Use vcs to sim systemc file

My ubuntu is 10.04, the default g++ is 4.4. But for simulating systemc file, you need to specify the lower version of g++.

The problem can be solved as follows:
1.  Go to the archive link to download the following five files:
    gcc-3.4-base_3.4.6-6Ubuntu3_i386.deb、
    gcc-3.4_3.4.6-6Ubuntu3_i386.deb、
    cpp-3.4_3.4.6-6Ubuntu3_i386.deb、
    g++-3.4_3.4.6-6Ubuntu3_i386.deb、
    libstdc++6-dev_3.4.6-6Ubuntu3_i386.deb
Put them into the same folder, like g++-3.4, and then run command "dpkg -i *.deb";

2. redirect the g++ link to use the lower version
   You can find the g++-3.4 with find / -name g++-3.4* command, however, it is already inside the /usr/bin if you are familiar. All you need to do right now is to redirect the g++ to your newly installed file.
   The command is "ln -sf /usr/bin/g++-3.4 /usr/bin/g++";
   There is also another way, check the reference link(in Chinese)

With the user guide, the easiest way is to run simulations of your systemc file is :
   syscan adder.cpp
   syscan adder_tb.cpp adder_main.cpp
   vcs -sysc sc_main
   ./simv
