Linking problem when removing ISO C standard input/output functions

["Alois Z." <alois.zoitl@xxxxxx>]

Hi,

I have a very strange problem. I'm currently removing not needed features from my eCos configuration in order to save some space for a rather small system. For this I don't need the standard input/output functions.
However every time I try to unload the ISO C library standard input/output functions package I get the following linker error when linking the application:

/ecos-c/cygwin/opt/ecos/ecos-3.0/packages/hal/common/v3_0/src/hal_if.c:1065: undefined reference to
`cyg_hal_plf_comms_init'

I'm working an an AT91SAM7S256. I already compared the ecc files of working versions and not working versions but IMHO I see only changes that reflect the removing of standard i/o functions.

Thanks in advance for any hint.

Alois
