如何使用cmake将第三方库添加到gnuradio块?

标签: c++ cmake gnuradio

最近两天我试图在gnuradio中创建新块,但是当我尝试执行流程图时,我经常遇到错误:

GET /images
GET /image/<image_id>
POST /createImage

我认为我试图在我的项目中使用第三方库(opennn)存在一些问题。在主源文件(test_impl.cc)中我导入了opennn头文件。在功能 general_work 我调用函数:

AttributeError: 'module' object has no attribute 'test'

我的lib / CMakeLists.txt(在lib文件夹中,我有自动生成的gnuradio块源文件和带有opennn库的dirs):

   int
    test_impl::general_work (int noutput_items,
                       gr_vector_int &ninput_items,
                       gr_vector_const_void_star &input_items,
                       gr_vector_void_star &output_items)
    {
      const float *in = (const float *) input_items[0];
      float *out = (float *) output_items[0];
       OpenNN::NeuralNetwork nn(8, 1, 1);

      // Do <+signal processing+>
      // Tell runtime system how many input items we consumed on
      // each input stream.
      consume_each (noutput_items);

      // Tell runtime system how many output items we produced.
      return noutput_items;
    }

我尝试添加以下代码:

########################################################################
# Setup library
########################################################################
include(GrPlatform) #define LIB_SUFFIX

include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIRS})

list(APPEND tutorial3_sources
    test_impl.cc
)

set(tutorial3_sources "${tutorial3_sources}" PARENT_SCOPE)
if(NOT tutorial3_sources)
    MESSAGE(STATUS "No C++ sources... skipping lib/")
    return()
endif(NOT tutorial3_sources)

add_library(gnuradio-tutorial3 SHARED ${tutorial3_sources})
target_link_libraries(gnuradio-tutorial3 ${Boost_LIBRARIES} ${GNURADIO_ALL_LIBRARIES})
set_target_properties(gnuradio-tutorial3 PROPERTIES DEFINE_SYMBOL "gnuradio_tutorial3_EXPORTS")

if(APPLE)
    set_target_properties(gnuradio-tutorial3 PROPERTIES
        INSTALL_NAME_DIR "${CMAKE_INSTALL_PREFIX}/lib"
    )
endif(APPLE)
########################################################################

########################################################################
include(GrMiscUtils)
GR_LIBRARY_FOO(gnuradio-tutorial3 RUNTIME_COMPONENT "tutorial3_runtime" DEVEL_COMPONENT "tutorial3_devel")

########################################################################
# Build and register unit test
########################################################################
include(GrTest)

include_directories(${CPPUNIT_INCLUDE_DIRS})

list(APPEND test_tutorial3_sources
    ${CMAKE_CURRENT_SOURCE_DIR}/test_tutorial3.cc
    ${CMAKE_CURRENT_SOURCE_DIR}/qa_tutorial3.cc
)

add_executable(test-tutorial3 ${test_tutorial3_sources})

target_link_libraries(
  test-tutorial3
  ${GNURADIO_RUNTIME_LIBRARIES}
  ${Boost_LIBRARIES}
  ${CPPUNIT_LIBRARIES}
  gnuradio-tutorial3
)

GR_ADD_TEST(test_tutorial3 test-tutorial3)

########################################################################
# Print summary
########################################################################
message(STATUS "Using install prefix: ${CMAKE_INSTALL_PREFIX}")
message(STATUS "Building for version: ${VERSION} / ${LIBVER}")

说实话,我已尝试在很多方面修改此CMake文件,但我总是收到此错误。

答案 0 :(得分:0)

您的问题为我提供了解决问题的线索,我认为这与此处描述的相同,但我不确定。我的解决方案是将缺少的外部库 yaml-cpp 添加到文件 target_link_libraries 中的 lib/CMakeLists.txt 指令,用于我的 GnuRadio 模块。

target_link_libraries(gnuradio-AUK gnuradio::gnuradio-runtime yaml-cpp)

我添加了一些 C++ YAML 代码来解析配置文件。它编译得很好,但给出了难以理解的消息:

AttributeError: module ... has no attribute ...

现在都修复了。非常感谢提供线索。
