[ECOS] Build error under current x86 - have you seen this?

[ECOS] Build error under current x86 - have you seen this?

[Ron Kundla]

Hello!

I have had a nagging problem for some time and haven't quite identified
where the root of this problem is located.

I am building from the current eCos build (taken from CVS) and when I select
the template for networking on the x86 platform, I am able to build the
library with no problems but get an error during building the tests

make: *** [tests] Error 2

The part I am concerned about is the undefined reference to '__builtin_new'
from the stream.inl file. I have looked at fdopen and there is a call to a
C++ function that does a 'set_position', which coincides with the above
error.

I have checked the eCos configuration and I do have FILEIO enabled and the
macro is defined.

Any ideas?

Are you using gcc 3 by any chance? If so, don't (yet).

If you are using something earlier, it should have been resolved by a
__builtin_new symbol in libgcc in your i386-elf-gcc.
