glfw

问题 So im using GLFW and the following method works when called in my main method void Display::run() { while (!glfwWindowShouldClose(window)) { /* Render here */ /* Swap Buffers And Poll */ glfwSwapBuffers(window); glfwPollEvents(); } } but when i try to run it on a separate thread i get a segfault std::thread t1(&Display::run, this); any ideas? ask if you want any more of the code Edit: main.cpp #include "src/support/Display.h" int main() { Display* d; d->start(); return 0; } Display.h #include

问题 It seems to be platform related (works with Ubuntu 12.04 on my laptop, doesn't work with another Ubuntu 12.04 on my workstation). This is a sample code about what I am doing with two threads. #include <iostream> #include <thread> #include <chrono> #include <atomic> #include <GL/glfw.h> using namespace std; int main() { atomic_bool g_run(true); string s; thread t([&]() { cout << "init" << endl; if (!glfwInit()) { cerr << "Failed to initialize GLFW." << endl; abort(); } glfwOpenWindowHint(GLFW

I really prefer GLFW to Glut and want to get its Golang binding working under Windows 64-bit with

问题 So, I am trying to set the window icon for my glfw window (obviously) but I am having trouble doing so because I don't know how to set an icon using GLFWimage. The code in the docs is as shown: GLFWimage images[2]; images[0] = load_icon("my_icon.png"); images[1] = load_icon("my_icon_small.png"); glfwSetWindowIcon(window, 2, images); But there, it doesn't show how to use or create a "load_icon" function. So, can anyone help cause I have been searching for months. 回答1: glfwSetWindowIcon

问题 I've compiled glfw3 and the included examples using cmake and make without problems. Onto writing my first project. Being new to opengl and glfw, and unexperienced with C and CMake, i'm struggling to understand the example build files, or even which libraries to link and/or compiler parameters to use in my project. Let's say i have just one folder with one file, boing.c for now. How would i compile it? Simply running gcc -lglfw3 -lm -lGL -lGLU boing.c gives a wall of undefined references,

问题 I've been all over the internet and I simply cannot find a way to install GLFW for OSX and use it with Xcode. A lot of articles use cmake for this, which I tried to install but I still can't access it from the terminal. I just need a simple step-by-step guide for installing it because I'm going to lose my mind. Thanks 回答1: I use homebrew to install GLFW. Once brew has been configured, use the commands brew tap homebrew/versions brew install --build-bottle --static glfw2 回答2: If you are still

问题 I have been programming in C for a while, but now I come to GLFW and OpenGL and everything goes wrong. I am using OSX Snow Leopard and XCode, compiling with GCC. I added to the project the following frameworks to be sure everything is there : Cocoa, OpenGL, GLUT, AGL and Carbon. Under XCode, I put under the Header search paths: /usr/local/include And I put under the Library search paths : /usr/local/lib , /usr/local/lib/pkgconfig and /Users/Arkady/Desktop/glfw-2.7.2/lib (I know it is probably

问题 I am pretty new to OpenGL and have a simple program that I am messing with at the moment. The issue that I am running into is when I pass an array to represent the color of points, the color just ends up being black. It works fine if I just explicitly define a color in the fragment shader, and if I switch the indices of the data in the VAO, the triangle is moved to the points that are the colors. I tried using API trace and got the following: 6872: message: major api error 1282: GL_INVALID

问题 I'm trying to get OpenGL to work with Python. I'm using a python binding of glfw to display the window/configure the keyboard and such. The Sourceforge page for pyglfw has a download link containing a .pyd file and a dll. On the git page, pyglfw contains a bunch of folders. I downloaded both, and referenced them with PyDev in Eclipse, in the Eclipse "External Libraries" section. I wrote some code: import glfw glfw.Init(); if (glfw.OpenWindow(800, 600, 5, 6, 5, 0, 8, 0, glfw.FULLSCREEN) !=

问题 If I call long rslt = glfwGetPrimaryMonitor(); the result is 0. The glfw library can't pick up my monitors for some unknown reason. Also, if I try: PointerBuffer rslt = glfwGetMonitors(); the result is null... My monitors work fine. I have seen some suggestions that I should uninstall my monitors and let windows reinstall the appropriate drivers. This seems like an inadequate workaround to me. I can't expect users to have to do this if they run my application. I'd much prefer to at least get
