$(TOPDIR) to $(APPDIR)ARCHINCLUDES and ARCHXXINCLUDES DefinitionsHOSTCC and HOSTCFLAGS DefinitionsARCHCCVERSION and ARCHCCMAJOREXTRA_LIBS and EXTRA_LIBPATHS DefinitionsThe wdog timer call backs used to support a variable number of arguments.
Now they support only a single argument (PR
#1565). This eliminates
(1) the configuration option CONFIG_MAX_WDOGPARMS and the OS interfaces
wd_create() and wd_delete() * wdog timer data structures are no longer
pre-allocated. Now they are allocated by the caller of wd_start(). This (1)
eliminates the configuration options CONFIG_PREALLOC_WDOGS and
CONFIG_WDOG_INTRESERVE, (2) eliminates the type WDOG_ID which was a pointer
type to struct wdog_s, and (3) change the type of the first argument of all
remaining wdog interfaces functions from WDOG_ID to FAR struct wdog_s *.
Because of these changes, all proprietary drivers maintained by all NuttX users will require modification. The following summaries the required modifications:
Most drivers have a field in structure like WDOG_ID wdog; That must be
changed to struct wdog_s wdog; That changes the field from a pointer to a
struct wdog_s to the struct wdog_s storage itself. * Eliminate all calls
to wd_create(). The WDOG_ID is not longer managed by the timing subsystem
and the wd_create() interface has been removed. * The wd_delete()
interface has also been removed, but more care will need to be exercised:
wd_delete() also cancels any running timer so, in many case, calls to
wd_delete() should be replaced with calls to wd_cancel(). If you are certain
that the timer has never been started, then you must remove the call to
wd_delete() altogether. Calling wd_cancel() with an un-initialized struct
wdog_s instance may well cause a fatal crash. * Replace the first parameter
of all remaining wdog function calls from. For example, replace a call like ret
= wd_cancel(priv->wdog) where priv->wdog was type WDOG_ID with the call
ret = wd_cancel(&priv->wdog)where priv->wdog is now type struct wdog_s.

$(TOPDIR) to $(APPDIR)In the ‘apps’ repo, Makefiles are now using $(APPDIR) instead of $(TOPDIR).
In your custom app’s Makefile, it is recommended to change $(TOPDIR) to

With this:

[deaa6c5b7bf8445b4a300691525f60aa506be0d7](http://github.com/apache/nuttx-apps/commit/deaa6c5b7bf8445b4a300691525f60aa506be0d7)
in the NuttX ‘apps’ repository.
ARCHINCLUDES and ARCHXXINCLUDES DefinitionsAs part of an effort to unify support for uClibc++ and libc++, the C/C++ include
search path definitions ARCHINCLUDES and ARCHXXINCLUDES are now defined in
one central place in tools/Config.mk. It is no longer necessary to define
these in every board’s scripts/Make.defs. Boards included in the NuttX
repository have been updated, but if you are building NuttX for a custom board
and are using C++, you may want to make the following changes:
In your board’s configuration, ensure that you have enabled either
CONFIG_UCLIBCXX or CONFIG_LIBCXX as appropriate.
In your custom board’s scripts/Make.defs file, remove lines like these:
CINCPATH := ${shell $(INCDIR) -s “$(CC)” $(TOPDIR)$(DELIM)include} CXXINCPATH := ${shell $(INCDIR) -s “$(CC)” $(TOPDIR)$(DELIM)include$(DELIM)cxx} ARCHINCLUDES += $(CINCPATH) ARCHXXINCLUDES += $(CINCPATH) $(CXXINCPATH)
In case your scripts/Make.defs uses different names, such as ARCHINCLUDESXX
instead of ARCHXXINCLUDES, you’ll need to find all uses of that variable and
update them to use ARCHXXINCLUDES.
See * PR-1396, git commit #d32e9c38dfb0659a7f3c0cf586ba1584cd7eb3d6 in the main NuttX repository.
See also * PR-1399, git commit #6abd03d53ff9164fb17ea4aca701a49fbbf751c0.
HOSTCC and HOSTCFLAGS DefinitionsThe NuttX build system uses several binary utilities that it compiles and runs
on the host computer. To build these binaries, it needs to know the host C
compiler and C flags. Previously, every board’s scripts/Make.defs file had to
provide this information via HOSTCC and HOSTCFLAGS Definitions. As part of
an effort to simplify the build system, these definitions are now automatically
provided by logic in tools/Config.mk. Boards included in the NuttX repository
have been updated, but if you are building NuttX for a custom board, you may
want to make the following changes:
In your custom board’s scripts/Make.defs file, remove lines like these:
HOSTCC = gcc HOSTCFLAGS = -Wall -Wstrict-prototypes -Wshadow -Wundef -g -pipe
Sometimes they may look like this:
ifeq ($(CONFIG_WINDOWS_NATIVE),y) HOSTCC = mingw32-gcc.exe else HOSTCC = gcc endif
Note: These changes are OPTIONAL.
You may still set these definitions in your board’s scripts/Make.defs, and your definitions will override the ones in tools/Config.mk.
Also, you may override these definitions for a single run by providing them on the make command line. This is useful if, for example, you wish to build debug versions of these host binaries: define HOSTCFLAGS with -g on the command line.
See * PR-1398, git commit #ee875b2a260cb4cc532b8ca303c2515e24c39b4e in the main NuttX repository.
ARCHCCVERSION and ARCHCCMAJORThe ARCHCCVERSION and ARCHCCMAJOR variables are unused. Historically they were defined in many boards’ scripts/Make.defs. These were removed from all boards in the NuttX repository, but if you are building NuttX for a custom board, you may want to remove this unnecessary boilerplate.
In your custom board’s scripts/Make.defs file, remove lines like these:
ARCHCCVERSION = ${shell $(CC) -v 2>&1 | sed -n ‘/^gcc version/p’ | sed -e ‘s/^gcc version \([0-9\.]\)/\1/g’ -e ‘s/[-\ ].*//g’ -e ‘1q’} ARCHCCMAJOR = ${shell echo $(ARCHCCVERSION) | cut -d’.’ -f1}
See * PR-1344, git commit #f5311de6b42466ab5c6ef299dab0ecc417131bbe in the main NuttX repository.
EXTRA_LIBS and EXTRA_LIBPATHS DefinitionsThe EXTRA_LIBS and EXTRA_LIBPATHS make variables were previously defined in
many boards’ scripts/Make.defs files. These are now defined in a more central
location: arch/*/src/*/Toolchain.defs. Your board’s scripts/Make.defs
usually includes this file. Boards included in NuttX have been updated, but if
you are building NuttX for a custom board, you may need to update your board’s
scripts/Make.defs file to ensure you build with the correct definitions.
If you have lines like these:
EXTRA_LIBPATHS = -L “${shell dirname “$(LIBSUPXX)”}” EXTRA_LIBS = -lsupc++
You may want to do one of the following:
arch/*/src/*/Toolchain.defs, remove these lines, or * If they contain
additional needed libraries and paths not present in
arch/*/src/*/Toolchain.defs, remove any redundant definitions and change the
assignment ‘=’ to ‘+=’.See * PR-1404, git commit #4910d43ab0fc360dbddb1f8a31db2a3ee383b46d in the main NuttX repository.
OBJDUMP Definitions
These make variables were previously defined in many boards’ scripts/Make.defs
files with copy-paste duplication spanning many hundreds of files. These are now
defined in a more central location: arch/*/src/*/Toolchain.defs. Your board’s
scripts/Make.defs usually includes this file. Boards included in NuttX have
been updated, but if you are building NuttX for a custom board, you may need to
update your board’s scripts/Make.defs file to ensure you build with the
correct definitions.
If you have lines that define CC, CXX, CPP, LD, STRIP, AR, NM,
OBJCOPY, and OBJDUMP, such as these:
CC = $(CROSSDEV)gcc CXX = $(CROSSDEV)g++ CPP = $(CROSSDEV)gcc -E -P -x c LD = $(CROSSDEV)ld STRIP = $(CROSSDEV)strip –strip-unneeded AR = $(ARCROSSDEV)ar rcs NM = $(ARCROSSDEV)nm OBJCOPY = $(CROSSDEV)objcopy OBJDUMP = $(CROSSDEV)objdump
You may want to do one of the following:
arch/*/src/*/Toolchain.defs, remove these lines, or * If they are different
from the definitions in arch/*/src/*/Toolchain.defs, leave them as-is and they
will take precedence.See * PR-1426, git commit #b329e2377dd8816f37ad0408279926829efdf85d in the main NuttX repository.
The ARCROSSDEV and CROSSDEV variables always had identical values. Therefore
ARCROSSDEV has been removed and CROSSDEV is used instead. Boards included in
NuttX have been updated, but if you are building NuttX for a custom board, you
may need to update your board’s build scripts to use the CROSSDEV variable.
See * PR-1439, git commit #5efa93ec26fd8a3fd85b24a2008bb743f96027fb in the main NuttX repository.
