al_build_shader(3)	   Library Functions Manual	    al_build_shader(3)

NAME
       al_build_shader - Allegro 5 API

SYNOPSIS
	      #include <allegro5/allegro.h>

	      bool al_build_shader(ALLEGRO_SHADER *shader)

DESCRIPTION
       This  is	 required before the shader can	be used	with al_use_shader(3).
       It should be called after successfully attaching	the pixel and/or  ver-
       tex     shaders	   with	    al_attach_shader_source(3)	  or	al_at-
       tach_shader_source_file(3).

       Returns true on success and false on error, in which case the error log
       is updated.  The	error log can be retrieved with	al_get_shader_log(3).

	      Note: If you are using the  ALLEGRO_PROGRAMMABLE_PIPELINE	 flag,
	      then  you	 must specify both a pixel and a vertex	shader sources
	      for anything to be rendered.

SINCE
       5.1.6
