J’ai besoin d’aide pour comstackr un exemple simple pour GLFW avec MinGW

J’essaie de comstackr un exemple à partir de la documentation de GLFW.

Ma structure de dossiers pour les bibliothèques et les fichiers source est la suivante:

C: \ cpp \

glfw3.dll glfw3dll.a libglfw3.a test.cpp

comprendre\

GLFW \

glfw3.h glfw3native.h

#include  int main(void) { GLFWwindow* window; /* Initialize the library */ if (!glfwInit()) return -1; /* Create a windowed mode window and its OpenGL context */ window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL); if (!window) { glfwTerminate(); return -1; } /* Make the window's context current */ glfwMakeContextCurrent(window); /* Loop until the user closes the window */ while (!glfwWindowShouldClose(window)) { /* Render here */ /* Swap front and back buffers */ glfwSwapBuffers(window); /* Poll for and process events */ glfwPollEvents(); } glfwTerminate(); return 0; }

J’essaie de le comstackr avec cette commande

 c:\cpp>x86_64-w64-mingw32-g++ -lglfw3 -Iinclude test.cpp -o test

mais j’ai cette erreur:

L’ordre dans -lglfw3 la bibliothèque apparaît dans la ligne de commande est important pour gcc ainsi que les chemins de recherche de la bibliothèque. Essayez de déplacer -lglfw3 à la fin et ajoutez le répertoire actuel au chemin de recherche en utilisant -L .

par exemple.

 g++ -Iinclude test.cpp -o test.exe -L . -lglfw3

Edit1: En regardant la sortie d’état verbeuse, il semble que libglfw3.a que vous possédez n’est pas compatible avec le mingw gcc que vous utilisez. Heureusement, l’éditeur de liens ld peut fonctionner directement avec les fichiers dll. Voir si les travaux suivants:

 g++ -Iinclude test.cpp -o test.exe .\glfw3.dll

L’alternative serait de créer une bibliothèque d’importation à partir de glfw3.dll utilisant mingw gcc que vous avez. Ceci est un peu plus .def car vous devez créer un fichier .def suivi d’un appel à dlltool.

Edit2: Le mingw gcc que vous utilisez est un compilateur Windows 64 bits. Assurez-vous que vous utilisez la bibliothèque glfw3 64 bits correcte et non la version 32 bits. Section de téléchargement GLFW .

Je pense que vous avez un problème de nommage. Il semble que le compilateur Mingw32 recherche les fichiers de bibliothèque glfw3.dll, glfw3.a et glfw3.h. Le problème est que votre fichier de bibliothèque s’appelle libglfw3.a. Maintenant, vous devez le renommer en glfw3.a pour qu’il puisse le trouver. Si cela ne fonctionne toujours pas, vous devez renommer glfw3dll.a en glfw3.dll.a
