Prerequisite: SystemC installation
----------------------------------
- To compile SystemC you will obviously need a C++ compiler; if you still don't have it, on
Debian/Ubuntu platforms you may install all the required tools with the following command:
sudo apt-get install build-essential
- Download SystemC (currently at version 2.2.0) from
کد:
http://www.systemc.org/downloads/standards/
(a free registration is required).
- Unpack it; please note that some versions have a wrong file extension. For instance you may
have to use the following commands to untar it:
mv systemc-2.2.0.tgz systemc-2.2.0.tar
tar xvf systemc-2.2.0.tar
- Enter the newly created directory and refer to the file INSTALL which details all the steps
required for building. Basically they are:
mkdir objdir
cd objdir
export CXX=g++
../configure
make
make install
cd ..
rm -rf objdir
- With modern versions of GCC you may find the "make" command above to fail with the
following error message:
../../../../src/sysc/utils/sc_utils_ids.cpp: In function ‘int sc_core::initialize()’:
../../../../src/sysc/utils/sc_utils_ids.cpp:110: error: ‘getenv’ is not a member of ‘std’
../../../../src/sysc/utils/sc_utils_ids.cpp:111: error: ‘strcmp’ was not declared in this scope
make[3]: *** [sc_utils_ids.o] Error 1
make[3]: Leaving directory `/opt/systemc-2.2.0/objdir/src/sysc/utils'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/opt/systemc-2.2.0/objdir/src/sysc'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/opt/systemc-2.2.0/objdir/src'
make: *** [all-recursive] Error 1
If this is your case (for instance it happens while compiling SystemC 2.2.0 with GCC 4.4),
then please note that this is not a bug of the compiler but a bug in the SystemC sources,
because they have forgot a couple of include clauses.
To fix it, add the following includes at the top of file ../src/sysc/utils/sc_utils_ids.cpp :
#include <cstdlib>
#include <cstring>
You may even modify that file without using any text editor, just use this shell command
(yes, Fabrizio still loves UNIX shell!!!):
sed -i '1 i #include <cstdlib>\n#include <cstring>' ../src/sysc/utils/sc_utils_ids.cpp
Then restart from the "make" step in the list above.
Once you have installed SystemC correctly, you may then jump to the next step.
Build SystemC
-------------
If SystemC is installed correctly, then you just have to compile Noxim.
1) Extract the source files and go to the "bin" directory.
2) In that directory edit the file Makefile.defs (NOT Makefile.deps!) to modify
the "SYSTEMC" environment variable according to your SystemC installation path.
3) Just run "make".
You may ignore warning messages (if any), so if you don't get any error you are
ready to run Noxim for the first time using the command:
./noxim
If everything works fine, it is now safe for you to copy or move this executable
elsewhere; if you are a maniac of cleaning please note that "make clean" will
also delete the executable... so move it before cleaning!
