Hi

I am able to run Hello.cpp and other simple programs - but when try for the code below

I added

        sc_signal< sc_int<4> > a,b,sum;

to my .cpp , i am getting the following issue during linking time

`sc_dt::sc_int_base::print(std::ostream&) const':
/usr/local/systemc-2.3/include/sysc/datatypes/int/sc_int_base.h:865: undefined reference to `sc_dt::sc_int_base::to_string[abi:cxx11](sc_dt::sc_numrep, bool) const'
collect2: error: ld returned 1 exit status
Makefile.rules:150: recipe for target 'a.x' failed

 

My code is pasted below

#include "systemc.h"
SC_MODULE(tff_async_reset){
    sc_in <bool> data,clk,reset;
    sc_out <bool> q;
    bool q_l;
    void atff(){
        if(~reset.read()){
            q_l = 0;
        } else if(data.read()) {
            q_l = !q_l;
        }
        q.write(q_l);
}
    SC_CTOR(tff_async_reset) {
        SC_METHOD (atff);
        sensitive << reset;
        sensitive << clk.pos();
}
};

    int sc_main(int argc , char* argv[]) {
        sc_signal< sc_int<4> > a,b,sum;
        sc_signal<bool> clk;
        return(0);
    }

 

I use the below command for compiling/linking

g++  -g -Wall -pedantic -Wno-long-long -Werror -L. -L.. -L /usr/local/systemc-2.3/lib-linux64/ -Wl,-rpath=/usr/local/systemc-2.3/lib-linux64 -o a.x tff_async_reset.o -lsystemc -lm

 

If I remove the line sc_signal< sc_int<4> > a,b,sum; 

the above command passes

Any help ?

Can you please share some details about your build environment such as compiler version you are using, etc.?

Also kindly share the compilation option used the command that you have shared is showing only the use of object files for input and final executable "a.x" to be compiled and linked.

 

Currently I am able to build the using this command on my system:

g++ -g -Wall -std=c++11 -I $SYSTEMC_HOME/include -L $SYSTEMC_HOME/lib-linux64 -o test.run test.cpp -lsystemc

where g++ -v: g++ 5.4.0

On modern GCC versions (starting with 5.x), you the binary interface changed between C++03 and C++11 mode.  You need to build your SystemC library with the same compiler (settings) to get the C++11 version of the functions.

Hope that helps,
