Unable to compile using g++

[Rudipoo]

Hi all,

I'm relatively new to Linux and programming. I am using Knoppix version 6.2.1 but cannot seem to compile a simple program to add two numbers together. The source code was written in a leafpad document and named "SimpleAdder.cc". I saved this to a directory called ~/c++ . In the terminal I changed to this directory then typed "g++ SimpleAdder.cc -o SimpleAdder". The terminal returned

"bash: g++: command not found"

Can anyone help me figure where I went wrong? (I also tried "make SimpleAdder" while in the same directory but only got "make: g++: command not found" and "make: *** [SimpleAdder] Error 127".

Thanks in advance

I have just thoughts; maybe the CD version of Knoppix 6.2.1 which I am using doesn't have a C++ compiler?

I seem to be having the same issues...see my thread below yours.

Maybe we need the dvd version of knoppix.

Seems like you don't have g++ installed. I don't know much about Knoppix, I have tried it briefly some time, but I guess you have some kind of package manager of some kind where you can search for software and install it with a few clicks.

"bash: g++: command not found"

Open a terminal window and type the following:

  $ sudo apt-get install build-essential

This will install the essential packages you need to compile basic things, including the GNU C++ compiler g++.

[Rudipoo]

I'm afraid your hint didn't work unlimitedscolobb; after saying

Reading package lists... Done
Building dependancy tree
Reading state information... Done

the terminal reads

E: couldn't find package build-essential

So, any other suggestions? Is it certain that the cd version has a c++ compiler?

Thanks

[unlimitedscolobb]

E: couldn't find package build-essential

Hm. Could you please do:

  $ sudo apt-get update
  $ sudo apt-get install build-essential

You may have an empty or incomplete list of packages; running the update command should solve this.

If doesn't work either, will you please tell us the output of the following:

  $ cat /etc/apt/sources.list

This will tell us which repositories is your apt told to fetch packages from. Although I am inclined to find it unlikely, this list may be incomplete or empty.

Is it certain that the cd version has a c++ compiler?

Please note that I am not trying out the commands I suggest within a Knoppix LiveCD environment, but I cannot see any reason for a C++ compiler not to be accessible from this environment. I may be wrong, however

Hey, thanks for your help. It was all going great (did the update, then did the build-essential), and everything seemed to be installed correctly. Then I tried a simple HelloWorld program. Here is a sample of the error messages:

Any thoughts? Thanks again

Will you please post the source code of your program here?
