undefined reference to 'glGetQueryObjectui64vEXT'

[aRcleR]

Hi, I'm trying to use some profiling tools for opengles 2.0 based on GL_GLEXT_PROTOTYPES.
By now I get the error "undefined reference to 'glGetQueryObjectui64vEXT'"
I've setted the variable in a lots of places, but I always get this error.

If the variable is not setted, the the function is not available because the GL_GTEXT_PROTOTYPES is not defined:

#ifdef GL_GLEXT_PROTOTYPES **// IS NOT DEFINED!!**
GL_APICALL void GL_APIENTRY glGenQueriesEXT (GLsizei n, GLuint *ids);
GL_APICALL void GL_APIENTRY glDeleteQueriesEXT (GLsizei n, const GLuint *ids);
GL_APICALL GLboolean GL_APIENTRY glIsQueryEXT (GLuint id);
GL_APICALL void GL_APIENTRY glBeginQueryEXT (GLenum target, GLuint id);
GL_APICALL void GL_APIENTRY glEndQueryEXT (GLenum target);
GL_APICALL void GL_APIENTRY glQueryCounterEXT (GLuint id, GLenum target);
GL_APICALL void GL_APIENTRY glGetQueryivEXT (GLenum target, GLenum pname, GLint *params);
GL_APICALL void GL_APIENTRY glGetQueryObjectivEXT (GLuint id, GLenum pname, GLint *params);
GL_APICALL void GL_APIENTRY glGetQueryObjectuivEXT (GLuint id, GLenum pname, GLuint *params);
GL_APICALL void GL_APIENTRY glGetQueryObjecti64vEXT (GLuint id, GLenum pname, GLint64 *params);
GL_APICALL void GL_APIENTRY glGetQueryObjectui64vEXT (GLuint id, GLenum pname, GLuint64 *params);
#endif

Could someone helpme with this issue? Any ideas?
Thanks
