 Posted: Thu Dec 18, 2008 10:19 pm Post subject: Why Won't This Compile D: |
 |
|
Before I get flamed for asking a noob question or not knowing what the hell I'm doing, I want to say this is my first day trying to code C++ and I'm following a tutorial.
I'm using Visual C++ 2008 Express Edition, and this is what I'm trying to compile, or build:
| Code: | // This is a comment
// This program will accept numbers and display their sum
#include <iostream.h>
void main()
{
// define variables
float num1;
float num2;
float total;
// Enter data for the variables
cout << "Enter a value for the first variable: ";
cin >> num1;
cout << "Enter a value for the second variable: ";
cin >> num2;
// Add the two numbers together
total = num1 + num2;
// Display the result
cout << "The sum of the numbers = " << total
} |
My compile error is:
| Code: | 1>------ Build started: Project: Cpp1, Configuration: Debug Win32 ------
1>Embedding manifest...
1>mt.exe : general error c10100b1: Failed to load file "..\Debug\Cpp1.exe". The system cannot find the path specified.
1>Build log was saved at "file://c:\Documents and Settings\Krzysiu\My Documents\Visual Studio 2008\Projects\Cpp1\Cpp1\Debug\BuildLog.htm"
1>Cpp1 - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== |
Can anyone help me out? Google doesn't really help.

Maybe file is running, or is protected.
also add return 0; at end of main.

why would he add return 0; when main is type void.

What do you mean? Visual C++ 2008 Express Edition is running, but it won't compile. What do you mean the file is protected?

I don't think you've added the source file to your project correctly. If you were to create an empty project and build it, you will receive the same error. This would happen if you've created your source file using File -> New without adding it to the project.
On your left you should see the project name with 3 folders below (header, resource & source files), right click the source files folder -> add -> new item / or add your existing cpp file to the project.

| you dont need a return 0. Void means that the coder doesnt care about the return value. Anywho, EBO, close your Compiler, rerun, rebuild

His program isn't going to link because there is no int main. Change "void main" to "int main". Also, add a return 0 - it won't solve the problem (with no return, it will compile and leave eax as is, which will give it some random return value) but it is a good idea.

I make a project called Demo1 as a Empty Project.
Then I make a new file, put the code in, then save it as Demo1.
I press Build, then Build Demo1.
And I get that error over and over. And it's not a coding error, I just don't think I'm creating the workspace or whatever you want to call it the right way.

using "void main" which should be "int main" is the main function in c++
void int isent allowed in some c++ compilers and some big company's so it is incorrect
the main function should always look like this
int main() {return X;}
ontopic
delete the "debug" folder and try compile it again
if you cant delete it restart your computer and try again (press rebuild all)

ok weird i mean it should be able to find the file it just created
it look like it is protected or already running or something idk really
well you could try this too
go to C:\windows\prefetch and delete everything in it
then try to compile your file again
idk why but thats a common problem for me and some other i know (happening often when you try to inject some dll into something and application crashes)

So there's no fix?
Would another IDE fix it? The tutorial I'm following is using Visual C++ 6.
What's the 'best' for newbies out there?
EDIT: Forgot to say, after I deleted everything in the prefetch folder, it still didn't work.

After you've made an empty project, how are you creating the new source file? Can you upload a screenshot of the IDE with your project open or upload the project itself?
