adding -lm to LDFLAGS should solve the "undefined reference to `sin'".

missing dn_skipname can be solved in 2 different ways, disabling the enumroute module or implement a dn_skipname in enumerate.cpp.

Skipping enumroute should be done int eh configure.in test:

keeping enumroute is easy too, just add a dn_skipname in modules/enumroute.cpp:

#ifdef __UCLIBC__
static int dn_skipname(...)
...
#endif

I dunno what you prefer.

yate-1.2.0-dn_skipname.patch

adds dn_skipname so we dont need to diable the enumroute module on uclibc.

Almost fixed, thanks

Can you check if this is working with yate-2.0.0 and provide a patch if needed ?

Thanks.
