Question

我正在尝试从opengl教程编译以下程序，但是要解决这些奇怪的错误。我无法弄清楚如何修复这些，帮助。 IDE代码块12.11，Windows 7 32位，gcc 4.7.1

这是代码

#include <GLTools.h>
#include <GL/glut.h>
#include <GLShaderManager.h>
GLBatch triangleBatch;
GLShaderManager shaderManager;
void ChangeSize(int w, int h)
{
    glViewport(0, 0, w, h);
}

void SetupRC()
{
    glClearColor(0.0f, 0.0f, 1.0f, 1.0f );
    shaderManager.InitializeStockShaders();
    GLfloat vVerts[] = { -0.5f, 0.0f, 0.0f,
                          0.5f, 0.0f, 0.0f,
                          0.0f, 0.5f, 0.0f };
    triangleBatch.Begin(GL_TRIANGLES, 3);
    triangleBatch.CopyVertexData3f(vVerts);
    triangleBatch.End();
}
void RenderScene(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);
    GLfloat vRed[] = { 1.0f, 0.0f, 0.0f, 1.0f };
    shaderManager.UseStockShader(GLT_SHADER_IDENTITY, vRed);
    triangleBatch.Draw();
    glutSwapBuffers();
}
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("Triangle");
    glutReshapeFunc(ChangeSize);
    glutDisplayFunc(RenderScene);
    GLenum err = glewInit();
    if (GLEW_OK != err) {
        fprintf(stderr, "GLEW Error: %s\n", glewGetErrorString(err));
        return 1;
    }
SetupRC();
glutMainLoop();
return 0;
}

错误 -

undefined reference to GLBatch::Begin(unsigned int, unsigned int, unsigned int)
undefined reference to GLBatch::End()
undefined reference to GLShaderManager::UseStockShader(GLT_STOCK_SHADER, ...)

GLBatch上的快速谷歌给了我一个提示，你可能需要添加链接这个库以及gltools.lib，试试看，让我知道。

未定义的GLShaderManager和GLBatch参考
