[mythtv] Undefined reference in libmyth

[Anton Farygin]

Hi Nigel.

Thanks for reply.

This problem in circle dependency in myth libraries.


libmythupnp reverse depends to libmyth, and libmyth depends on libmythupnp:
$ ldd -r libs/libmythupnp/libmythupnp-0.20.so|grep libmyth
         libmyth-0.20.so.0 => /usr/lib/libmyth-0.20.so.0 (0xb7bda000)
         libmythui-0.20.so.0 => /usr/lib/libmythui-0.20.so.0 (0xb716b000)

This is impossible - link libmyth with libmythupnp, and libmythupnp with 
libmyth at one time without unresolved symbols. How to fix it ?
