|
|
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 direcory. 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 CONFIG_APPS_DIR=../application.
|
|
|
|
The application direction must contain Makefile and this make
|
|
file must support the following targets:
|
|
|
|
libapps$(LIBEXT) (usually libapps.a). libapps.a is a static
|
|
library ( an archive) that contains all of application object
|
|
files.
|
|
|
|
clean. Do whatever is appropriate to clean the application
|
|
directories for a fresh build.
|
|
|
|
distclean. Clean everthing -- 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.
|
|
|
|
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.

|
|
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
|
|
CONFIG_PASS1_TARGET generates an archive). Pass 1 1ncremental (relative) link
|
|
objects should be put into the processor-specific source directory (where other

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/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/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 avaiable, 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/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/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/.
