installing systemc on ubuntu

Question

I am a beginner. I'm installing systemc231 on Ubuntu and I have done this:

tar -xzvf systemc-2.3.1.tgz
cd systemc-2.3.1
sudo mkdir /usr/local/systemc231
mkdir objdir
cd objdir
export cxx="<compiler>"
export cxx=g++
export cxx=clang++
setevn cxx g++

It answered :command not found Then I continued:

../configure

It took a moment and checked something but finally it answered :

 Configure:error: in /home/Ubuntu/systemc-2.3.1/objdir':

 Configure:error:c++compiler cannot create executables see 'config.log' for more details

And then I continued :

make

And it answered :

make:*** no targets specified no makefile found. Stop.

Now what can l do? This is the link of systemc231 file and I have used its readme and install files for writing the commands :

It seems that you mess up everything. Which tutorial you followed ? can you attach the link with the question ? — orvi, Aug 22 '15 at 08:35

command not found: setevn cxx g++ => setenv cxx g++ (small typo in setenv) — vermaete, Aug 23 '15 at 13:32
Could you try just the command 'g++' to find out if you have the GNU C++ compiler installed? You can do the same for 'clang++' — vermaete, Aug 24 '15 at 06:46
Thank you all, now I have an error that is 'compiler not supported '.how can I fix this? — maryam, Aug 24 '15 at 11:47
time for an update of your commands. What is the last 'export CXX' you have done. And what about running that command itself. — vermaete, Aug 25 '15 at 07:08
you are right vemaete, I have followed your instruction, I used the command 'g++' and I found out that I have the GNU C++ compiler installed. I have tried systemc220, systemc230 and systemc231. — maryam, Aug 25 '15 at 07:52
I think may be I have not downloaded all the necessary software, don't you think so? — maryam, Aug 25 '15 at 07:57
should it not be 'export CXX=g++' (capitals). Don't do another export!. And check with 'env | grep CXX' if the variable is set. — vermaete, Aug 25 '15 at 09:43
thank again, the problem was solved. now after' make' I see these messages: — maryam, Aug 25 '15 at 16:48
../../../libtool: line 1153: g++: command not found make[3]: *** [sc_attribute.lo] Error 1 make[3]: Leaving directory `/home/ubuntu/Downloads/systemc-2.3.0/objdir/src/sysc/kernel' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/ubuntu/Downloads/systemc-2.3.0/objdir/src/sysc' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/ubuntu/Downloads/systemc-2.3.0/objdir/src' make: *** [all-recursive] Error 1 — maryam, Aug 25 '15 at 16:57

In Ubuntu, you use export to set environmental variables. In other Linux distributions, you use setenv. You only need one of those commands. do a command to figure out if g++ is installed

which g++

If it doesnt return something like

/usr/bin/g++

Then its not installed, just install it with

sudo apt-get install build-essential

then check again with which You created an installation directory /usr/local/systemc231 you need to specify that you want to install systemc therein in the configure command. Find a tutorial about setting up systemc and eclipse configuration in ubuntu on my blog
