glCompileShader - OpenGL ES 3.1 Reference Pages

## 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 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 glGetShaderiv with arguments `shader` and `GL_COMPILE_STATUS`.

Compilation of a shader can fail for a number of reasons as specified by the OpenGL ES 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.

## 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.

## Associated Gets

glGetShaderInfoLog with argument `shader`

glGetShaderiv with arguments `shader` and `GL_COMPILE_STATUS`
