如何使用 Qt 编译 OpenGL ES2

发布于 2024-12-28 18:27:30 字数 3046 浏览 3 评论 0原文

我试图弄清楚如何让我的 Qt 程序编译并链接到 OpenGL ES2 函数。

我创建了一个简单的程序,它使用 QGLWidget 在我的 Qt 应用程序中使用旧的 OpenGL 1.0 管道绘制一些简单的三角形。我想使用 VBO 和着色器等高级 2.0 功能,因此我一开始就尝试为 VBO 分配一些缓冲区:

int ids[2];
glGenBuffers(2, ids);

不幸的是,我的项目找不到 glGenBuffers() 并且收到错误消息

GlWidget.cpp:103: error: 'glGenBuffers' was not declared in this scope

The start of qgl.h有“#elif Defined(QT_OPENGL_ES_2)”行,所以我尝试为预处理器设置它,但它仍然找不到glGenBuffers()。

我不知道接下来要尝试什么。请告诉我如何让我的 Qt 程序使用 OpenGL ES2。

这是我编译时得到的输出:

I'm trying to figure out how to get my Qt program to compile and link against OpenGL ES2 functions.

I've created a simple program that uses a QGLWidget to draw some simple triangles in my Qt application using the old OpenGL 1.0 pipeline. I'd like to use advanced 2.0 features like VBOs and shaders, so I started simply enough by trying to allocate some buffers for a VBO:

int ids[2];
glGenBuffers(2, ids);

Unfortunately, my project cannot find glGenBuffers() and I get the error message

GlWidget.cpp:103: error: 'glGenBuffers' was not declared in this scope

The start of qgl.h had the line "#elif defined(QT_OPENGL_ES_2)", so I tried setting that for the preprocessor, but it still couldn't find glGenBuffers().

I'm not sure what to try next. Please let me know how I can get my Qt program to use OpenGL ES2.

Here's the output I get when I compile:
