纹理映射和照明顶点着色器错误Java OpenGL,java,opengl,opengl-es,fragment-shader,vertex-shader,Java,Opengl,Opengl Es,Fragment Shader,Vertex Shader,我正在尝试将纹理映射到3D立方体，并尝试编写着色器，使其具有照明和纹理 我试着只写纹理着色器，它可以工作。 我还尝试了仅将3D值设置为红色的灯光着色器，该灯光着色器也可以工作。但当我试图将两者结合起来时，我遇到了问题。 我在下面提供了我的代码，但是我得到了一个错误 未编译附加的顶点着色器。无法链接着色器。 顶点着色器 #version 330 core layout(location = 0) in vec4 vPosition; layout(location = 1) in vec3 vN

v~StubRoutines:：调用_stub
正如我之前所说，在使用is之前，我们必须检查着色器编译链接状态

我就是这样做的（OpenGL ES 2.0）：

您还可以以更具信息性的方式显示消息框调用，如：

QMessageBox::warning(this, QString("Vertex shader compilation error."),
                                     QString(infoLog), QMessageBox::Yes | QMessageBox::Cancel, QMessageBox::Yes);

QMessageBox::warning(this, QString("Fragment shader compilation error."),
                                     QString(infoLog), QMessageBox::Yes | QMessageBox::Cancel, QMessageBox::Yes);

QMessageBox::warning(this, QString("Shader linkage error."),
                                     QString(infoLog), QMessageBox::Yes | QMessageBox::Cancel, QMessageBox::Yes);
这样我们就可以大大缩小bug搜索的范围

我突然发现了一些关于这个bug的信息，看起来像这样。我想这只是Windows的问题。试着在Linux操作系统上构建你的应用程序

首先，必须在链接之前为指定rendertarget输出

glBindFragDataLocation(program, 0, "fColor");
你能发布hs_err_pid4376.log文件的内容吗？这是一个很长的文件，我什么都不懂。@Mykolais它真的是
glGetShaderInfoLog
的输出吗？我想调用该函数是一个错误，请确保保存消息的变量的内存没有问题……我已经尝试编译了你的着色器，但是在顶点着色器：
vTexCoord
在声明中以不同的大小写开始。
