Installing systemc on Ubuntu

[Maryam]

Hi

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++

Seven cxx g++

It answers :command not found

Then I continued:

../configure

It took a moment and check 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?
