“#version 300 es” must appear in the first line of a shader program
written in GLSL ES version 3.00. If omitted,the shader will be
treated as targeting version 1.00.

所以我尝试在着色器的开头添加它,但这只会导致错误

Link Failed because of invalid vertex shader.

由.glGetProgramInfoLog报告.如果我使用“#version 300 gl”语句删除第一行,则着色器将编译并运行.

这是我的顶点着色器的代码

private final String vertexShaderCode =
        "#version 300 es \n" +
        "uniform mat4 uMVPMatrix; \n" +
        "attribute vec2 a_TexCoordinate; \n" +
        "attribute vec4 vPosition; \n" +
        "varying vec2 v_TexCoordinate; \n" +
        "void main() { \n" +
        "  v_TexCoordinate = a_TexCoordinate; \n" +
        "  gl_Position = uMVPMatrix * vPosition; \n" +
        "} \n";

我还将version语句添加到顶点和片段着色器,仍然得到相同的错误.

我在我的GLSurfaceView中调用了setEGLContextClientVersion(3),并添加了< uses-feature android：glEsVersion =“0x00030000”android：required =“true”/>到我的清单,表明该应用程序需要OpenGL ES 3.0.

我是否读错了OpenGL ES文档,我不需要添加此版本声明？如果我需要添加它,我做错了什么总是会导致错误？
