Looking for implementation of IPv6 option management (RFC3542) on embedded

[Lev Olshvang]

Hi list ,


I am working on embedded 2.6.39 platform with a  uclibc 0.9.32.

It turns out that neither uclibc, nor newlib implements   IPv6 option 
management (RFC3542) , such as
inet6_opt_init(),
inet6_opt_append() functions.

The newlib for example just provide include reference

newlib-1.20.0/newlib/libc/sys/linux/include/netinet6/in6.h:extern int 
inet6_opt_append __P((void *, size_t, int, uint8_t ,)

  but how it is
supposed to resolve external symbol ?

ThanX,
Lev
