How to compile SCV

[ollie_lin]

Hi everyone.

I'm newbie. I have some problem about build scv library. please help me to fix issue. thanks a lot.

systemC Version: systemc-2.3.3

scv Version: scv-2.0.1

ubuntu Version : Ubuntu 20.04.3 LTS

 

main.cpp:

#include <scv.h>

using namespace std;

int sc_main(int argc, char* argv[])
{
    scv_startup();
    cout << "Hello world, SCV library." << endl;

    return 0;
}

 

Makefile:

TARGET = out

IDIR = .
SDIR = .
ODIR = .

SRC = $(wildcard $(SDIR)/*.cpp)
OBJ = $(SRC:$(SDIR)/%.c=$(ODIR)/%.o)

CXX = g++
CXXFLAGS = -I$(IDIR)
CXXFLAGS += -g -O0
CXXFLAGS += -Iinclude
CFLAGS += -Wall
SCPATH = /usr/local/systemc
LIBS = -lm

$(TARGET): $(OBJ)
    $(CXX) $(CXXFLAGS) $(LDFLAGS) -I$(SCPATH)/include -L. -L$(SCPATH)/lib-linux64 -Wl,-rpath $(SCPATH)/lib-linux64 $^ $(LIBS) -o $@ -lsystemc

$(ODIR)/%.o: $(SDIR)/%.c
    $(CXX) $(CXXFLAGS) $(CFLAGS) -c $< -o $@

clean:
    $(RM) $(TARGET)

 

Error log:

g++ -I. -g -O0 -Iinclude  -I/usr/local/systemc/include -L. -L/usr/local/systemc/lib-linux64 -Wl,-rpath /usr/local/systemc/lib-linux64 main.cpp -lm -o out -lsystemc
/usr/bin/ld: /tmp/ccjI5lPb.o: in function `sc_main':

As for SystemC, you have to pass for SCV the right include path, library path and link flags. The error message indicates that the linker is not finding the implementation of `scv_startup()`, so you have to find the location of libscv.a or libscv.so on your system, add the the appropriate `-L` and `-rpath` flags and then tell the linker to also link against it. Note, the order is important: first `-lscv` and then `-lsystemc`.

Hi maehne,

add the `-lscv` flag in Makefile that compile is pass after see your comment.

thanks you for your reply.
