glCompileShader

Name

glCompileShader Compiles a shader object

C Specification

void glCompileShader(GLuint 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 is stored as part of the shader object's state. This value is 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 of type GL_SHADER_OBJECT.

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