我的顶点着色器中有三个glsl属性

attribute highp   vec4  Position;
attribute mediump vec4  UV;
attribute mediump vec3  Normal;

即时通讯绑定使用

glBindAttribLocation(program, 0, "Position");
glBindAttribLocation(program, 1, "Normal");
glBindAttribLocation(program, 2, "UV");

但是,我收到了一个错误

无法找到顶点着色器属性"Normal"以匹配BindAttributeLocation请求.

为什么它可以找到Position和UV属性,但不能找到Normal属性.

任何帮助都会受到高度赞赏,因为我很困惑.

干杯

编辑:我在Android OpenGLES20上遇到了同样的问题.我将添加示例代码:该类的其余部分是官方的GLSurfaceView教程

public void onSurfaceCreated(GL10 glUnused, EGLConfig config) {

    String mVertexShader =  "uniform mat4 uMVPMatrix;\n " +
            "attribute vec4 aPosition;\n " +
            "attribute vec4 aNormal; \n " + //this is the line I added
            "attribute vec2 aTextureCoord;\n " +
            "varying vec2 vTextureCoord;\n " +
            "void main() {\n " +
            "gl_Position = uMVPMatrix …
