How can I solve `glew32.dll is missing from your computer` issue of my OpenGL program? -


when i'm trying build , run opengl+glew+glfw program, builds fine wont run, giving me error : "the program can't start because glew32.dll missing computer. try reinstalling program fix problem."

i linking glew32.lib static library. using #define glew_static.

then, why program prompting dll file?

#include <iostream>  //#define glew_static  // glew #include <include/gl/glew.h>  // glfw #include <include/glfw/glfw3.h>  //we define glew_static, since we’re using static version of glew library. #define glew_static   // called whenever key pressed/released via glfw void key_callback(glfwwindow* window, int key, int scancode, int action, int mode) {     std::cout << key << std::endl;      if (key == glfw_key_escape && action == glfw_press)     {         //we close glfw setting windowshouldclose          //property true.         glfwsetwindowshouldclose(window, gl_true);     } }  // window dimensions const gluint width = 800, height = 600;  // main function, here start application , run game loop int main() {     std::cout << "starting glfw context, opengl 3.3" << std::endl;     // initializes glfw     glfwinit();     // set required options glfw     glfwwindowhint(glfw_context_version_major, 3);     glfwwindowhint(glfw_context_version_minor, 3);     glfwwindowhint(glfw_opengl_profile, glfw_opengl_core_profile);     glfwwindowhint(glfw_resizable, gl_false);      // create glfwwindow object can use glfw's functions     glfwwindow * window = glfwcreatewindow(width, height, "learnopengl", nullptr, nullptr);     glfwmakecontextcurrent(window);     if (window == null)     {         std::cout << "failed create glfw window" << std::endl;         glfwterminate();         return -1;     }      // set required callback functions     glfwsetkeycallback(window, key_callback);      // set true glew knows use modern approach retrieving function pointers , extensions     glewexperimental = gl_true;     // initialize glew setup opengl function pointers     if (glewinit() != glew_ok)     {         std::cout << "failed initialize glew" << std::endl;         return -1;     }          // define viewport dimensions     glviewport(0, 0, width, height);      // game loop     while (!glfwwindowshouldclose(window))     {         // check if events have been activiated (key pressed, mouse moved etc.) , call corresponding response functions         glfwpollevents();          // render         // clear colorbuffer         glclearcolor(0.2f, 0.3f, 0.3f, 1.0f);         glclear(gl_color_buffer_bit);          // swap screen buffers         glfwswapbuffers(window);     }      // terminate glfw, clearing resources allocated glfw.     glfwterminate();     return 0; }

i linking glew32.lib

that's went wrong, glew32.lib import library dll version. if don't want dependency on glew32.dll need link static link library. name glew32s.lib. defining glew_static otherwise has no effect on this.

guessing how have gone wrong, beware pre-built binaries available @ sourceforge include glew32.lib. you'll have build glew32s.lib yourself. in general pretty hard requirement, important use exact same compiler version , compiler options use build rest of code. read project's readme.txt file build instructions, had no trouble whatsoever building msvc provided project files.

the full list of library names:

  • glew32.lib: release build, requires glew32.dll
  • glew32d.lib: debug build, requires glew32d.dll
  • glew32s.lib: release build, static link library
  • glew32sd.lib: debug build, static link library

you can optionally build mx (multiple rendering context) versions of these libraries, "mx" appended names.

git - Possible to change Gitlab repository creation schema? -

my gitlab repos path set : data/git/repositories if user called superman creates new project gitlab automatically setup git repos path : data/git/repositories/superman/projectname does know can configure ? don't want have owners name in repos path. if want user's name in repository's path, set group project, , work against group's repository/ies. repositories lay in: /path/repositories/projectgroup/projectname thoug, gitlab somehow works github, each user has own personal repositories, can sync development branches , make merge requests group's repositories sets of commits, it's easier track modifications' ownership through forks. have @ tutorial such one how create , use it.
