1 dnl Like AC_CHECK_FUNCS, but allows the function definition to be 2 dnl a macro. This allows for detection of functions which are renamed 3 dnl with macros to something other than the name we are testing with. 4 AC_DEFUN([AX_CHECK_FUNCS_COMP],[ 5 dnl This is magic to make autoheader pick up the config.h.in templates 6 dnl automatically. This uses macros which are probably not public 7 dnl (not documented anyway) but this works at least with Automake 2.59. 8 AC_FOREACH([AX_Func], [$1], 9 [AH_TEMPLATE(AS_TR_CPP(HAVE_[]AX_Func), 10 [Define to 1 if you have the `]AX_Func[' function or macro.])])dnl 11 for ax_func in $1; do 12 ax_fname=`echo $ax_func | sed "s/@<:@^a-zA-Z0-9_@:>@/_/g"` 13 ax_symbolname=`echo $ax_func | sed "s/@<:@^a-zA-Z0-9_@:>@/_/g" | tr "@<:@a-z@:>@" "@<:@A-Z@:>@"` 14 AC_CACHE_CHECK([for $ax_func], ax_cv_func_${ax_fname}, [ 15 AC_LINK_IFELSE( 16 [ AC_LANG_PROGRAM( 17 [$4 18 void *foo = $ax_func; 19 ], 20 [ return foo != $ax_func; ])], 21 [ eval "ax_cv_func_${ax_fname}=\"yes\"" ], 22 [ eval "ax_cv_func_${ax_fname}=\"no\"" ])]) 23 if eval "test \"\${ax_cv_func_${ax_fname}}\" = \"yes\""; then 24 AC_DEFINE_UNQUOTED(HAVE_${ax_symbolname}, 1, 25 [Define to 1 if you have the $ax_func() function.]) 26 $2 27 else 28 true 29 $3 30 fi 31 done 32 ])dnl 33
