=============================
|
||||
|
||||
From http://tech.groups.yahoo.com/group/nuttx/message/2900:
|
||||
|
||||
"The build was quite simple:
|
||||
|
||||
I used mingw installer and I had to install two packages that the
|
||||
automated mingw setup does not bring by default:
|
||||
|
||||
* mingw-get update
|
||||
* mingw-get install mingw32-pdcurses mingw32-libpdcurses
|
||||
* mingw-get install msys-regex msys-libregex
|
||||
|
||||
(grep the output of mingw-get list if I got the names wrong)
|
||||
|
||||
Then I had to change some things in mconf code, it was quite simple to
|
||||
understand the make errors.
|
||||
|
||||
* The first of them is to disable any use of uname() in symbol.c and
|
||||
replace the uname output by a constant string value (I used MINGW32-MSYS),
|
||||
|
||||
* The second one is related to the second parameter to mkdir() that has
|
||||
to disappear for windows (we don't care about folder rights) in confdata.c;
|
||||
|
||||
* And the last one of them involves #undef bool in dialog.h before including
|
||||
curses.h (CURSES_LOC), around line 30.
|
||||
|
||||
I wrapped all of my changes in #if(n)def __MINGW32__, but that is not
|
||||
sufficient to make that work everywhere, I think.
|
||||
|
||||
So mconf itself has some portability issues that shall be managed in a
|
||||
cleaner way, what I did was just hacks, I don't think they are
|
||||
acceptable by mconf upstream maintainers.
|
||||
|
||||
Here is the magic incantation to get the whole thing working. It seems
|
||||
that the configure script is not so good and does not bring the required
|
||||
bits to link libregex.
|
||||
|
||||
CFLAGS="-I/mingw/include -I/usr/include" LDFLAGS="-Bstatic -L/mingw/lib
|
||||
-L/usr/lib -lregex" ./configure --enable-frontends=mconf --enable-static
|
||||
--disable-shared
|
||||
|
||||
So the message I want to pass is that native "make menuconfig" in
|
||||
windows IS POSSIBLE, I have done it in a few minutes."

---help---
|

strerror() is useful because it decodes 'errno' values into a human readable
|
||||
strings. But it can also require a lot of memory. If this option is selected,
|
||||
strerror() will still exist in the build but it will not decode error values.
|
||||
This option should be used by other logic to decide if it should use strerror()
|
||||
or not. For example, the NSH application will not use strerror() if this
|
||||
option is not selected; perror() will not use strerror() is this option is not
|
||||
selected (see also NSH_STRERROR).

|
||||
If this option is selected, then strerror() will use a shortened string when
|
||||
it decodes the error. Specifically, strerror() is simply use the string that
|
||||
is the common name for the error. For example, the 'errno' value of 2 will
|
||||
produce the string "No such file or directory" is LIBC_STRERROR_SHORT

config ARCH_ROMGETC

bool "Support for ROM string access"

default n
|

---help---
|
||||
In Harvard architectures, data accesses and instruction accesses
|
||||
occur on different busses, perhaps concurrently. All data accesses
|
||||
are performed on the data bus unless special machine instructions
|
||||
are used to read data from the instruction address space. Also, in
|
||||
the typical MCU, the available SRAM data memory is much smaller that
|
||||
the non-volatile FLASH instruction memory. So if the application
|
||||
requires many constant strings, the only practical solution may be
|
||||
to store those constant strings in FLASH memory where they can only
|
||||
be accessed using architecture-specific machine instructions.
|
||||
|
||||
If ARCH_ROMGETC is defined, then the architecture logic must export
|
||||
the function up_romgetc(). up_romgetc() will simply read one byte
|
||||
of data from the instruction space.
|
||||
|
||||
If ARCH_ROMGETC, certain C stdio functions are effected: (1) All
|
||||
format strings in printf, fprintf, sprintf, etc. are assumed to lie
|
||||
in FLASH (string arguments for %s are still assumed to reside in SRAM).
|
||||
And (2), the string argument to puts and fputs is assumed to reside
|
||||
in FLASH. Clearly, these assumptions may have to modified for the
|
||||
particular needs of your environment. There is no "one-size-fits-all"
|
||||
solution for this problem.

lib
|
||||
===
|
||||
|
||||
This directory contains numerous, small functions typically associated with
|
||||
what you would expect to find in a standard C library. The sub-directories
|
||||
in this directory contain standard interface that can be executed by user-
|
||||
mode programs.
|
||||
|
||||
Normally, NuttX is built with no protection and all threads running in kerne-
|
||||
mode. In that model, there is no real architectural distinction between
|
||||
what is a kernel-mode program and what is a user-mode program; the system is
|
||||
more like on multi-threaded program that all runs in kernel-mode.
|
||||
|
||||
But if the CONFIG_NUTTX_KERNEL option is selected, NuttX will be built into
|
||||
distinct user-mode and kernel-mode sections. In that case, most of the
|
||||
code in the nuttx/ directory will run in kernel-mode with with exceptions
|
||||
of (1) the user-mode "proxies" found in syscall/proxies, and (2) the
|
||||
standard C library functions found in this directory. In this build model,
|
||||
it is critical to separate the user-mode OS interfaces in this way.
|
||||
|
||||
Sub-Directories
|
||||
===============
|
||||
|
||||
The files in the lib/ directory are organized (mostly) according which file
|
||||
in the include/ directory provides the prototype for library functions. So
|
||||
we have:
|
||||
|
||||
libgen - libgen.h
|
||||
fixedmath - fixedmath.h
|
||||
math - math.h
|
||||
mqueue - pthread.h
|
||||
net - Various network-related header files: netinet/ether.h, arpa/inet.h
|
||||
pthread - pthread.h
|
||||
queue - queue.h
|
||||
sched - sched.h
|
||||
semaphore - semaphore.h
|
||||
stdio - stdio.h
|
||||
stdlib - stdlib.h
|
||||
string - string.h
|
||||
time - time.h
|
||||
unistd - unistd.h
|
||||
|
||||
There is also a misc/ subdirectory that contains various internal functions
|
||||
and interfaces from header files that are too few to warrant their own sub-
|
||||
directory:
|
||||
|
||||
misc - Nonstandard "glue" logic, debug.h, crc32.h, dirent.h
|
||||
|
||||
Library Database
|
||||
================
|
||||
|
||||
Information about functions available in the NuttX C library information is
|
||||
maintained in a database. That "database" is implemented as a simple comma-
|
||||
separated-value file, lib.csv. Most spreadsheets programs will accept this
|
||||
format and can be used to maintain the library database.
|
||||
|
||||
This library database will (eventually) be used to generate symbol library
|
||||
symbol table information that can be exported to external applications.
|
||||
|
||||
The format of the CSV file for each line is:
|
||||
|
||||
Field 1: Function name
|
||||
Field 2: The header file that contains the function prototype
|
||||
Field 3: Condition for compilation
|
||||
Field 4: The type of function return value.
|
||||
Field 5 - N+5: The type of each of the N formal parameters of the function
|
||||
|
||||
Each type field has a format as follows:
|
||||
|
||||
type name:
|
||||
For all simpler types
|
||||
formal type | actual type:
|
||||
For array types where the form of the formal (eg. int parm[2])
|
||||
differs from the type of actual passed parameter (eg. int*). This
|
||||
is necessary because you cannot do simple casts to array types.
|
||||
formal type | union member actual type | union member fieldname:
|
||||
A similar situation exists for unions. For example, the formal
|
||||
parameter type union sigval -- You cannot cast a uintptr_t to
|
||||
a union sigval, but you can cast to the type of one of the union
|
||||
member types when passing the actual paramter. Similarly, we
|
||||
cannot cast a union sigval to a uinptr_t either. Rather, we need
|
||||
to cast a specific union member fieldname to uintptr_t.
|
||||
|
||||
NOTE: The tool mksymtab can be used to generate a symbol table from this CSV
|
||||
file. See nuttx/tools/README.txt for further details about the use of mksymtab.

* Description:
|

* The readdir() function returns a pointer to a dirent

* structure representing the next directory entry in the
|

* directory stream pointed to by dir. It returns NULL on
|
||||
* reaching the end-of-file or if an error occurred.
|
||||
*
|
||||
* Inputs:
|
||||
* dirp -- An instance of type DIR created by a previous
|
||||
* call to opendir();
|
||||
* entry -- The storage pointed to by entry must be large
|
||||
* enough for a dirent with an array of char d_name
|
||||
* members containing at least {NAME_MAX}+1 elements.
|
||||
* result -- Upon successful return, the pointer returned
|
||||
* at *result shall have the same value as the
|
||||
* argument entry. Upon reaching the end of the directory
|
||||
* stream, this pointer shall have the value NULL.
|
||||
*
|
||||
* Return:
|
||||
* If successful, the readdir_r() function return s zero;
|
||||
* otherwise, an error number is returned to indicate the
|
||||
* error.

By default, no math library will be provided by NuttX. In this this case, it
|
||||
is assumed that (1) no math library is required, or (2) you will be using the
|
||||
math.h header file and the libm library provided by your toolchain.
|
||||
|
||||
This is may be a very good choice is possible because your toolchain may have
|
||||
have a highly optimized version of libm.
|
||||
|
||||
Another possibility is that you have a custom, architecture-specific math
|
||||
libary and that the corresponding math.h file resides at arch/<architecture>/include/math.h.
|
||||
The option is selected via ARCH_MATH_H. If ARCH_MATH_H is selected,then the include/nuttx/math.h
|
||||
header file will be copied to include/math.h where it can be used by your applications.
|
||||
|
||||
If ARCH_MATH_H is not defined, then this option can be selected to build a generic,
|
||||
math library built into NuttX. This math library comes from the Rhombus OS and
|
||||
was written by Nick Johnson. The Rhombus OS math library port was contributed by
|
||||
Darcy Gong.
