我正在尝试使用 CMake 在 SystemC 中构建一个简单的 hello world。
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)
我不断收到错误:
/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_api_version_2_3_2_cxx201103L(sc_core::sc_writer _政策)'
它指向 sc_ver.h 行:
api_version_check
(
SC_DEFAULT_WRITER_POLICY
);
当我用另一个简单的示例替换 main.cpp 时,也会出现错误消息。我该如何修复它?
您很可能已经使用 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
- Download SystemC 2.3.2, unpack, change directory to systemc-2.3.2
cd /path/to/systemc-2.3.2
- Create build directory:
mkdir 构建
- Configure SystemC build with C++11 support. I also recommend to build it in Debug mode, this helps while learning. Later you can switch to Release builds to speed-up simulation
cmake ../ -DCMAKE_CXX_STANDARD=11 -DCMAKE_BUILD_TYPE=调试
- Build
cmake --build 。
CMake 会自动将 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 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个地方,阅读 CMake 手册以了解如何安装。
现在尝试创建示例 SystemC 项目:
main.cpp
#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);
}
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
SystemC 2.3.2 --- Oct 14 2017 19:38:30
