I'm using Code:Blocks 12.11 on windows 7, with the built-in MinGW compiler. When I try and compile a program that has an error in it (misnamed variable, missing include, extra semi-colon somewhere, anything) instead of saying something about what went wrong it just has this:
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings (0 minutes, 0 seconds)
Which is not particularly useful for debugging.
I'm making a game with the following class structure:
GameControl - The class that actually runs the game, with a while(!closed) // run the game loop.
State - A class that handles the state of the game, for example if the game is rendering the scene it would be in one state, and if it is rendering the menu, it would be in another.
ComponentManager - A class that manages all of the components of what is being done, for instance, the Scene class would contain a bunch of components handling the drawing of each tree, physics, the camera, etc. The manager will put them all together.
Component - A component of whatever is being done. A tree (and its rendering code) would be an example of a component of the scene. The camera would be another. The component does not necessarily have to be drawn, it could be handling something like physics (and would throw physics events to other components that need to move in a certain way).
The GameControl class has its loop, which would call the update function on the current State (there are classes that inherit State and override the update function of State).
In the update function of the base class "State", it would take all of the active ComponentManagers and update them. There are classes that inherit the base class ComponentManager and override its update function.
Each ComponentManager would update each of the Components that it owns.
This is the organizational structure that I came up with to make the game scalable and changeable . If, for instance, I wanted to add multiplayer at some point, I would add a class that inherits the State that controls the gameplay called "MultiplayerGameState". This would just add a new ComponentManager that inherits the ComponentManager that controls the player and all of the living things that are moving around. Then, the MultiplayerGameState class would recieve the multiplayer messages coming in and add other player Components for the other players.
My code is giving me various errors like "Forward definition of class State" and "Invalid use of incomplete type State". Unless I made some stupid error that I didn't catch, these are being caused by me including the classes in ways that some of the classes do not see the full definitions of the classes they need to see (because of the preprocessor directives preventing classes from being included multiple times.
Code: (Not implemented exactly as shown above, but I think the main difference is that the main class is not in GameControl, it's in OgreFramework.cpp)
The base classes: [URL] ...
States: [URL] ...
ComponentManagers: [URL] ...
Components: [URL] ...

My question is: is there a better way to implement my organizational system so that these errors don't occur?
I'm pretty new to C++ and I'm on Binary Trees in "Jumping into C++"! I've just created a DLL project on Code::Blocks, and I cannot get it to build and run: "You must select a host application to "run" a library..." is the message that I'm getting when I run the main code file. It's had no changes to it (except for a few extra, unnecessary line feeds), and it's the file which Code::Blocks generates on a DLL project.

1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
I've written a simple program that output's my name, course, and a time date stamp.
Having researched the code to do so, I've used the includes for both the ctime and time.h libraries.
I leveraged localtime_s and asctime_s to actually convert to string etc., and the program runs fine when I step through it in Visual Studio.
However, we're working with CGI and this program will ultimately be called up from the cgi-bin directory of a web server. The first thing that needs to be done after copying it to the webserver is to compile it. That's where my problem occurs.
Using the console command: g++ lab5a.cpp -o lab5a.exe the file is supposed to compile and be converted to a .exe.
However, instead I receive errors:
localtime_s was not declared in this scope
asctime_s was not declared in this scope
I "believe" it's because of the included libraries, but not sure.
They are:
HTML Code:
#include <iostream>
#include <ctime>
#include <time.h>
Here's the actual timestamp block of code:
HTML Code:
//Begin date and time instructions
time_t curTime;
struct tm locTime;
const int TimeStrLen = 26;
[Code] ....
Of course, I go on to error check and complete the block, but you get the picture.
When trying to compile, I am receiving errors which I am assuming are pretty generic and common:
lin_interp.c:21: error: expected '=', ',', ';', 'asm' or '__attribute__' before '{' token
lin_interp.c:100: error: expected '{' at end of input
I am just trying to get the code to work for now. I have created a program similar to this which worked in C++, but the code isn't jiving in C.
Code:
// Lin_Interp.c : Defines the entry point for the console application.
//
#include "PACRXPlc.h" /* Include file applicable for all targets */
#include "ctkInitCBlock.h"
#include "string.h"
#include "math.h"
#include "stdlib.h"
#include <time.h>
#include <ctype.h>
#include <stdio.h>
/* Constants / #defines */

What I'm doing wrong?
Visual c++ 2010 Express
Somehow the watch window is no longer shown in the debugger. It used to be available and I am stopped at a breakpoint.
Is there a way to turn it back on or restore it?
I'm doing an exercise that prints all input lines that are longer than 80 characters. I rather not use any libraries so I decided to write my own function that counts characters to use it in my main program. However when integrate things my function returns zero all the time.
Here is my full code:
/* Exercise 1-17 Write a program to print all input lines that are longer than 80 characters */
#include<stdio.h>
/* Declarations*/
#define MAX_STRING_LEN 1000
int count_characters(char S1[]);
int main() {
[Code] .....
So I was trying to debug my count_characters() function and this is the code if I was to run it seperately:
Code:
#include <stdio.h>
/* counts character of a string*/
main() {
int nc = 0;
int c;
for (nc = 0; (c = getchar()) != '
'; ++nc);
printf("Number of characters = %d
", nc);
}
which works...
I have programmed a game where you guess a number (1-6) and if the number is equal to the random number then give the player score + 10. But if I have selected for example 4 players then if the game will give player 1 a score it gives player 2 a score instead? What can be causing this error?
