I am trying to compile an OpenGL program.
This is the portion of the code with all the includes:
#include <stdio.h>
#include <assert.h>
#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glut.h>
// Usage of degrees is deprecated. Use radians for glm functions.
#define GLM_FORCE_RADIANS
#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include "shaders.h"
The file i am trying to run is called mytest1.cpp and i also have shaders.h in the same directory.
In the same directory i have a folder called 'include' And inside two subfolders called 'GL' and 'glm' with all the files inside that are required from the program.
So i go to the directory of the mytest1.cpp and i type g++ mytest1.cpp and i get the error:
mytest1.cpp:14:21: fatal error: GL/glew.h: No such file or directory
#include <GL/glew.h>
^
compilation terminated.
Why does this happen? I also tried to place the 'GL' folder in the root directory and i got the same error

I am using MinGW compiler with the command line and sublime text 3. While including the header files for DirectX into my C++ code, it gave errors saying they weren't found.
#include <windows.h>
#include <windowsx.h>
#include <d3d11.h>
#include <d3dx11.h>
#include <d3dx10.h>
This results in the following error:
lesson 5.cpp:4:20: fatal error: d3dx11.h: No such file or directory
#include <d3dx11.h>
If I comment out the line it gave an error for, it just gives the same error for the next line.
I'm having a strange linking issue after I included inotify in my program to monitor changes to a filesystem. The project includes <fcntl.h> in many other source files. However, when I include <sys/inotify.h> in the source file which is doing the directory monitoring, I get this error:
/usr/include/fcntl.h:30:1: error: expected initializer before ‘extern’
__BEGIN_DECLS
My project uses CMake, although that doesn't seem to be relevant for finding inotify. It IS finding the inotify declarations to my knowledge, since when I included , it threw an error that inotify_init() and the other functions I used were not defined. Inotify includes fcntl and is partially built on top of some of the functionality there, so my first thought was that it's importing a different version of fcntl than the rest of my program.
In ObjectManager.h:
#ifndef MANAGE_OBJECT_H
#define MANAGE_OBJECT_H
#include "config.h"
//includes all lua headers under extern 'C'
#include <lua.hpp>
#include <list>
#include <unordered_map>
#include <pthread.h>
class ObjectManager //...
The only thing that changed was ObjectManager.cc, with the addition of sys/notify and the implementation of the watcher (not included because this is a linking issue):
#include "config.h"
#include "ObjectManager.h"
#include "Control.h"
#ifdef OBJECT_MANAGER_ENABLED
#include <string.h>
#include <stdio.h>
#include <dirent.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <vector>
#include <unistd.h>
#include <fstream>
#include <sys/inotify.h>
//... inotify implementation
Where Control.h declares #include <fcntl.h>.
This is the closest issue I found, related to some problems in the implementation of different fcntl headers for userspace usage. https://lkml.org/lkml/2008/9/16/98
The same problem occurs on Linux 2.6 running on Centos 6 and Linux 4.0 running on Centos 7.
Any ideas on what is causing this error and how to successfully include inotify?
Resolution: A function definition lacked a semicolon at the END of ObjectManager.h right before a #endif, and the resulting GCC error that propagated through the next includes in a complicated manner, resulting in a strange preprocessor error in fcntl.h.
I have been unable to compile a basic class file to generate a window using SDL2, using both brew and compiling from the SDL site using using...
#include <SDL2/SDL.h>
at the top of the file.
Have also used...
#include <SDL/SDL.h>
#include "SDL"
among others and nearly always get this error
./src/window.cpp:1:10: fatal error: 'SDL2/SDL.h' file not found
#include <SDL2/SDL.h>
Something should have worked and just hasn't.
I get the compiler error __declspec(align('16')) won't be aligned.
When I click the error, Visual Studio sends me to GLM_IMPLEMENT_SCAL_MULT(vec4), which is on the scalar_multiplication.hpp file.
What is the cause for this compiler error? How can I fix it?
Note: Could it be some kind of conflict with the includes? I have several includes in a header file. The commented one is the one that gives the error.
// OpenGL Math library
#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/type_ptr.hpp>
//#include "glm/ext.hpp" // For printing matrices
#include <SFML/Graphics.hpp>
#include <GL/glew.h>
I'm trying to use Boost's Dynamic_bitset class for a project, and I (believe I) have taken whichever subset of files I needed from the complete library. Now I'm doing an
#include "boost/dynamic_bitset.hpp" inside my manager.cpp file, and when compiling I get this:
In file included from manager.cpp:4:0:
boost/dynamic_bitset.hpp:15:51: fatal error: boost/dynamic_bitset/dynamic_bitset.hpp: No such file or directory

This same project compiles fine on my university's linux systems(g++ 4.2.4 there but I doubt it matters), but fails to do so (with the above error) on my Ubuntu laptop. Why isn't it finding the file since it evidently exists?
All my includes are as such:
#include <cstdlib>
#include <cstdio>
#include <iostream>
#include "boost/dynamic_bitset.hpp"
#include <cmath>
#include <list>
#include <unistd.h>
#include <sys/sem.h>
#include <sys/shm.h>
#include <errno.h>
#include <wait.h>
#include <time.h>
#include "extras.h"
compilation is done simply with
g++ -o manager manager.c
or
g++ -Iboost -o manager manager.c
if I want to explicitely include the (local..) folder
-I .
At least if you are compiling in the same directory that contains boost.
You wrote -Iboost and #include "boost/…". So it looks in ./boost if there is a boost subdirectory.
