Problem with building E2 with libsigc++ 2.X

[ngc1927]

...
In the last week I have been busy adding the player in the form of the ServiceMP3-plugin and it now compiles wiithout errors.
..

Hi Audionek, I search to build 'enigma2_servicemp3' ..not compile, return this error:

In file included from pythonmodule.cpp:1:0:
servicemp3.h20: fatal error: common.h: No such file or directory
#include <common.h>
^
compilation terminated.
Makefile:502: recipe for target 'pythonmodule.lo' failed

..any suggestion?. ..thx.
