C++ :: OpenGL Test Code With GLFW And GLEW Compile Errors
Jul 7, 2013
I'm learning OpenGL 3.2+ with GLFW and GLEW.
I'm learning it through this series of tutorials [URL] but when I run the first code:
#include <iostream>
#include <cstdlib>
#include <GL/glfw.h>
#define GLEW_STATIC
#include <GL/glew.h>
int main() {
glfwInit();
glewExperimental = GL_TRUE;
[code]....
(Then i have the glew.h that is about 17000 lines of code)
I get this errors:
c:archivos de programacodeblocksmingwin..libgccmingw324.7.1........includeGLglew.h|84|error: #error gl.h included before glew.h|
c:archivos de programacodeblocksmingwin..libgccmingw324.7.1........includeGLglew.h|1793|error: 'GLchar' does not name a type|
c:archivos de programacodeblocksmingwin..libgccmingw324.7.1........includeGLglew.h|1804|error: 'GLchar' has not been declared|
[code]....
What I'm doing wrong?

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 */
// Print-Out on console "XY LIMIT ARRAY" XYlim

I downloaded glew 1.9.0 files and dragged the lib, include, and bin of the glew into the mingw folder within Code Blocks. I don't know if this is the right thing to do I don't understand how this stuff works. Anyway, I tried to compile my openGL 3.0 program that uses glew and I got this error: The procedure entry point _glewBindArray could not be located in the dynamic link library glew32.dll, How do I install glew properly?

I'm working on a Hash Table implementation and after fixing all the errors and finally getting it to compile and link correctly, I am met with a black screen upon execute.
main.cpp
#include <stdio.h>
#include <string.h>
[Code]....
I tried inserting a debug statement in the main() function to see, and it wouldn't even print out the message "debug me" on the screen.
I am using Code::Blocks on Windows with the mingw32-g++.exe compiler. Here is my build log:
mingw32-g++.exe -Wall -g -c D:MediaDesktopHashElement.cpp -o objDebugElement.o
mingw32-g++.exe -Wall -g -c D:MediaDesktopHashHashTab.cpp -o objDebugHashTab.o
mingw32-g++.exe -Wall -g -c D:MediaDesktopHashmain.cpp -o objDebugmain.o
mingw32-g++.exe -Wall -g -c D:MediaDesktopHashStudent.cpp -o objDebugStudent.o
mingw32-g++.exe -o binDebugHash.exe objDebugElement.o
objDebugHashTab.o objDebugmain.o objDebugStudent.o -mwindows

Here's the source code from "battle.h" (which should probably be renamed to "animal.h")
Do you think I made my errors here or in one of the many other headers or cpp?
#include "Identity.h"
#include "stdafx.h"
#ifndef battle_h
#define battle_h
int numbers1 = rand() % 5;
int numbers2 = rand() % 7;
int numbers3 = rand() % 9;
int numbers4 = rand() % 11;

I'm making a program to draw a trajectory, was using as a basis the tangent, but when I put 90 degrees, the tangent is very large, so I thought of putting an if (angle == 90) did not use the tangent.
the design is right, but after choosing it 90 degrees it stops to draw.
for example
1-30 degrees - draws
2-45 degrees ---- draws
3 draws -90 degrees ---
4-60 degrees --- not drawing
5 --- 80 degrees --- not drawing
*
*
making routine design is presented below:
void Draw() {
glColor3f(1.0, 1.0, 1.0);
glBegin(GL_LINES);
convert(graus);
if (ant){
x=xx;
y=yy;

- When I need to code something, what is the process I should go through to design any algorithm(s), and solve the problem in the most efficient/flexible way? At the moment, I just think up a way of solving it and if it works I will use the code in my current project, but as I have found out from some of my larger projects, this definitely is not the way to go!
- How can I criticize my own code? Again, if I write some code that works I'll keep it. Go through the code and look out for optimizations or refactor the code? Which leads to my last question...
- How can I test my code for efficiency? What are the best ways of testing algorithms (etc) that I have added to see if they are fast enough? Of course, it will probably involve some kind of timer, but how will I be able to tell if X milliseconds is a good enough time?

I want to start developing Android apps in C++, but I do not know what I could use to compile the source code into an apk. I know that C++ is probably not the best choice for Android development, but I already know it and I do not want to learn Java.

I recently downloaded the ' code:blocks ' file. After I tried some code the compiler stated there was an error with
' #include<iostream> '.
Since I'm not a C++ programmer, right now, I'm confused. This was copied directly from the e-book I downloaded. After I uninstalled this program, I re downloaded it and now it comes up with a new error while opening Code-blocks.
This new error states ' Can't find compiler executable in your configured search path's for GNU GCC compiler '

i use cygwin and i have a program that was returning an error saying "undefined reference" and i figured out that i misspelled a word. how can i search for the misspelling in the input mode, if ive just completed a very large program and dont want to scroll through possibly 300+ lines of input? im not totally out the loop, but i know i can "vim program.cpp" to open the program, but before clicking "i" to actually edit, there must be a way to search a word

I'm currently just trying C++ with SFML. So I've installe SFML 2.0 for Visual C++ 2010 Express 64 bit, and I get an error while trying to run the debug of my code.
//Libraries
#include <SFML/Graphics.hpp>
#include <iostream>
int main() {
sf::RenderWindow window(sf::VideoMode(1280, 720),"SFML Game1");
return 0;
}
And this is the result I'm getting when trying to run it

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.

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 believe I set up everything correctly. I linked the library folder, the includes, and included the libraries needed. It still comes up with an error that it can't find the functions or something like that.
The error:
Do I need to include the DLL some way? I tried adding it to the build directory and the EXE directory, but it did not work. My code is just a small test.
#include <GLFW/glfw3.h>
#include <cstdio>
#include <cstdlib>
int main() {
if (glfwInit() == false) {

This is my first time using opengl and I am experimenting with adding/drawing polygons/points/etc. on top of a PPM image. The image is already loaded when the application runs. My attempt to draw a square is from lines 30 - 35. The program runs but the square is not present. Just the image.
#include<windows.h>
#include <stdio.h>
#include <stdlib.h>
#include<Gl/gl.h>
#include<GL/glut.h>
int n;
int m;
int *image;

I've read up on .bmp files on wikipedia and am currently attempting to make a function that can export a .bmp file of the screen of my programs. I've already begun work on it but it isn't working. The code I have so far is:
typedef char Byte;
typedef int Byte4;
typedef short Byte2;
struct BMP_Header {
[Code] ....
My problems are that when less then the required amount of bytes is needed to store a value in the file, the 00 bytes are skipped (Ex. The file will contain 42 instead of 42 00 00 00), and the Pixels are stored as nothing but 0D ( every value intended for storing pixel data is 0D ).

I don't know why, but textures in OpenGL are white. One day, I must've change something, and now my textures wont load properly. I tried rewriting my code that loads things multiple times, my textures still are white. Here is my code:
(I switched back to the FF pipeline temporarily, in my other projects I use shaders.)
Sprite.hpp
#include <SDL.h>
#include <SDL_opengl.h>
#include <fstream>
#include <iostream>
#include <string>
#include <vector>
#ifndef _SPRITE_H_
#define _SPRITE_H_
[Code] ....
