Just started C++ yesterday...

[Leo Dragonheart]

I have a slight problem I can not get the following to work. What is wrong? Please help. I made the file executable and it looks like the same thing as on the screen they told me to put in....so what is up? Thanx for any help...

Copy the command you're using to compile and execute it.

You should be using:

g++ -Wall "C++ Practice~1" -o executable
chmod u+x executable
./executable

[StOoZ]

next time paste the code here , and not supply images like that.

I can barely see something.

Well that may be what is wrong. I just click the build button and then click build and run....:( I am using Code Blocks.

I am sorry. What do you mean past the code here? I was not using the terminal I was runing or trying to run it from code blocks...

You know what? completely drop the IDE. Open Gedit, add the bracket-matching, syntax highlighting and set the tabbing size to 4.

Grab gedit, write whatever you have to write, then open a terminal, go to the place where the file is and do


g++ -Wall "myfirstcode.cpp" -o executable
for compilation


chmod u+x executable
to make it executable


./executable
and running it.

Learn how to code, compile and run. Don't waste time on a fancy IDE, when the main objective is to learn a language. Later you can explore IDEs.

If it doesn't compile, you're probably lacking the compiling tools, which are easily attainable with:


sudo apt-get install build-essential

My first guess would be to remove that cin.get() statement and then try again.
[edit] actually scrap that your errors are on line three and five and your first is can't find using. Make sure build-essentials is installed.

Ok I will try what you suggest CAN+~, but I did only start C++ yesterday...Oh I forgot, Where is gedit?

I tried removing that like you said and I got permission denied this time.

I think to read this (I added the return line, otherwise the program is not correct)

#include <iostream>

using namespace std;

int main()
{
cout << "HEY, you I'm alive. Oh and Hello World!\n";
cin.get();
return 0; // main should always return an integer value
}


When I paste this in Code::Blocks it works, I guess either the build essentials package is not installed as Can + already suggested or Code::Blocks doesn point to GNU GCC compiler (in settings menu, compiler and debugger)

Yes I have build essentials 11.4 latest version...

I tried that same errors... Code Blocks does point to the GNU GCC compiler I think...

Believe us. You don't need an IDE till you get into a really complex project... It's usually much better to learn what the compiling process is by hand than clueless struggling against an IDE.

vim is what i use

[SledgeHammer_999]

How did you start the project in Code::Blocks? Maybe you chose "C project" instead of "C++ project" and codeblocks uses gcc instead of g++ to compile your source.

I totally agree with you all...I have completed 3 program tests and got them to work properly since this post a few hours ago. It is better to learn how to do it by hand first. I understand it way more now. Thx to everyone...;-)
