Create the audio object as described above<\/p>\n

Build the library for the audio object and create corresponding header file for the audio object library to expose the functions. An example of a header file can be found under external\/inc\/Template.h<\/p>\n

The object header file name should be similar to the audio object class name. For example if the audio object class name is CTemplate, the header file name should be Template.h<\/p>\n

Create a header file which contains object Ids for all the audio objects you want to create.<\/p>\n

Example object Id should be similar to Figure below. Also find the same file under \/external\/inc\/AudioIds.h<\/p>\n

\"\"<\/p>\n

Name of the pre-processor definition should be OBJ_\u201cheader file name\u201c. For example if the name of the class is CDcBlocker, then the header file name should be DcBlocker.h and pre-processor definition in AudioIds.h should be #define OBJ_DCBLOCKER 1005<\/p>\n

Create a cmake configuration as shown in Figure 17-2and set the following variables<\/p>\n

EXTERNAL_OBJECT_INCLUDE:<\/span> Specify the folders which contains the audio object header files created.<\/p>\n

EXTERNAL_OBJECT_LIB :<\/span> Specify audio object libraries.<\/p>\n

OBJECT_ID_PATH:<\/span> Specify object ID file.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

Navigate to external\/ folder<\/p>\n

Type cmake.exe” . -DTARGET_ARCH=WIN32 -DCMAKE_BUILD_TYPE=Release -DEXTERNAL_OBJECT_CONFIG =”C:\/Object_config.cmake”
\nNote: Assuming Object_config.cmake is under C:\/<\/p>\n

This will generate the xAFLibraries.sln under external\/ folder<\/p>\n

Open the solution file with administrator privilege and build the visual studio project<\/p>\n

This will produce the xAF Libraries under public\/lib\/win32\/Debug folder if built for Debug mode
\nand public\/lib\/win32\/Release folder if built for Release mode<\/p>\n

The generated libraries will contain the newly created audio object(s)<\/p>\n

If user has a MSVC project to build the object library, it can be added to the xAFLibraries.sln for debugging purposes.<\/p>\n

Example #1 (Building with cmake on Summit)<\/h4>\n

Navigate to <car_audio_repo>\/customer\/reference\/xaf_reference_app\/c66_app folder and below files are present<\/p>\n
