#467: Wrong detection on cairo

     Type:  defect     |      Status:  new                      
 Priority:  major      |   Milestone:  6.4.0                    
Component:  default    |     Version:  6.4.0 RCs                
 Keywords:             |    Platform:  Linux

 in configure.in:

 {{{
 ac_save_ldflags="$LDFLAGS"
 LDFLAGS="$LDFLAGS $CAIROLIB"
 AC_CHECK_FUNC(cairo_create,,[
 AC_MSG_ERROR([*** Unable to locate cairo_create() function.])
 ])
 LDFLAGS=${ac_save_ldflags}
 }}}


 but CAIROLIB is a library, not a linker flag. as Mandriva will use
 LDFLAGS="-Wl,--as-needed" by default, such a wrong link order will make it
 impossible to test the program:
 {{{
 gcc -o conftest -Wl,--as-needed -lcairo conftest.c
 }}

 It will produces: undefined reference to `cairo_create', because -lcairo
 is considered as objects, rather than libs.

 You should change ldflags to LIBS.
