我有这样一个文件(~/Pobrane/multi/swig/multi_swg.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);在制作过程中，我得到了以下错误：
[ 26%] Swig source multi_rtl_swig.i
Deprecated command line option: -modern. This option is now always on.
~/Pobrane/multi-rtl/swig/multi_rtl_swig.i:5: Error: Unable to find 'gnuradio.i'

gnuradio.i - /usr/include/gnuradio/swig/gnuradio.i
feval.i - /usr/include/gnuradio/swig/feval.i此错误发生在以下命令(我从make VERBOSE=1命令中知道)：

编辑
我知道是什么引起了问题。我使用不推荐的${GNURADIO_RUNTIME_INCLUDE_DIRS}宏。更换后
foreach(incdir ${GNURADIO_RUNTIME_INCLUDE_DIRS})
list(APPEND GR_SWIG_INCLUDE_DIRS ${incdir}/gnuradio/swig)
endforeach(incdir)使用
list(APPEND GR_SWIG_INCLUDE_DIRS "/usr/local/include/gnuradio/swig")
list(APPEND GR_SWIG_INCLUDE_DIRS "/usr/include/gnuradio/swig")一切都正常。然而，这是一个暂时的解决办法。如何在gnuradio3.8中实现类似的功能？

正如您已经发现的，您需要编辑swig/CMakeLists.txt并将路径添加到GR_SWIG_INCLUDE_DIRS变量的foreach循环替换为
set(GR_SWIG_INCLUDE_DIRS $<TARGET_PROPERTY:gnuradio::runtime_swig,INTERFACE_INCLUDE_DIRECTORIES>)
set(GR_SWIG_TARGET_DEPS gnuradio::runtime_swig)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
