[ECOS] Adding string library, with SERIAL and DEBUG excluded.

[ECOS] Adding string library, with SERIAL and DEBUG excluded.

[Erik Christiansen]

It looks like CYGBLD_ISO_STRING_BSD_FUNCS_HEADER should enable the
string library (BSD string functions), but if I uncomment:

    # user_value 0 0

is there some magic in the presence of two values, that must be dealt
with? Since the two bit "booldata" can only have 3 other values, I can
muck about with them. Maybe I can work it out from the code, but if
anyone knows already, it'd be great.

eCos is chugging nicely on our card, with no knowledge of serial I/O.
Now string functions are needed, and it seems a waste to link in newlib
when it looks possible to get these functions to pop up in libtarget.a
with a little judicious configuring.

What template are you using? Most templates have string functions
already so you should not have to do anything. 

If you are using the minimal template then all you should need to do
is:

ecosconfig add libc_string

and all these configuration options will be set automagically.

BTW, booldata means that the first value is bool and the second is
data. Data can be anything, so its not four combination its an
infinate number. You should find that it ends up with 

1 <cyg/libc/string/bsdstring.h>

[ECOS] error on i386

[Gonçalo Antunes]

Hi

I updated my eCos Repository last week (I haven't done it for a long 
while...) and now I have an error wich I cannot overtake...

I started my config.ecc with the i386realtek template.
added the HTTP, CPuload, FreeBSD, networking, and common ethernet packages..
and now I get an error on the 'make tests'.
I'm using the startup method 'FLOPPY' an ld returns an error on 
vectors.o:...    undefined reference... 'hal_interrupt_saved_state' .

if  I  change the startup method to RAM, the error does not appear...
I really need to have it running from the FLOPPY...

I'm using the config tool 2.0... I tried to install the 2.11, followed the 
instructions but I get an error of missing libraries....

Can you help?

Thank you very much.

Gonçalo Antunes.
