I have such a file ( ~/Pobrane/multi-rtl/swig/multi_rtl_swig.i ) :
/* -*- c++ -*- */
#define MULTI_RTL_API
%include "gnuradio.i" // the common stuff
%include "feval.i"
//load generated python docstrings
%include "multi_rtl_swig_doc.i"
%{
#include "multi_rtl/vector_sink_cn.h"
%}
%include "multi_rtl/vector_sink_cn.h"
GR_SWIG_BLOCK_MAGIC2(multi_rtl, vector_sink_cn);
and I get following error during make process:
[ 26%] Swig source multi_rtl_swig.i
Deprecated command line option: -modern. This option is now always on.

Of course I have these files in such directories:
gnuradio.i - /usr/include/gnuradio/swig/gnuradio.i
feval.i - /usr/include/gnuradio/swig/feval.i
This error occurred during following command ( I know from make VERBOSE=1 command ):

I wonder where this error comes from, what it is caused and how can I fix it.
EDIT
I know what's causing the problem. I use deprecated ${GNURADIO_RUNTIME_INCLUDE_DIRS} macro. After replacing
foreach(incdir ${GNURADIO_RUNTIME_INCLUDE_DIRS})
list(APPEND GR_SWIG_INCLUDE_DIRS ${incdir}/gnuradio/swig)
endforeach(incdir)
with
list(APPEND GR_SWIG_INCLUDE_DIRS "/usr/local/include/gnuradio/swig")
list(APPEND GR_SWIG_INCLUDE_DIRS "/usr/include/gnuradio/swig")
everything works. However, this is a temporary solution. How can I implement similar functionality in gnuradio 3.8?
