Thank you Philipp, I will turn to Imperas with my question. Greetings from Bochum, Mehmet

Hi, I work on a simple System on Chip. I have a cpu, a bus and a ram. When I compile the following code I got a error message. The code is: #include <stdlib.h> #include <stdio.h> #include <string.h> #include "systemc.h" //Use an OVP Microblaze 8.2 processor model #include "xilinx.ovpworld.org/processor/microblaze/1.0/tlm2.0/microblaze_V8_20.igen.hpp" #include "ovpworld.org/modelSupport/tlmPlatform/1.0/tlm2.0/tlmPlatform.hpp" //Use Memory #include "ovpworld.org/memory/ram/1.0/tlm2.0/tlmMemory.hpp" //Use Bus #include "ovpworld.org/modelSupport/tlmDecoder/1.0/tlm2.0/tlmDecoder.hpp" icmAttrListObject *attrsForcpu1() { icmAttrListObject *userAttrs = new icmAttrListObject; return userAttrs; } int sc_main(int argc, char *argv[0]) { //Instantiate OVP platform icmTLMPlatform *platform = new icmTLMPlatform("icm", ICM_VERBOSE | ICM_STOP_ON_CTRLC| ICM_ENABLE_IMPERAS_INTERCEPTS); //Instantiate RAM ram *speicher = new ram("speicher","sp1", 0x100000); //Instantiate Bus decoder<NR_OF_INITIATORS,NR_OF_TARGETS> decoder<1,1> *bus = new decoder<1,1>("bus"); //Instantiate the processor microblaze_V8_20 *core = new microblaze_V8_20("core", 0, ICM_ATTR_DEFAULT, attrsForcpu1()); //Bind CPU with Bus core->INSTRUCTION.socket(bus->target_socket[0]); core->DATA.socket(bus->target_socket[1]); //Bind Bus with RAM bus->initiator_socket[1](speicher->sp1); bus->setDecode(1, 0x00200000, 0x002fffff); // Load application core->loadLocalMemory("application.MICROBLAZE.elf", 1, 1, 1); //Start and stop the simulation sc_core::sc_start(); sc_core::sc_stop(); //Deallocate objects delete core; delete platform; return 0; } The error message on the console is: make -f $IMPERAS_HOME/ImperasLib/so/buildutils/Makefile.TLM.platform PLATFORM=mb_tlm # Compiling Build/Linux32/usr/mb_tlm.o # Linking mb_tlm.Linux32.exe Build/Linux32/tlm/tlmSupport.a(tlmPlatform.o): In function `~sc_trace_file': /usr/local/systemc-2.3.0//include/sysc/tracing/sc_trace.h:168: undefined reference to `vtable for sc_core::sc_trace_file' Build/Linux32/tlm/tlmSupport.a(tlmPlatform.o): In function `time_advance': /Imperas.20130315//ImperasLib/source/ovpworld.org/modelSupport/tlmPlatform/1.0/tlm2.0/tlmPlatform.hpp:93: undefined reference to `sc_core::sc_trace_file::sc_trace_file()' Build/Linux32/tlm/tlmSupport.a(tlmPlatform.o).rodata._ZTV12time_advance[vtable for time_advance]+0x74): undefined reference to `sc_core::sc_trace_file::space(int)' Build/Linux32/tlm/tlmSupport.a(tlmPlatform.o).rodata._ZTI12time_advance[typeinfo for time_advance]+0x8): undefined reference to `typeinfo for sc_core::sc_trace_file' collect2: ld returned 1 exit status make: *** [mb_tlm.Linux32.exe] error 1 I don't know what is wrong with TLM.

Hi Philipp, I thank you a lot for your quickly answer. I configured my SystemC configure options by invoking ../configure --disable-async-updates --prefix=/usr/local/systemc-2.3.0. Now I don't have linking problems anymore. Actually I don't need the pthread functionality. But for the case I need it: Do I only have to write SYSTEMC_CXX_FLAGS=-pthread in my Makefile? Here are the error message I got before I disabled the "async_request_update" feature: make -f $IMPERAS_HOME/ImperasLib/source/buildutils/Makefile.TLM.platform Platform= PLATFORM=OVPsim_microblaze_tlm2.0 g++ -o platform.Linux32.exe Build/Linux32/usr/local/platform.o -L/Imperas.20130315/bin/Linux32 -lRuntimeLoader /usr/local/systemc-2.3.0/lib-linux/libsystemc.a -m32 Build/Linux32/tlm/tlmSupport.a /usr/local/systemc-2.3.0/lib-linux/libsystemc.a(sc_prim_channel.o): In function `sc_core::sc_host_mutex::trylock()': sc_prim_channel.cpp:(.text._ZN7sc_core13sc_host_mutex7trylockEv[sc_core::sc_host_mutex::trylock()]+0x1c): undefined reference to `pthread_mutex_trylock' collect2: ld return 1 make: *** [platform.Linux32.exe] Error 1 Thank you once again. Greetings from Bochum Mehmet

Hi, I have same problem. I set SYSTEMC_CXX_FLAGS with export SYSTEMC_CXX_FLAGS=-pthread. After that I tried to compile it again and I got the same error. I don't know what I should do. Can you help me, please? By the way how can I add "--disable-async-updates" to my SystemC configure options. Thank you in advance.

Hi, now it works. Thank you very much.

Hello everyone, I’m new in systemc and in this forum. I successfully downloaded and installed systemc-2.3.0 on MSVC-2010 (Windows 7) I can compile and run the examples. BUT when I write an own program it doesn’t work. For example I wrote this simple program. #include "systemc.h"#define WIDTH 4 SC_MODULE(adder) { sc_in<sc_uint<WIDTH> > a, b; sc_out<sc_uint<WIDTH> > sum; void do_add() { sum.write(a.read() + b.read()) } SC_CTOR(adder) { SC_METHOD(do_add); sensitive << a << b; } }; systemc.lib(sc_main_main.obj) : error LNK2019: unresolved external symbol > _sc_main referenced in function _sc_elab_and_sim > Debug/addieren.exe : fatal error LNK1120: 1 unresolved externals It seems that the compiler can’t find systemc.lib, but I have add additional libraries in the properties and set the environment variable. I checked it many times but I always got the above-mentioned messages. Can you help me? Thanks in advance. Regards, Aydin Uni Bochum
