- The default is a fuller feature set at a larger size.
- NOTE: This option does not prevent you from overriding the default

- Build natively in a CMD.exe environment with Windows style paths
- (like C:\cygwin\home)
- The Windows native build is complete and available, but not often
- used or verified. As a consequence, it cannot be assured to be
- fully functional at any given time. Hence, it is marked here as

- ---help---
- Use the mklink command to set up symbolic links when NuttX is
- configured. Otherwise, configuration directories will be copied to
- establish the configuration.
- If directories are copied, then some confusion can result ("Which
- version of the file did I modify?"). In that case, it is recommended
- that you re-build using 'make clean_context all'. That will cause the
- configured directories to be recopied on each build.
- NOTE: This option also (1) that you have administrator privileges, (2)
- that you are using Windows 2000 or better, and (3) that you are using
- the NTFS file system. Select 'n' is that is not the case.
- menu "Build Configuration"
- config APPS_DIR
- string "Application directory"
- default "../apps" if !WINDOWS_NATIVE
- default "..\apps" if WINDOWS_NATIVE
- ---help---
- Identifies the directory that builds the
- application to link with NuttX. Default: ../apps This symbol must
- be assigned to the path to the application build directory
- *relative* to the NuttX top build directory. If you had an
- application directory and the NuttX directory each in separate
- directory trees like this:
- build
- |-nuttx
- | |
- | `- Makefile
- `-application
- |
- `- Makefile
- Then you would set APPS_DIR=../application.
- The application direction must contain Makefile and this make
- file must support the following targets:
- 1)libapps$(LIBEXT) (usually libapps.a). libapps.a is a static
- library ( an archive) that contains all of application object
- files.
- 2)clean. Do whatever is appropriate to clean the application
- directories for a fresh build.
- 3)distclean. Clean everything -- auto-generated files, symbolic
- links etc. -- so that the directory contents are the same as
- the contents in your configuration management system.
- This is only done when you change the NuttX configuration.
- 4)depend. Make or update the application build dependencies.
- When this application is invoked it will receive the setting TOPDIR like:
- $(MAKE) -C $(CONFIG_APPS_DIR) TOPDIR="$(TOPDIR)" <target>
- TOPDIR is the full path to the NuttX directory. It can be used, for
- example, to include makefile fragments (e.g., .config or Make.defs)
- or to set up include file paths.
- config BUILD_LOADABLE
- bool
- option modules
- ---help---
- Automatically selected if KERNEL build is selected.

- depends on ARCH_USE_MPU
- select LIB_SYSCALL
- select BUILD_2PASS
- ---help---
- Builds NuttX and selected applications as two "blobs": A protected,
- privileged kernel blob and a separate unprivileged, user blob. This
- requires use of the two pass build with each blob being build on
- each pass.
- NOTE: This build configuration requires that the platform support
- a memory protection unit (MPU). Support, however, may not be
- implemented on all platforms.
- config BUILD_KERNEL
- bool "NuttX kernel build"
- depends on ARCH_USE_MMU && ARCH_ADDRENV
- select BUILD_LOADABLE
- select LIB_SYSCALL
- ---help---
- Builds NuttX as a separately compiled kernel. No applications are
- built. All user applications must reside in a file system where
- they can be loaded into memory for execution.
