gl.h included before glew.h? - c++

I've been getting this error "error C1189: gl.h included before glew.h" though my includes seem to be in the right order.
I also get a 9 warnings saying "warning C4005: 'APIENTRY' : macro redefinition"
I think it may be note worthy to say that I didn't get error before switching to GLFW 3, previously I was using GLFW 2. Below is the include at the top of my "Core.h".
//External Libraries
#include <GL/glew.h>
#define GLFW_INCLUDE_GLU
#include <GLFW/glfw3.h>
#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/type_ptr.hpp>
//Default Libraries
#include <cassert>
#include <stdexcept>
#include <cmath>
#include <list>
#include <iostream>
#include <string>
#include <sstream>
#include <windows.h>

I figured it out what seems to have happened is that I had a circular dependency which was also including glfw twice.

Visual Studio Professional 2013, Update 5, "No Target Architecture"

I have a CPP project in Visual Studio, I'm getting the following message when I try to build the solution:
1>c:\program files (x86)\windows kits\8.1\include\um\winnt.h(147): fatal error C1189: #error : "No Target Architecture"
The contents of stdafx.h:
#pragma once
#include "targetver.h"
#include <stdio.h>
#include <tchar.h>
#include <ctime>
#include <time.h>
#include <iostream>
#include <profileapi.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <Windows.h>
What's missing?
In the end I found that removing the headers:
profileapi.h
sys/types.h
Resolved the issue and the project now builds without warning or error.
Thank you Dai, the better solution:
#include "targetver.h"
#include <Windows.h>
#include <stdio.h>
#include <tchar.h>
#include <iostream>
#include <chrono>
#include <ctime>
#include <time.h>
#include <fstream>
#include <profileapi.h>
#include <sys/stat.h>
#include <sys/types.h>

reordering includes causes runtime error

One of my script file(.scnp)included the following headers as follows.
#include <stdio.h>
#include "kel.h"
#include "process.h"
#include "sigtypes.h"
#include "ScriptInterface.h"
#include "../saf/SAF_Scripts.h"
This type of header files include gives an error in GDB saying
"symbol lookup error: /xxx/xxxx.so: undefined symbol:
_Z16KEL_MEM_AllocateP19KEL_MEM_tPoolHandlej.
Included file after
#include <stdio.h>
#include "ScriptInterface.h"
#include "kel.h"
#include "process.h"
#include "sigtypes.h"
#include "../saf/SAF_Scripts.h"
ScriptInterface.h
extern "C"
{
#include "kel.h"
#include "process.h"
#if defined()
#include "sigtypes.h"
#endif
}
The scripts run successfully. What could be the problem? I have found the responsible method for this problem by using "c++filt" but don't know how to proceed further. Please help

Failure to recognize glMatrixMode() or GL_PROJECTION with all needed libraries given

I want to use OpenGL with C++ to create a basic scene with a "camera" (perspective) and an object to look at. I've found a sample code here. But for some reason, despite the fact that I've tied all the necessary includes and libs together (see below),
// OpenGL init and components:
#include <glload/gl_3_3.h>
#include <glload/gl_load.hpp>
#include <GL/glew.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/freeglut.h>
#include <excpt.h>
#include <glm/glm.hpp>
the IDE (Visual Studio Express 2012 for Windows Desktop) disagrees with me:
If you need more information of a certain kind, please let me know.
=============================================================================
Update: After some fiddling around with opengl-related files, this is what I came up with:
// Basics:
#include <windows.h>
#include <string>
#include <exception>
#include <stdexcept>
#include <stdio.h>
#include <stdlib.h>
// OpenGL init and components:
#include <glload/gl_3_1_comp.h>
#include <glload/gl_3_2_comp.h>
#include <glload/gl_3_3.h>
#include <glload/gl_4_0_comp.h>
#include <glload/gl_4_1_comp.h>
#include <glload/gl_4_2_comp.h>
#include <glload/gl_4_3_comp.h>
#include <glload/gl_4_4_comp.h>
#include <glload/gl_load.hpp>
#include <GL/glew.h>
#include <GL/freeglut.h>
#include <excpt.h>
#include <glm/glm.hpp>
And it tells me that GLEW_OK is undefined, albeit it's right there in glew.h:
#define GLEW_OK 0
I see that you're using glew, have you called glewInit()?
Also make sure you're checking if the initialization was a success.
GLenum err = glewInit();
if (GLEW_OK != err)
{
/* Problem: glewInit failed, something is seriously wrong. */
fprintf(stderr, "Error: %s\n", glewGetErrorString(err));
}
OR, It could be something like this
it happened to me this morning, a restart solved my problems

Compile errors when attempting to link <boost\property_tree\json_parser.hpp>

I have the following "includes" file in my project.
#pragma once
//glm
#include <glm\glm.hpp>
#include <glm\ext.hpp>
#include <glm\gtc\matrix_transform.hpp>
//glew
#include "GL\glew.h"
//glfw
#define GLFW_DLL
#include "GLFW\glfw3.h"
//libpng
#include <png.h>
//std
#include <stdio.h>
#include <vector>
#include <map>
#include <stack>
#include <queue>
#include <list>
#include <memory>
#include <iostream>
#include <fstream>
#include <assert.h>
//boost
#include <boost\filesystem.hpp>
#include <boost\property_tree\json_parser.hpp> /* problem */
//mandala
#include "types.h"
#include "type_traits.h"
#include "hash.h"
#include "macros.h"
When I include <boost\property_tree\json_parser.hpp>, I get many errors indicating that I'm redefining APIENTRY such as this one:
1>c:\program files (x86)\windows kits\8.0\include\shared\minwindef.h(130): warning C4005: 'APIENTRY' : macro redefinition
I'm perplexed as to why this is happening. I've tried to suppress the minwindef.h file from being processed by putting #define _MINWINDEF_ before the include statement but to no avail. Has anyone else encountered this or have any idea how I can properly include this boost library?
NOTE
Since youd did neither update your question to reflect the changes to the includes you made, nor provide the whole warning message, I can only guess:
You still have glfw.h included before the boost lib that includes the WinAPI header. Because when I just google for "APIENTRY redefinition", I get this SO question as first result, including the answer: Put the WinAPI header (or the boost header includign them) before the glfw.h include.
You may want to include also ptree.
#include <boost/property_tree/ptree.hpp>

sal.h not including when it is in Path

I'm working on implementing DirectSound into a program, but it requires dsound.h which requires sal.h, and for whatever reason I'm having trouble getting g++ to recognize the fact that I have sal.h and it is in the path file and I can even type in the direct command sal.h and command prompt will open sal.h. But when I compile with
g++-3 World.cpp -c
I get
dsound.h:13:17: sal.h: No such file or directory.
followed by thousands of errors from dsound.h resulting from the lack of sal.h. I'm just using notepad, g++, and command prompt, do I need to be in VC++ for sal.h to work? Is there any way to use DirectSound without it?
Here's the opening to the code I'm compiling, just in case:
#include "WorldEntity.h"
#include "MBox.h"
#include <D3D9.h>
#include <d3dx9.h>
#include <string>
#include <sstream>
#define _USE_MATH_DEFINES
#include <math.h>
#define KEYDOWN(vk_code)((GetAsyncKeyState(vk_code) & 0x8000) ? 1 : 0)
#define KEYUP(vk_code)((GetAsyncKeyState(vk_code) & 0x8000) ? 0 : 1)
using namespace std;
World::World()
{
//Etc
Here is the beginning of WorldEntity.h, the included file that includes dsound.h:
#ifndef WORLDENTITY_H
#define WORLDENTITY_H
class Entity;
class HUD;
#include "Enums.h"
#include "Object.h"
#include "Inventory.h"
#include "AI.h"
#include "Item.h"
#include "Sector.h"
#include "MBox.h"
#include "Particle.h"
#include "Sprite.h"
#include <windows.h>
#include <windows.h>
#include <mmsystem.h>
#include <mmreg.h>
#include <dsound.h>
#include <string>
#include <D3D9.h>
#include <d3dx9.h>
#include <cstdlib>
#include <ctime>
using namespace std;
enum FontIndex
{
//Etc
The command path is not the same as the include path. You have to add the -I flag to GCC to tell it where to find header files:
g++-3 -IC:\some\path World.cpp -c
