my shader that work with renderMonkey don't work with my opengl program please help !

EDIT : my info log say this :
Link successful. The GLSL vertex shader will run in hardware. The GLSL fragment shader will run in hardware.
and i have tried with another shader(toon shading) and it works, the problem is for the other shader (per pixel lighting): i have no lighting... even not gouraud.
so i suppose (can it be something else ?) that some variable which are in my shader are not in the opengl program.
i use in my shader "gl_LightSource[0].halfVector". HalfVector is not present in my opengl program, is it generated by opengl or have i to do something ?if yes what ? in the shader or in the opengl program ?
i put the code of the lighting part of my opengl program and the shader code (per pixel lighting):
see the end of the page for a copy of that message + the code

original first message :
Hi,
I have made a shader which works with renderMonkey, but when i add this shader to my opengl program the model appears in black.
I have used glIntercept and i have these errors :
GL ERROR - Function glAttachShader generated error GL_INVALID_VALUE
GL ERROR - Function glAttachShader generated error GL_INVALID_VALUE
GL ERROR - Function glLinkProgram generated error GL_INVALID_VALUE
GL ERROR - Function glUseProgram generated error GL_INVALID_VALUE
this is my code :

EDIT : i have changed the "unsigned int" by "GLuint" and now i have these errors :
GLDriver - Shutdown - Current OpenGL context 0x10000?
GLDriver - Shutdown - Outstanding OpenGL context 0x10000 ?

GLint status=0 ;
glGetObjectParameterivARB(fsh, GL_OBJECT_LINK_STATUS_ARB, &status);
cout<<"status "<<dec<<status<<endl ;
this gives me the status equal to 0, so there is a link problem, but can i do ?
glGetObjectParameterivARB(fsh, GL_OBJECT_LINK_STATUS_ARB, &status);

yes but with that code my file which contain the log is empty :
i have also noticed that infologLength has a lenght of 1...
[Edited by - TheSeb on June 3, 2005 5:13:35 PM]
int infologLength = 0; int charsWritten = 0; char *infoLog; glGetObjectParameterivARB(vsh, GL_OBJECT_INFO_LOG_LENGTH_ARB, &infologLength); if (infologLength > 0) { cout<<"shader "<<infologLength<<endl ; infoLog = (char *)malloc(infologLength); glGetInfoLogARB(vsh, infologLength, &charsWritten, infoLog); ofstream oFile3("infoLogFile.txt"); oFile3<<infoLog ; free(infoLog); }i have also noticed that infologLength has a lenght of 1...

i have used gl intercept and it gives me that :
GL ERROR - Function glUseProgram(2147483649) generated error GL_INVALID_OPERATION
GL ERROR - Function glGetObjectParameterivARB(536870913,GL_LINK_STATUS,0x12fda4) generated error GL_INVALID_ENUM
GLDriver - Shutdown - Current OpenGL context 0x10000?
GLDriver - Shutdown - Outstanding OpenGL context 0x10000 ?
===================================================
Log End.
i don't understand what's wrong with my code... (i reput it here)

ok thanks, my info log say this :

so i suppose (can it be something else ?) that some variable which are in my shader are not in the opengl program.
i use in my shader "gl_LightSource[0].halfVector". HalfVector is not present in my opengl program, is it generated by opengl or have i to do something ?if yes what ? in the shader or in the opengl program ?
i put the code of the lighting part of my opengl program and the shader code (per pixel lighting):
