Question

我有一个奇怪的，令人沮丧的问题。我有一个在Windows和Linux上运行良好的着色器。当我把它移到我的Mac上时，它给了我可怕的错误和黑屏。

// C++

QGLShader *vshader1 = new QGLShader(QGLShader::Vertex, this);


    vshader1->compileSourceFile(":shaders/vert1.vert");

    QGLShader *fshader1 = new QGLShader(QGLShader::Fragment, this);

    fshader1->compileSourceFile(":shaders/frag1.frag");

    program1.addShader(vshader1);
    program1.addShader(fshader1);
    program1.link();

所以基本上如果我放入版本#version 150或#version 410，它会抱怨没有指定#version。如果我指定#version 130或#version 350，它会抱怨我已经要求提供无效版本（不应该只是恢复到可用版本吗？）

知道发生了什么事吗？这特别令人恼火，因为我指定了#version并且我没有使用变量关键字。

Answer 1

我相信#version 150 core应该出现在着色器文件的最顶部，其后有一个空行，并引用core，legacy或es。 ..

GLSL给出了一个奇怪的错误：＆＃34; #version需要和丢失＆＃34;只在mac上
