as many platforms as possible.</p>
  72. <p>That's it for describing the start of MJIN library separation into modules.</p>
