Some strange code in configure.in

[Lionel Ulmer]

Hi all,

By looking at some guy's config.log, I found out this in configure.in :

   dnl Check for GLU32 library.
   AC_CHECK_LIB(GLU,glBegin,
                X_PRE_LIBS="$X_PRE_LIBS -lGLU"
                GLU32FILES='$(GLU32FILES)'
		GLU32_DLL=glu32
                ,,
	        $X_LIBS $X_PRE_LIBS -lXext -lX11 -lm $X_EXTRA_LIBS
   )

My question is why do we test for 'glBegin' in GLU and not something better
like, say, 'gluLookAt' ?

                          Lionel
