systemc: form installation to run

By Rui Chen

My OS is Ubuntu 11.04, and the installed systemc is 2.2.0.

Here are the command lines to install the package:
1. Goto the OSCI website, and download the latest package.
2. Create a separate folder named /usr/local/systemc-2.2
3. Go seeking the cpp file with the directory like  systemc-2.2.0/src/sysc/utils/sc_utils_ids.cpp, and then add two statements into the file:

#include "string.h"
#include "cstdlib"
using namespace std;

4. Go to the systemc-2.2 folder, and type

xx/systemc-2.2.0/configure
sudo make
sudo make install

The separate installation folder can also avoid the name collision if installation conducted in the same folder.

Verification of the installation
The example file is adopted here(ref), while the command line doesn't work, even the echo $SYSTEMC_HOME didn't show the directory for systemc.
So, I change the command to the absolute address as shown below:


reference for running the systemc program

If we change all the addresses to the absolute ones, then we can make it. The final command lines are below:

export SYSTEMC=/home/chenrui/Desktop/llvm/systemc-2.2.0 # chenrui is my computer name, I have checked that the systemc.h is in the systemc-2.2.0 folder.
g++ -I $SYSTEMC/include -L $SYSTEMC/lib-linux -o example.o example.cpp -lsystemc -lm

Besides, I have also changed the line 2 of example.cpp so that I can find the systemc library.
And then, it is pretty sure that you can "Hello World." output.

What a wonderful day.
