glCompileShader

Name

glCompileShader â Compiles a shader object

C Specification

void glCompileShader( GLuint Â shader);

Parameters

shader: Specifies the shader object to be - compiled.

Description

glCompileShader compiles the source - code strings that have been stored in the shader object - specified by shader.

The compilation status will be stored as part of the - shader object's state. This value will be set to - GL_TRUE if the shader was compiled without - errors and is ready for use, and GL_FALSE - otherwise. It can be queried by calling - glGetShader - with arguments shader and - GL_COMPILE_STATUS.

Compilation of a shader can fail for a number of reasons - as specified by the OpenGL Shading Language Specification. - Whether or not the compilation was successful, information about - the compilation can be obtained from the shader object's - information log by calling - glGetShaderInfoLog.

Notes

glCompileShader - is available only if the GL version is 2.0 or greater.

Errors

GL_INVALID_VALUE is generated if - shader is not a value generated by - OpenGL.

GL_INVALID_OPERATION is generated if - shader is not a shader object.

GL_INVALID_OPERATION is generated if - glCompileShader is executed between the - execution of - glBegin - and the corresponding execution of - glEnd.

Associated Gets
