   intel cards: "no errors" from glsl
  hello, i am using this code to check if my glsl shader compiled fine.    glGetObjectParameterivARB(obj, GL_OBJECT_INFO_LOG_LENGTH_ARB, &infologLength);    if (infologLength > 1)    {int charsWritten  = 0;char * const infoLog = new char[infologLength];glGetInfoLogARB(obj, infologLength, &charsWritten, infoLog);tError(infoLog, false);delete infoLog;    }}the length of the returned string is empty on nvidia and ATI cards, but on intel cards this one returns the string "no errors." now what is the best way to find out, if there are really no errors? should i just check for this string? or is there a convention what this function glGetInfoLogARB should return?   
  Use glGetShader with GL_COMPILE_STATUS as the parameter. Check the man page for glGetProgram if you want to check for errors in the program linking also.   ;  That's not the way to see if the shader compilation was successful, the correct way is:glGetObjectParameterivARB(obj, GL_OBJECT_COMPILE_STATUS_ARB, &status);;  thanks! is there an opengl function for this for versions < 2.0 ? some ARB extension  maybe?   ;Quote:Original post by ehmdjiithanks! is there an opengl function for this for versions < 2.0 ? some ARB extension  maybe?ButglGetObjectParameterivARB(obj, GL_OBJECT_COMPILE_STATUS_ARB, &status);is an extension from that GL_ARB_shading_language_100.
