Hello, i want to build a program with MinGW32 which have three files, one called main.cpp (where glewInit() is called), other called Shader.cpp and their header Shader.hpp . 4 comments. I think I'm supposed to link in a lib file to get rid of these undefined references but I'm not sure what the filenames are that I need to link in. If you get undefined reference to glWindowPos2i you may have an old GL library. If you try to run the application now and it gives a lot of undefined reference errors it means you didn't successfully link the GLFW library. Good stuff. Thank you lots for your help! GLFW is no exception. (Path has been shortened for easier reading) The first command compiles the .cpp into a .o successfully, but the second command gives me errors from the linker.

I know that I have to link. share. 如果你现在编译你的cpp文件会得到大量的 undefined reference (未定义的引用)错误，也就是说你并未顺利地链接GLFW库。 注意：请确认您的系统支持OpenGL3.3或更高版本，否则此应用有可能会崩溃或者出现不可预知的错误。 GLFWAPI void glfwWindowHint(int hint, int value); GLFWAPI void glfwWindowHintString(int hint, const char* value); 设置window的hints值，在glfwCreatewindow时生效，设置之后不会改变，知道遇到函数glfwDefaultWindowHints或GLFW终止。这个函数只能设置整形值，字符串的值通过glfwWindowHintString来设置。 If you get undefined reference to glWindowPos2i you may have an old GL library. The projects hirachy. Je viens d'essayer et mon problème n' a toujours pas changer. save. Je viens d'essayer et mon problème n' a toujours pas changer. My CMake file looks more or less like this: New comments cannot be posted and votes cannot be cast. I just started to program with glfw.

I startet with Qt and tried a simple example usind glew and glfw libraries, but I get "undefined reference" errors for every glfw command. Après des bidoullage sur les linkers compléter avec des recherches sur internet, j'ai enfin réussi à compiler, mais il est vrai que je ne sais pas trop comment j'ai fait ^^' It seems every time I try to set one up, even if I follow the instructions to the letter, something goes wrong, I search Google, try a solution that supposedly is supposed to fix it, it doesn't work, repeat, and eventually give up. Here is the code I'm using and to compile I'm using this command (I'm following the tutorial as it's written) g++ -std=c++11 -o main -lglfw -lGLEW -lGL main.cpp. I'm using 32-bit MinGW in Code Blocks on .

This is my compile/link log when I use g++ -o helloGL helloGL.cpp -lGLEW -lglfw3 -lGL -lX11 -std=c++11: Could someone walk me through how to properly link this? And I don't know why should I make a separate .cpp file to separate a few functions, when you already put tons of inline functions in header. GLFW is no exception. So today I would like to explore a GLFW and Dear ImGui combo. If in compiling the example programs you get errors referencing, for example, glBindFrameBufferor similar functions, you may not have support for Make sure that you define -DUSEGLEW on the compile line so that you have a newer version of OpenGL. 30 juillet 2017 à 22:14:21. 该命令: g++ -I<path to headers> Tma.cpp -L<path to libraries> -lglu32 -lopengl32 -lglfw3 -lglew32 在Windows中还不够。您将需要链接其他系统库。 ( 0 AppKit 0x00007fff9710b9a4 - [NSWindow . 说明: 本文旨在通过配置网页 修改 网关的配置文件 最后效果是 1---打开网页 可以显示文件JS中的数值 1--打对勾 0--不打对勾 2---点击红色按键 可以保存上面的打勾情况到本地文件 也就是修改JS文件 第一步修改html --直接展示UI 最后追加如下内容 第二步修改config .

If you get undefined reference to glWindowPos2i you may have an old GL library. However, if I remove both Shader.cpp and Shader.hpp the program is builted and i dont get problems. function findundef() { [ -z "$1" ] || [ -z "$2" ] && { echo "usage: findundef . EDIT: The most confusing thing now is that I can include GL/gl.h, I can call gl things, but it still tells me that package gl was . There will be also a silly SDL vs GLFW comparison.

GLFW is almost the same thing as SDL - a way to create windows and OpenGL contexts. If in compiling the example programs you get errors referencing, for example, glBindFrameBuffer or similar functions, you may not have support for OpenGL 3 or later. OK if I rename the glfw3dll.a to libglfw3dll.a it now builds! so yeah I was really looking forward to learning opengl until I discovered its a fucking nightmare :wacko: here's the example code I'm trying to build #include // include GLEW and new version of GL on Windows #include // GLFW helper library #include int main () { // start GL context and.
