---help---
When options are present, the default value for certain options will
be the one the results in the smallest size (at a loss of featurs).
The default is a fuller feature set at a larger size.
NOTE: This option does not prevent you from overriding the default
to select another alternative. Nor does it affect the settings that
have already been selected in your configuration file. This applies
only to new settings that require a default value.

endchoice
config WINDOWS_MKLINK
bool "Use mklink"
default n
depends on WINDOWS_NATIVE
---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.
choice
prompt "Memory organization"
default BUILD_FLAT
config BUILD_FLAT
bool "Flat address space"
---help---
Build NuttX as one large, executable "blob". All of the code
within the blob can interrupt with all of the other code within
the blob. There are no special privileges, protections, or
restraints.
config BUILD_PROTECTED
bool "NuttX protected build"
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 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.
NOTE: This build configuration requires that the platform support
a memory management unit (MPU) and address environments. Support,
however, may not be implemented on all platforms.
endchoice # Build configuration
config BUILD_2PASS
bool "Two pass build"
default n
depends on !BUILD_KERNEL
---help---
Enables the two pass build options.
Two-pass build options. If the 2 pass build option is selected, then these
options configure the make system build a extra link object. This link object
is assumed to be an incremental (relative) link object, but could be a static
library (archive) (some modification to this Makefile would be required if
PASS1_TARGET generates an archive). Pass 1 1ncremental (relative) link
objects should be put into the processor-specific source directory (where other
link objects will be created). If the pass1 object is an archive, it could
go anywhere.
if BUILD_2PASS
config PASS1_TARGET
string "Pass one target"
default "all"
---help---
The name of the first pass build target. This
can be specific build target, a special build target (all, default, etc.)
or may just be left undefined.
config PASS1_BUILDIR
string "Pass one build directory"
default "build"
---help---
The path, relative to the top NuttX build
directory to directory that contains the Makefile to build the
first pass object. The Makefile must support the following targets:
The special target PASS1_TARGET (if defined)
and the usual depend, clean, and distclean targets.
config PASS1_OBJECT
string "Pass one object"
default ""
---help---
May be used to include an extra, pass1 object
into the final link. This would probably be the object generated
from the PASS1_TARGET. It may be available at link time
in the arch/<architecture>/src directory.
config NUTTX_USERSPACE
hex "Beginning of user-space blob"
default 0x0
depends on BUILD_PROTECTED
---help---
In the kernel build, the NuttX kernel and the user-space blob are
built separately linked objects. NUTTX_USERSPACE provides the
address where the user-space blob is loaded into memory. NuttX will
expect to find and instance of struct userspace_s at this location.

bool "Intel HEX binary format"
default n

config ARCH_STDINT_H
bool "stdint.h"
default n
---help---
The stdint.h header file can be found at nuttx/include/stdint.h.
However, that header includes logic to redirect the inclusion of an
architecture specific header file like:
#ifdef CONFIG_ARCH_STDINT_H
# include <arch/stdint.h>
#else
...
#endif
Recall that that include path, include/arch, is a symbolic link and
will refer to a version of stdint.h at nuttx/arch/<architecture>/include/stdint.h.
config ARCH_STDBOOL_H
bool "stdbool.h"
default n
---help---
The stdbool.h header file can be found at nuttx/include/stdbool.h.
However, that header includes logic to redirect the inclusion of an
architecture specific header file like:
#ifdef CONFIG_ARCH_STDBOOL_H
# include <arch/stdbool.h>
#else
...
#endif
Recall that that include path, include/arch, is a symbolic link and
will refer to a version of stdbool.h at nuttx/arch/<architecture>/include/stdbool.h.
config ARCH_MATH_H
bool "math.h"
default n
---help---
There is also a re-directing version of math.h in the source tree.
However, it resides out-of-the-way at include/nuttx/lib/math.h because it
conflicts too often with the system math.h. If ARCH_MATH_H=y is
defined, however, the top-level makefile will copy the redirecting
math.h header file from include/nuttx/lib/math.h to include/math.h. math.h
will then include the architecture-specific version of math.h that you
must provide at nuttx/arch/>architecture</include/math.h.
#ifdef CONFIG_ARCH_MATH_H
# include <arch/math.h>
#endif
So for the architectures that define ARCH_MATH_H=y, include/math.h
will be the redirecting math.h header file; for the architectures
that don't select ARCH_MATH_H, the redirecting math.h header file
will stay out-of-the-way in include/nuttx/.
config ARCH_FLOAT_H
bool "float.h"
default n
---help---
The float.h header file defines the properties of your floating
point implementation. It would always be best to use your
toolchain's float.h header file but if none is available, a default
float.h header file will provided if this option is selected. However
there is no assurance that the settings in this float.h are actually
correct for your platform!
config ARCH_STDARG_H
bool "stdarg.h"
default n
---help---
There is also a redirecting version of stdarg.h in the source tree
as well. It also resides out-of-the-way at include/nuttx/lib/stdarg.h.
This is because you should normally use your toolchain's stdarg.h
file. But sometimes, your toolchain's stdarg.h file may have other
header file dependencies and so may not be usable in the NuttX build
environment. In those cases, you may have to create a architecture-
specific stdarg.h header file at nuttx/arch/<architecture>/include/stdarg.h
If ARCH_STDARG_H=y is defined, the top-level makefile will copy the
re-directing stdarg.h header file from include/nuttx/lib/stdarg.h to
include/stdarg.h. So for the architectures that cannot use their
toolchain's stdarg.h file, they can use this alternative by defining
ARCH_STDARG_H=y and providing. If ARCH_STDARG_H, is not defined, then
the stdarg.h header file will stay out-of-the-way in include/nuttx/.
