Hello everyone, I have successfuly compiled SystemC-2.3.0 under VS2012. Compilation: For a system description and compilation, I had to enable static linking the following way, aside from configuring the include and library directories and the library name. Properties->configuration properties->C/C++->Code Generation Runtime Library set to Multi-threaded Debug (\MTd) After that, I was able to compile the simulation project. Execution: During execution, Windows throws an exception for the DCAST of line 359 on sc_thread_process.cpp. This is executed by the call to SC_THREAD(run) in the "CPU" constructor. The related code can be found enclosed. Console output: Error: (E549) uncaught exception: Access violation - no RTTI data! In file: c:\users\raul\documents\visual studio 2012\projects\systemc-2.3.0\src\sysc\kernel\sc_except.cpp:98 Visual Studio output: First-chance exception at 0x0135EF3F in coprocessor_func.exe: 0xC0000005: Access violation reading location 0x00000005. First-chance exception at 0x74D54B32 in coprocessor_func.exe: Microsoft C++ exception: std::__non_rtti_object at memory location 0x007EF570. First-chance exception at 0x74D54B32 in coprocessor_func.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000. First-chance exception at 0x74D54B32 in coprocessor_func.exe: Microsoft C++ exception: sc_core::sc_report at memory location 0x007EE304. The program '[4260] coprocessor_func.exe' has exited with code 1 (0x1). Could this be related to the issue that dynamic cast should not be called from within a constructor because the object is not yet fully built? References: Under item 6: http://en.cppreferen...ge/dynamic_cast This is an example that I am using without issues under Linux. Any ideas of what can be going wrong? Thanks in advance, Raul Fajardo Code: #include <systemc.h> #include <iostream> using namespace std; class CoProcessor { sc_time m_process_time; public: CoProcessor() { m_process_time = sc_time(20, SC_US); } unsigned int sum(unsigned int a, unsigned int { unsigned int tmp = a + b; wait(m_process_time); return tmp; } }; class CPU : public sc_module { CoProcessor co_cpu; public: SC_HAS_PROCESS(CPU); //enables the definition of SC_THREAD or SC_METHOD (SC_METHOD has sensitivity and never ends) CPU(sc_module_name nm) : sc_module(nm) { SC_THREAD(run); //registers the function to the simulation kernel, enables wait() } void run() { unsigned int a, b, c; b = 10; c = 5; a = co_cpu.sum(b, c); cout << "Computation result of " << b << " + " << c << ": " << a << endl; cout << "Algorithm was run in " << sc_time_stamp() << endl; } }; int sc_main(int argc, char * argv[]) { CPU processor("main_processor"); sc_start(500, SC_US); //simulate for 500 microseconds return 0; }
