问题
I follow the book "OpenGL SuperBible 5th Edition" to study openGL, the capture 6th demo to create shader by hand all not work. Like the demo of "ShadedTriangle", to create a triangle but only create a black ground window.
The error is "The shader at ShadedIdentity.vp failed to compile with the following error: ERROR: 0:5: '' : version '150' is not supported"
and I change the GLSL version to 330,440, 150 etc, but all not work.
and now my mac version is 10.12.5 (16F73) , and the version of code glGetString(GL_VERSION)
is 2.1 INTEL-10.25.13
the follow is the full code:
#include <GLTools.h> // OpenGL toolkit
#include <GLShaderManager.h> // Shader Manager Class
#ifdef __APPLE__
#include <glut/glut.h> // OS X version of GLUT
#else
#define FREEGLUT_STATIC
#include <GL/glut.h> // Windows FreeGlut equivalent
#endif
GLBatch triangleBatch;
GLShaderManager shaderManager;
GLint myIdentityShader;
///////////////////////////////////////////////////////////////////////////////
// Window has changed size, or has just been created. In either case, we need
// to use the window dimensions to set the viewport and the projection matrix.
void ChangeSize(int w, int h)
{
glViewport(0, 0, w, h);
}
///////////////////////////////////////////////////////////////////////////////
// This function does any needed initialization on the rendering context.
// This is the first opportunity to do any OpenGL related tasks.
void SetupRC()
{
// Blue background
glClearColor(0.0f, 0.0f, 0.0f, 1.0f );
shaderManager.InitializeStockShaders();
// Load up a triangle
GLfloat vVerts[] = { -0.5f, 0.0f, 0.0f,
0.5f, 0.0f, 0.0f,
0.0f, 0.5f, 0.0f };
GLfloat vColors [] = { 1.0f, 0.0f, 0.0f, 1.0f,
0.0f, 1.0f, 0.0f, 1.0f,
0.0f, 0.0f, 1.0f, 1.0f };
triangleBatch.Begin(GL_TRIANGLES, 3);
triangleBatch.CopyVertexData3f(vVerts);
triangleBatch.CopyColorData4f(vColors);
triangleBatch.End();
myIdentityShader = gltLoadShaderPairWithAttributes("ShadedIdentity.vp", "ShadedIdentity.fp", 2,
GLT_ATTRIBUTE_VERTEX, "vVertex", GLT_ATTRIBUTE_COLOR, "vColor");
}
///////////////////////////////////////////////////////////////////////////////
// Cleanup
void ShutdownRC()
{
glDeleteProgram(myIdentityShader);
}
///////////////////////////////////////////////////////////////////////////////
// Called to draw scene
void RenderScene(void)
{
// Clear the window with current clearing color
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);
glUseProgram(myIdentityShader);
triangleBatch.Draw();
// Perform the buffer swap to display back buffer
glutSwapBuffers();
}
///////////////////////////////////////////////////////////////////////////////
// Main entry point for GLUT based programs
int main(int argc, char* argv[])
{
gltSetWorkingDirectory(argv[0]);
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH | GLUT_STENCIL);
glutInitWindowSize(800, 600);
glutCreateWindow("Shaded Triangle");
glutReshapeFunc(ChangeSize);
glutDisplayFunc(RenderScene);
GLenum err = glewInit();
if (GLEW_OK != err) {
fprintf(stderr, "GLEW Error: %s\n", glewGetErrorString(err));
return 1;
}
SetupRC();
const char* version = (const char*)glGetString(GL_VERSION);
fprintf(stderr, "OpenGLVersion: %s\n", version);
glutMainLoop();
ShutdownRC();
return 0;
}
and the ShadedIdentity.vp is :
// The ShadedIdentity Shader
// Vertex Shader
// Richard S. Wright Jr.
// OpenGL SuperBible
#version 150
in vec4 vColor;
in vec4 vVertex;
out vec4 vVaryingColor;
void main(void)
{
vVaryingColor = vColor;
gl_Position = vVertex;
}
so ,how to solve this problem
Thanks.

1.50 requires OpenGL 3.2 support. Unless you can get a newer driver (or a GPU), I think you're out of luck on this one.
