    <p>I'm trying to run a <a href="http://www.cs.unm.edu/~angel/BOOK/INTERACTIVE_COMPUTER_GRAPHICS/FIFTH_EDITION/PROGRAMS/CHAPTER09/PHONG/phongV.c" rel="nofollow noreferrer">GLSL example</a>, but I can't.</p> <p>The error is in the line <code>glGetShaderiv(vShader, GL_COMPILE_STATUS, &amp;status);</code> where the program exits. <code>vShader</code> is the file <a href="http://www.cs.unm.edu/~angel/BOOK/INTERACTIVE_COMPUTER_GRAPHICS/FIFTH_EDITION/PROGRAMS/CHAPTER09/PHONG/vPhong.glsl" rel="nofollow noreferrer"><code>vPhong.glsl</code></a>.</p> <p>The error returned is:</p> <pre><code>0(18) : error C0000: syntax error, unexpected $undefined at token "&lt;undefined&gt;" 0(18) : error C0501: type name expected at token "&lt;undefined&gt;" </code></pre> <p>I have 'installed' and referenced GLEW and Glut and their lib-files. I have <code>glewInit</code>'ed my program.</p> <p>The program is able to find the .glsl-files.</p> <p>The weird thing is that I am able to run a <a href="http://www.cs.unm.edu/~angel/BOOK/INTERACTIVE_COMPUTER_GRAPHICS/FIFTH_EDITION/PROGRAMS/WINDOWS_BINARIES/GLSL/GLSL%20Example/Debug/GLSL%20Example.exe" rel="nofollow noreferrer">precompiled GLSL-demo</a>, and also compile and run <a href="http://www.cs.unm.edu/~angel/BOOK/INTERACTIVE_COMPUTER_GRAPHICS/FIFTH_EDITION/PROGRAMS/WINDOWS_BINARIES/GLSL/" rel="nofollow noreferrer">the project</a> on my pc. The "initializations" in the non-working program and this are the same.</p> <p>I have tried copying the defective source into the successful project, to see if there was something in the project settings causing the error, but unfortunately, that wasn't the case. <strong>So the error seems to be in the C++ code, not the project.</strong></p> <hr> <p><strong>PROGRESS:</strong></p> <p>On my Windows 7-machine i got "Access violation" when running through Visual Studio. The program just stopped working if I ran it "alone". On a Windows XP-machine I got an uncaught exception.</p> <p>I received no errors or warnings (apart from a warning that <code>fopen</code> is unsafe) when I compiled the program.</p> <p>Visual Studio highlighted the line <code>vShader = glCreateShader(GL_VERTEX_SHADER);</code> as the source of the error.</p> <p>Adding <code>glewInit();</code> fixed the above errors.</p>

    2. COa little more information at which point the program stops working (I would assume running it through visual studio will also show you the origin of the exception) would also be helpful (provided the link is fixed of course...)

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.
