No Worries - thanks for your help already :) Hmmm looks like this is the relevant source in libc/misc/internals/__uClibc_main.c #if defined (__UCLIBC_CTOR_DTOR__) && !defined (__UCLIBC_FORMAT_SHARED_FLAT__) extern void _dl_app_init_array(void); extern void _dl_app_fini_array(void); # ifndef SHARED /* These magic symbols are provided by the linker. */ extern void (*__preinit_array_start []) (void) attribute_hidden; ... I think my correct action is to look at getting the crt[ni].o to build without (__UCLIBC_CTOR_DTOR__) defined. I got stuck at the weekend on this, but I'll have another go at following the make rules tonight after work. Cheers, > Carmelo Thanks Again -- Kieran
