我正在使用 systemc 进行模拟，我收到一条错误消息，告诉我

g++ -I/opt/Xilinx-14.2/Vivado_HLS/2012.2/Linux_x86_64/tools/systemc/include/ -o testBench.exe testBench.cc -L/opt/Xilinx-14.2/Vivado_HLS/2012.2/Linux_x86_64/tools/systemc/lib -lsystemc -lm /opt/Xilinx-14.2/Vivado_HLS/2012.2/Linux_x86_64/tools/systemc/include/sysc/communication/sc_signal_ports.h：在成员函数 void sc_core::sc_in::end_of_elaboration() [with T = std: :basic_string, std::allocator >]: testBench.cc:126: 从这里实例化

/opt/Xilinx-14.2/Vivado_HLS/2012.2/Linux_x86_64/tools/systemc/include/sysc/communication/sc_signal_ports.h:285：错误：没有匹配函数调用 sc_trace(sc_core::sc_trace_file*&, const std:: basic_string, std::allocator >&, std::string&)

你们对这个错误是什么以及如何解决它有任何想法吗？

错误来自"sc_signal<std::string > inputMessage;". "T = std::string"没有为、sc_in、sc_trace、等定义一大堆模板类/函数vcd_trace。

但问题更根本：你为什么要使用std::stringa sc_signal？从代码中的注释中，您最好使用sc_uint<24>可以使用二进制字符串（如"0b1111..11".

Instead of 
   std::string input ="000111101000010010000000";
use
    sc_uint<24> input = "0b000111101000010010000000";
