[ECOS] Linker errors while linking ecos application with libc.a

[ECOS] Linker errors while linking ecos application with libc.a

[Balasaravanan P]

Hi,

I was linking my ecos application with libc.a. I received the
following linker errors.
I am not able to figure out a fix for this. 
Can anyone please let me know how this can be fixed?

eCos does not have a libc.a, so you should not be linking to it.

Re: [ECOS] Linker errors while linking ecos application with libc.a

[Balasaravanan P]

Basically I am using sprintf, strcmp, strcpy ...

If I am not linking libc.a I am receving lot of undefined errors for
all these functions.

Can you please tell me which library to be used to get the image built.

Regards,
Bala.

If eCos is configured to build these functions they will be in
libtarget.a.

Which template are you using. The minimal template does not have these
but the default template does.

Re: [ECOS] Linker errors while linking ecos application with libc.a

[Balasaravanan P]

Thanks Andrew,
I changed the template from kernel to default which provides most of
these functions.

But still one error persists for the call "localtime" in which it says
"localtime_r" undefined.

For this I tried enbling "Provide BSD compatiblity functions" & "Posix
time functions" & "localtime_r"  when I enable also these options
kernel is not building it says the following error

"
ecos-c/New/eCos/ecos-2.0/packages/language/c/libc/time/v2_0/src/strptime.cxx: In

"
Please let me know if I had to enable any other options. 

Thanks,
Bala.

With the current anoncvs it should just work. There is no need to
change any configuration options.

[Balasaravanan P]

I am able to build the application now.

Actually the sting.h file was not included in the strptime.cxx in my
version of the file.

After including it, this works fine.

Thank you.
Bala.
