4.3.3 Application Configuration File

- -

- The appconfig File. - A special configuration file is used to configure which applications are to be included in the build. - The source for this file is saved at configs/<board>/<configuration>/appconfig. - The existence of the appconfig file in the board configuration directory is sufficient to enable building of applications. -

- The appconfig file is copied into the apps/ directory as .config when NuttX is configured. - .config is included by the top-level apps/Makefile. - As a minimum, this configuration file must define files to add to the CONFIGURED_APPS list like: -

- Changes in the Works. - There are changes in the works that will obsolete the appconfig file. - These changes will implement an automated configuration system for NuttX. - One consequence of this new configuration system is that the appconfig file will become obsolete and will be replaced by a new mechanism for selecting applications. - This new mechanism is not yet available, but is dicussed here: http://tech.groups.yahoo.com/group/nuttx/message/1604. -

+
+  If you run 'make menuconfig' with a legacy configuration the resulting

   Q: How can I tell if a configuration is a new kconfig-frontends
      configuration or an older, manual configuration?
 
-  A: a) New kcondfig-frontends configurations will have this setting
-        within the defconfig/.config file":
+  A: Only old, manual configurations will have an appconfig file

-
-Converting Older Configurations to use the Configuration Tool
--------------------------------------------------------------
 
   Q: How can I convert a older, manual configuration into a new,
      kconfig-frontends toolchain.
 
-  A: 1) Look at the appconfig file:  Each application path there
-        will now have to have an enabling setting.  For example,
-        if the old appconfig file had:
-
-          CONFIGURED_APPS = examples/ostest
-
-        Then the new configuration will need:
-
-          CONFIG_EXAMPLES_OSTEST=y
-
-        The appconfig file can then be deleted because it will not
-        be needed after the conversion.
-
-     2) Build the cmpconfig utility at tools:
-
-          cd tools
-          make -f Makefile.host cmpconfig
-
-     3) Perform these steps repeatedly until you are convinced that
-        the configurations are the same:
-
-        a) Repeat the following until you have account for all of the differences:
-
-             cp configs///defconfig .config
-             make menuconfig  (Just exit and save the new .config file)
-             tools/cmpconfig configs///defconfig .config | grep file1
-
-           The final grep will show settings in the old defconfig file that
-           do not appear in the new .config file (or have a different value
-           in the new .config file).  In the new configuration, you will
-           probably have to enable certain groups of features.  Such
-           hierarachical enabling options were not part of the older
-           configuration.
-
-        b) Then make sure these all make sense:
-
-             tools/cmpconfig configs///defconfig .config | grep file2
-
-           The final grep will show settings in the new .config file that
-           do not appear in the older defconfig file (or have a different value
-           in the new .config file).  Here you should see only the new
-           hierarachical enabling options (such as CONFIG_SPI or CONFIG_MMCSD)
-           plus some other internal configuration settings (like CONFIG_ARCH_HAVE_UART0).
-           You will have to convince yourself that these new settings all make sense.
-
-     4) Finally, update the configuration:
-
-          cp .config configs///defconfig
-          rm configs///appconfig
-
-        NOTE:  You should comment out the line containing the CONFIG_APPS_DIR
-        in the new defconfig file.  Why?  Because the application directory
-        may reside at a different location when the configuration is installed
-        at some later time.
-
-          # CONFIG_APPS_DIR="../apps"
-
-     5) The updated configuration can then be instantiated in the normal
-        fashion:
-
-          cd tools
-          ./configure.sh /
-
-        (or configure.bat for the case of the Windows native build).
-
-        NOTE: If CONFIG_APPS_DIR is not defined in the defconfig file,
-        the configure.sh script will find and add the new, correct path to
-        the application directory (CONFIG_APPS_DIR) when it copies the
-        defconfig file to the .config file.  This is the setting that was
-        commented out in step 4.
