ARB extension with GLEW

[acuvue]

Hello

I am trying to use GLSL(ARB extention) with GLEW.
My development environment and code are bellow.

• [li]Windows XP Home []Visual Studio 2005 professional[]Mobirity Radeon 9700[]GLEW version 1.5.1[]OpenGL version 1.5.4456 WinXP Release (from glGetString(GL_VERSION))

m_fragment_shader = glCreateShaderObjectARB(GL_FRAGMENT_SHADER_ARB);

char* vs = file2string(vertexFileName);
char* ps = file2string(fragmentFileName);
const char* vertex_shader_source = vs;
const char* fragment_shader_source = ps;

// Load Shader Sources
glShaderSourceARB(m_vertex_shader, 1, &vertex_shader_source, NULL);
glShaderSourceARB(m_fragment_shader, 1, &fragment_shader_source, NULL);

if ( glGetError() != GL_NO_ERROR ) {
return false;
}

// Compile The Shaders
glCompileShaderARB(m_vertex_shader); <----crash here
glCompileShaderARB(m_fragment_shader);

if ( glGetError() != GL_NO_ERROR ) {
return false;
}

// print log
printLog(m_vertex_shader);
printLog(m_fragment_shader);

free(vs);
free(ps);

// Attach The Shader Objects To The Program Object
glAttachObjectARB(m_program, m_vertex_shader);
glAttachObjectARB(m_program, m_fragment_shader);

// Link The Program Object
glLinkProgramARB(m_program);
return true;

My program can work in another computer which has Geforce7900.

My computer can compile another shader program.
(For example http://ati.amd.com/developer/sdk/RadeonSDK/Html/Samples/OpenGL/GLSLSimpleShader.html )

Help me!

Sorry. I found problem.
Vertex shader program was too heavy for Mobility Radeon 9700.

1. Where’s the question?

2. Since you use a laptop, you most certainly do not have the latest driver installed. Try DhMod-Tool to configure ATI drivers to be able to install them on laptops, too (for more information abuot this, consult the almighty google).

Thanks for your advice
I will try it.

Oh, i didn’t see the red arrow. Anyway, glad you found your problem.

Old Radeon drivers had a bad habit of going babanas instead of reporting an error with shader compilation.
It may be a good idea to make an application catch exceptions and inform user about a problem with driver (of course if it’s not the application that caused exception by passing bad data to driver or calling non-existing entry point).

I didn’t realize that my problem was in the driver.
Thank you very much
