glfw

As my hunt for a cross-platform framework/library went in progress, GLFW was mentioned many times. So, I decided to try it out. Now, it seems as though I can't even init a window. :-/ #include #include #include int main(int argc, char *argv[]) { int running = GL_TRUE; srand(time(NULL)); if (!glfwInit()) exit(EXIT_FAILURE); if (!glfwOpenWindow(300, 300, 0, 0, 0, 0, 0, 0, GLFW_WINDOW)) { glfwTerminate(); exit(EXIT_FAILURE); } while (running) { glClear(GL_COLOR_BUFFER_BIT); glClearColor(rand() % 255 + 1, rand() % 255 + 1, rand() % 255 + 1, 0); glfwSwapBuffers(); running = !glfwGetKey(GLFW_KEY_ESC

Having a minimal example using GLFW3 : #include <GLFW/glfw3.h> int main(int argc, const char * argv[]) { glfwInit(); } ...results in a ton of linker errors: (small excerpt) Undefined symbols for architecture x86_64: "_CFArrayAppendValue", referenced from: _addJoystickElement in libglfw3.a(cocoa_joystick.m.o) "_CFArrayApplyFunction", referenced from: __glfwInitJoysticks in libglfw3.a(cocoa_joystick.m.o) _addJoystickElement in libglfw3.a(cocoa_joystick.m.o) "_CFArrayCreateMutable", referenced from: __glfwInitJoysticks in libglfw3.a(cocoa_joystick.m.o) ...

I recently had to reinstall Linux Mint on my PC. I reinstalled all my libraries, such as GLFW and came across an error I have never seen before. Unfortunately my google-fu skills do not seem up to par for this error as I've not been able to find any fixes that work for me. Sidenote: these programs compiled fine on my old installation, and they also compile perfectly fine on my laptop that also runs Linux Mint 17.2. This is the compile statement I using to compile: g++ -std=c++11 main.cpp -o out -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi This is what the terminal spits out at me

Why is it that some static libraries (lib*.a) can be linked in the same way that shared libraries (lib*.so) are linked (ld -l switch), but some can not? I had always been taught that all libraries, static or not, can be linked with -l..., however I've run into one library so far (GLFW), which does nothing but spew "undefined reference" link errors if I attempt to link it this way. According to the response on this question , the "proper" way to link static libraries is to include them directly, along with my own object files, rather than using -l. And, in the case of the GLFW library, this

I am trying to develop an openGL application with GLEW and GLFW on Windows using minGW. In the current directory, project/ , I have the directories src/ , bin/ , and glfw-3.0.4.bin.WIN64/ . I have the files test.cpp , glew.h , glew.c , and wglew.h in the src/ directory. The directory ./glfw-3.0.4.bin.WIN64/include/ contains the GLFW/glfw3.h header file. The directory ./glfw-3.0.4.bin.WIN64/lib-mingw/ contains glfw3.dll , glfw3dll.a , and libglfw3.a . My main file, test.cpp contains, #include "glew.h" #include "GLFW/glfw3.h" #include <stdio.h> int main(int argc, char** argv) { printf("Hello,

准备事项 编译器 ：装有c++组件包的visual studio 2019 GLFW ：在 GLFW下载地址 中下载32位的Windows预编译二进制文件 GLEW :在 GLEW下载地址 中直接点击下载glew文件即可 做完上述步骤后，我们会得到两个压缩包，把压缩包的文件放在同一个文件夹中，进行下一步。 项目配置 打开vs2019，创建一个c++空项目，命名为OpenGL_Template，创建一个main.cpp文件，以后的项目可以以此项目为模板，就不用重新配置环境。 include文件配置 打开项目->OpenGL_Template属性->C/C+±>常规->附加包含目录->编辑 选中glew文件夹的include和glfw文件夹的include lib文件配置 项目->OpenGL_Template属性->链接器->常规->附加库目录 跟上面同样的操作，把glew和glfw的lib配置好 注意glew的lib要选择glew-2.1.0\lib\Release\Win32，64位的文件会有bug glfw的lib根据编译器版本决定，这里使用vs2019，所以选择lib-vc2019 这一步配置好的效果 最后一步 项目->OpenGL_Template属性->链接器->常规->输入 手动输入opengl32.lib、glfw3.lib、glew32s.lib
