Merged in masayuki2009/nuttx.apps/loadable_app (pull request #148) loadable app support * apps: Introduce a build system for loadable apps for nsh. This PR consits of following changes. (NOTE: Changes to each application will be provided separately) apps/nshlib/Kconfig: Add 'option modules' to NSH_FILE_APPS so that a user can change an application configuration to tristate (y/n/m) apps/Make.defs: Override COMPILE and COMPILEXX macros to compile loadable apps. To make loadable apps, -DLOADABLE_APP is added to the flags. Also, introduce ELFLD to link a lodable app. Please note that the variable 'LOADABLE' must be defined in each application Makefile if you want to make a loadable app. apps/Application.mk: Add .build target in case of 'LOADABLE=y' which is used to link a final loadable application and install the app to apps/bin. apps/Makefile: Add SYMTABSRC and SYMTABOBJ variables for loadable apps which will be generated under the apps directory. Add make_symbols target which will be called when all applications are installed to generate symtab_app.c which is used for nsh to inform symbol information to the NuttX kernel. Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com> * apps/examples/hello: Apply changes to support a lodable app. Kconfig: Change the application state from bool to tristate Make.defs: Change the condition to build. By default, the application is not selected (i.e. 'n'), so if other states (i.e. y/m) are selected, the application will be compiled. Makefile: If the application is specified to 'm', the variable 'LOADABLE' must be defined here. Also note that other variables (PRIORITY and STACKSIZE) can only be used for built-in apps. hello_main.c Add LOADABLE_APP condition to main().

By default, if CONFIG_HAVE_CXX and CONFIG_HAVE_CXXINITIALIZE are
|
|
defined, then this example will call the NuttX function to
|
|
initialize static C++ constructors. This option may be disabled,
|
|
however, if that static initialization was performed elsewhere.
