[ECOS] ecos for i386 target

[ECOS] ecos for i386 target

[Santanu Chatterjee]

Hello everybody,

I was trying to compile ecos-2.0 for the i386 pc target. The building of the 
libraries went smoothly. No errors.
However, when I tried to run make on the example programs, I got the 
following errors :

collect2: ld returned 1 exit status
make: *** [hello] Error 1
----------------------------------------------------

It seems like somekind of error related to the linker, but I can't figure out
what it is or how to fix it (I'm still very much a newbie to ecos). 

I downloaded the latest ecos sources from anoncvs and tried the same, 
but I get the same errors. I'm using gcc-3.3 (I'm using the same, without
any prefix to gcc for the i386 target as well) on Ubuntu Warty.

Also, the above procedure worked well for the linux synthetic target, but
it is not working for i386 target.

Can anyone from this list please provide some guidelines as to how to
fix this error. My present intention is to boot ecos from a floppy using redboot
and then run a sample program with no other OS running, so that I can 
see the thread switching timings using an oscillator.

Thank you in advance.

Regards,
Santanu

Use the i386 toolchain available from
http://ecos.sourceware.org/getstart.html.

The toolchain you are using generates calls to libc which eCos does
not use. The older toolchain does not have this problem.

Thanks.
I will do as you suggested. Will post back if I face any problems.
