使用CMake设置SystemC项目:未定义引用`sc_core

Question

我正在尝试使用CMake在SystemC中构建一个简单的hello世界.

这是SystemC文件main.cpp:

#include <systemc.h>

using namespace std;

SC_MODULE (hello_world) {
  SC_CTOR (hello_world) {
  }

  void say_hello() {
    cout << "Hello World SystemC" << endl;
  }
};

int sc_main(int argc, char* argv[]) {
  hello_world hello("HELLO");
  hello.say_hello();
  return(0);
}

这是CMakeLists.txt:

cmake_minimum_required(VERSION 3.1)
project(SystemCExample)

set (CMAKE_PREFIX_PATH /usr/local/systemc-2.3.2)

include_directories(${CMAKE_PREFIX_PATH}/include)

find_library(systemc systemc ${CMAKE_PREFIX_PATH}/lib-linux64)
link_directories(${CMAKE_PREFIX_PATH}/lib-linux64)

set(CMAKE_CXX_STANDARD 11) # C++11...

set(CMAKE_CXX_STANDARD_REQUIRED ON) #...is required...

set(CMAKE_CXX_EXTENSIONS OFF) #...without compiler extensions like gnu++11

aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})

target_link_libraries(SystemCExample systemc)

我一直收到错误:

/usr/local/systemc-2.3.2/include/sysc/kernel/sc_ver.h:179:错误:未定义引用`sc_core :: sc_api_version_2_3_2_cxx201103L <&sc_core :: SC_DISABLE_VIRTUAL_BIND_UNDEFINED _> :: sc_api_version_2_3_2_cxx201103L(sc_core :: sc_writer_policy)'

它指向sc_ver.h到该行:

api_version_check
(
  SC_DEFAULT_WRITER_POLICY
);

当我用另一个简单的例子替换main.cpp时,也会出现错误消息.我该如何解决？

很可能你用C++ 98构建了SystemC.这是默认的.目前,它要求您在库构建期间和应用程序中使用相同的C++标准.

以下是使用CMake构建SystemC 2.3.2的步骤

1. 下载SystemC 2.3.2,解压缩,将目录更改为systemc-2.3.2

   cd /path/to/systemc-2.3.2

2. 创建构建目录:

   mkdir build

3. 配置具有C++ 11支持的SystemC构建.我还建议在Debug模式下构建它,这有助于学习.稍后您可以切换到发布版本以加速模拟

   cmake ../-DCMAKE_CXX_STANDARD = 11 -DCMAKE_BUILD_TYPE = Debug

4. 建立

   cmake --build.

CMake将自动将SystemC库目标导出到用户包注册表:https://cmake.org/cmake/help/v3.0/manual/cmake-packages.7.html#user-package-registry

您可以选择将其安装在某处,阅读CMake手册以了解具体方法.

现在尝试创建示例SystemC项目:

main.cpp中

#include <systemc.h>

SC_MODULE (hello_world) {
    SC_CTOR (hello_world)
    {
        SC_THREAD(say_hello);
    }

    void say_hello()
    {
        cout << "Hello World SystemC" << endl;
    }

};

int sc_main(int argc, char* argv[])
{
    hello_world hello("HELLO");
    sc_start();

    return (0);
}

的CMakeLists.txt

cmake_minimum_required(VERSION 3.0)
project(test_systemc)

find_package(SystemCLanguage CONFIG REQUIRED)
set (CMAKE_CXX_STANDARD ${SystemC_CXX_STANDARD})

add_executable(test_systemc main.cpp)
target_link_libraries(test_systemc SystemC::systemc)

构建,运行,预期输出:

./test_systemc
