	<para><function>glCompileShader</function> compiles the source
	code strings that have been stored in the shader object
	specified by <parameter>shader</parameter>.</para>

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

	<para>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
	<citerefentry><refentrytitle>glGetShaderInfoLog</refentrytitle></citerefentry>.</para>
