Problem Building project with Code::Block

[arashfahim]

Hi,
I am an absolute beginner in C++ and I installed full version of Code::Block in my Laptop. I tried to run the "Hello World!" program as the first program. I received the following error.

I tried to reinstall Code::Block, but it gave me the same error. I also tried to google the error but no success.

I appreciate you experts to help me remove the problem.

Thanks a lot

Did you re-install the Compiler?
If not, I suggest trying it.

[arashfahim]

Yes, I reinstalled it. I chose full installation. But, still  got the same error.

[ollydbg]

I tried to run the "Hello World!" program as the first program.

some suggestions:

1, give us the full steps how you create and build the "hello world" program.
2, the minimal sample code of the "hello world" program.
3, use .cpp (not .c).

I tried to run the "Hello World!" program as the first program.

some suggestions:

2, the minimal sample code of the "hello world" program.
3, use .cpp (not .c).

I did it in 2 ways.
First I created an empty file main.cpp. I put the following on the file:

#include<iostream>
using namespace std;

int main(){
    cout <<"Hello World!" << endl;
    return 0;
}

Then F9.
Second through New>Project>Console Application
choosing C++ and naming the project as test1. Then F9.

I took your advice. The file is called main.cpp not  .c. But the problem still exists.

[arashfahim]

I run the new  simple program:

using namespace std;

int main(){
     int a=2;
//    cout <<"Hello World!" << endl;
    return a;
}

It works perfectly. Therefore the problem should be in iostream.
Am I true? Should I add some path to compiler folder?

[ollydbg]

Should I add some path to compiler folder?

No, these folders were added by compiler by default.

I have no idea about other error.

BTW: you can put your project file in a folder WITHOUT a space in the folder path.

[arashfahim]

you can put your project file in a folder WITHOUT a space in the folder path.

It does not helped. Does anyone have any idea?

[stahta01]

If you have another MinGW in your system path, remove it.
If you have an MinGW in the folder x:\mingw for any drive letter in place of x rename or delete the MinGW folder.

Tim S.

[arashfahim]

Thanks Tim. I searched all the hard drive.  The only path is "C:\Program Files\CodeBlocks\MinGW". There is no other one. Did you mean that by system path?

[oBFusCATed]

no, he means the PATH environment variable

[arashfahim]

I checked this:
My Computer>System Properties>Advance [tab]> environment variables
Obviously there is no "C:program files/.../mingw" PATH in there. Should I add any. If yes which PATH. Because Code::Block has many folders one inside another, I can't figure out which one.

[Jenna]

If another installation is in system-path, it should be no problem (if the installation you use is complete), but if any of the disks has a \MinGW folder an installation in another folder might break.

[Jenna]

While compiling, C::B prepends the compilers bin dir to the path-variable (if your compiler installation dir is setup correctly in C::B).

[arashfahim]

Dear Jens,
How should I check if my compiler installation dir is setup correctly in C::B?
