# 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 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.
