<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>
