Potrzebuję pomocy, próbując skompilować prosty przykład dla GLFW z MinGW

Question

Próbuję skompilować przykład z dokumentacji GLFW.

Moja struktura folderu dla bibliotek i plików źródłowych są:

C: \ CPP \

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

zawierać \

GLFW \

glfw3.h glfw3native.h

#include <GLFW/glfw3.h> 

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; 
} 

Próbuję skompilować go poleceniem

Answer 1

Kolejność, w jakiej znajduje się biblioteka w linii komend jest ważna dla gcc oraz ścieżek przeszukiwania biblioteki. Spróbuj przenieść -lglfw3 na koniec i dodaj bieżący katalog do ścieżki wyszukiwania, używając -L.

np.

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

Edit1: Od patrząc na wyjściu stanu opisowym, wydaje libglfw3.a że masz nie jest kompatybilny z gcc mingw używasz. Na szczęście linker ld może pracować z plikami DLL bezpośrednio. Zobacz, czy następujących prac:

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

Alternatywą byłoby utworzyć bibliotekę importu z glfw3.dll użyciu MinGW gcc, że masz. Jest to nieco bardziej skomplikowane, ponieważ trzeba utworzyć plik .def, a następnie wywołać dlltool.

Edycja2: Używany przez GCC mingw jest 64-bitowym kompilatorem Windows. Upewnij się, że używasz poprawnej 64-bitowej biblioteki glfw3 i , a nie wersji 32-bitowej. GLFW download section.

Answer 2

Myślę, że masz problem z nazewnictwem. Wygląda na to, że kompilator Mingw32 szuka plików biblioteki glfw3.dll, glfw3.a i glfw3.h. Problem polega na tym, że plik biblioteki ma nazwę libglfw3.a. Teraz musisz zmienić nazwę pliku na glfw3.a, aby mógł go znaleźć. Jeśli to nadal nie działa, musisz zmienić nazwę glfw3dll.a na glfw3.dll.a
