    <p>So, I was reading <a href="http://ogldev.atspace.co.uk/www/tutorial02/tutorial02.html" rel="nofollow">http://ogldev.atspace.co.uk/www/tutorial02/tutorial02.html</a> and it said I needed math_3d.h for Vector3f.</p> <p>I tried to include it:</p> <pre><code>#include &lt;stdio.h&gt; #include "GL/glew.h" #include "GL/gl.h" #include "GL/freeglut.h" #include "math_3d.h" void render() { glClearColor(0.0, 0.0, 0.0, 0.0); glClear(GL_COLOR_BUFFER_BIT); glutSwapBuffers(); glFlush(); } int main(int argc, char** argv) { glutInit(&amp;argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA); glutInitWindowSize(800, 600); glutInitWindowPosition(100, 100); glutCreateWindow("OpenGL - First window demo"); /* Set */ GLenum res = glewInit(); if (res != GLEW_OK) { fprintf(stderr, "Error: '%s'\n", glewGetErrorString(res)); return 1; } Vector3f vertices[1]; glutDisplayFunc(render); glutMainLoop(); return 0; } </code></pre> <p>G++ said "main.cpp:7:21: fatal error: math_3d.h: No such file or directory". I looked for an Arch Linux package for it, but I found nothing.</p> <p>I found the file here:</p> <p><a href="http://ogldev.googlecode.com/svn-history/r75/trunk/tutorial36/math_3d.h" rel="nofollow">http://ogldev.googlecode.com/svn-history/r75/trunk/tutorial36/math_3d.h</a></p> <p>Am I supposed to download that file and place it my project directory, or is there a cleaner way of doing it?</p> <p>Also, if I do include it in my directory, how can I add it to the g++ line?</p> <pre><code>gcc main.cpp -o main -lGLEW -lglut -lGL </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
