The pdf was moved from there quite a while ago:

lunn@londo:~/eCos/htdocs/docs-latest/pdf$ cvs log redboot.pdf

Move to beside rest of redboot docs

I don't know where exactly it was moved to. Jifl?

Anyway, you can build it yourself with:

make pdfa4
or
make pdfletter

in the packages/redboot/current/doc directory.

[ECOS] Possible omission in Lwip?

[Birahim Larou Fall]

In file  eCos\packages\net\lwip_tcpip\current\include\lwip,  struct 
timeval is defined if LWIP_TIMEVAL_PRIVATE is defined, but function 
lwip_select() use struct timeval as an argument and it's declared in 
sockets.h with or without LWIP_TIMEVAL_PRIVATE defined. Of course LWIP 
compile witout any error because each time that sockets is included, 
LWIP_TIMEVAL_PRIVATE is first defined.
/* 
 * only define this in api_sockets_wrapper.c so it does not interfere
 * with other projects namespaces where timeval is present
 */ 
#ifdef LWIP_TIMEVAL_PRIVATE
  struct timeval {
    long    tv_sec;         /* seconds */
    long    tv_usec;        /* and microseconds */
  };
#endif

int lwip_select(int maxfdp1, fd_set *readset, fd_set *writeset, fd_set 
*exceptset,
                struct timeval *timeout);

So what is the problem?

The problem, Mr Andrew, is that I include 
eCos\packages\net\lwip_tcpip\current\include\lwip in my source file and I 
don't want to define LWIP_TIMEVAL_PRIVATE (because I don't use TIMEVAL) so 
IT generates an error.

So what is the problem?

That is a directory, not a file, so you cannot #include it.

It looks like you should be including 

<lwip/network.h>

This also does not look right either

lunn@londo:~/eCos/anoncvs-clean/packages/net/lwip_tcpip/current/include$ grep -n -r LWIP_TIMEVAL_PRI *
lwip/sockets.h:212:#ifndef LWIP_TIMEVAL_PRIVATE
lwip/sockets.h:213:#define LWIP_TIMEVAL_PRIVATE 1
lwip/sockets.h:216:#if LWIP_TIMEVAL_PRIVATE

212:#ifndef LWIP_TIMEVAL_PRIVATE
213:#define LWIP_TIMEVAL_PRIVATE 1
214:#endif
215:
216:#if LWIP_TIMEVAL_PRIVATE
  struct timeval {
    long    tv_sec;         /* seconds */
    long    tv_usec;        /* and microseconds */
  };
#endif

So unless you have defined LWIP_TIMEVAL_PRIVATE timeval will be
declared. However all this is inside #ifndef FD_SET so that could be
the cause of the problem.

Please provide a test case that i can compile and see the error.
