上未实现的Nexus的OpenGL ES 3.0着色器功能5 / 4.4奇巧 [英] Opengl ES 3.0 shader functions unimplemented on Nexus 5/KitKat 4.4

问题描述

我在使用任何的OpenGL 3.0着色器功能上我的Nexus 5W /奇巧4.4，我得到叫未实现的OpenGL ES API的功能，没有运气，如

I'm having no luck using any of the OpenGL 3.0 shader functions on my Nexus 5 w/ KitKat 4.4, I get "called unimplemented opengl es api" for functions such as

glCreateProgram()
glShaderSource()
glCompileShader()

e.t.c。我执行所有的呼叫，而OpenGL上下文激活。我无法想象，这些功能将无法实施，所以相信我一定做错了什么！我已经包括以下

e.t.c. I am performing all calls whilst the OpenGL context is active. I can't imagine that these functions would not be implemented, so believe I must be doing something wrong! I have included the following

<GLES3/gl3.h>
<GLES2/gl2ext.h>
<GLES3/gl3platform.h>

和现在用

-lGLESv3

在我的LOCAL_LDLIBS。我注意到，在EGL / egl.h没有EGL_OPENGL_ES3_BIT，所以上下文创建过程中，如果我不定义EGL_RENDERABLE_TYPE，或者如果我使用EGL_OPENGL_ES2_BIT，结果都是一样的。

in my LOCAL_LDLIBS. I noticed that in EGL/egl.h there is no EGL_OPENGL_ES3_BIT, so during context creation if I don't define EGL_RENDERABLE_TYPE, or if I use EGL_OPENGL_ES2_BIT, the results are the same.

这是我在哪里的情况下，它可以帮助多一点信息：我移植的OpenGL我的游戏引擎从Windows使用OpenGL ES 3.0和NDK为Android。我把一切都ok了编译没有错误，并且已经测试和验证窗口，GL上下文管理，生命周期Android的整合和发动机的基本运行工作正常。我有一个简单的激活的背景下基本的场景，进行glClearColour然后交换缓冲区，从黑到脉动红每一秒，并且它在Windows上它的工作原理是一样的。

A bit more info on where I am in case it helps: I'm porting my OpenGL game engine from Windows to Android using OpenGL ES 3.0 and the NDK. I have everything compiling ok with no errors, and have tested and verified that windowing, GL context management, Android lifecycle integration and the basic running of the engine works ok. I have a basic scene which simply activates the context, performs a glClearColour then swaps buffers, pulsating from black to red every second, and it works the same as it does on Windows.

任何帮助将是AP preciated！

Any help would be appreciated!

推荐答案

原来我也不得不使用EGL_CONTEXT_CLIENT_VERSION使用eglCreateContext时：

Turns out I also had to use EGL_CONTEXT_CLIENT_VERSION when using eglCreateContext:

const EGLint attribs2[] = {EGL_CONTEXT_CLIENT_VERSION, 3, EGL_NONE};
context = eglCreateContext(displayHandle, config, NULL, attribs2);
