You can override -dnl the shellvar-default of CFLAGS of course. The order of arguments -dnl stems from the explicit macros like AX_CFLAGS_WARN_ALL. -dnl -dnl The macro is a lot simpler than any special AX_CFLAGS_* macro (or -dnl ac_cxx_rtti.m4 macro) but allows to check for arbitrary options. -dnl However, if you use this macro in a few places, it would be great -dnl if you would make up a new function-macro and submit it to the -dnl ac-archive. -dnl -dnl - $1 option-to-check-for : required ("-option" as non-value) -dnl - $2 shell-variable-to-add-to : CFLAGS -dnl - $3 action-if-found : add value to shellvariable -dnl - $4 action-if-not-found : nothing -dnl -dnl note: in earlier versions, $1-$2 were swapped. We try to detect the -dnl situation and accept a $2=~/-/ as being the old option-to-check-for. -dnl -dnl also: there are other variants that emerged from the original macro -dnl variant which did just test an option to be possibly added. However, -dnl some compilers accept an option silently, or possibly for just -dnl another option that was not intended. Therefore, we have to do a -dnl generic test for a compiler family. For gcc we check "-pedantic" -dnl being accepted which is also understood by compilers who just want -dnl to be compatible with gcc even when not being made from gcc sources. -dnl -dnl see also: -dnl AX_CFLAGS_SUN_OPTION AX_CFLAGS_HPUX_OPTION -dnl AX_CFLAGS_AIX_OPTION AX_CFLAGS_IRIX_OPTION -dnl -dnl @, tested, experimental -dnl @version $Id: ax_cflags_gcc_option.m4,v 1.5 2003/11/29 08:13:25 guidod Exp $ -dnl @author Guido Draheim <guidod@gmx.de> -dnl http://ac-archive.sourceforge.net/C_Support/ax_cflags_gcc_option.m4 -dnl -AC_DEFUN([AX_CFLAGS_GCC_OPTION_OLD], [dnl -AS_VAR_PUSHDEF([FLAGS],[CFLAGS])dnl -AS_VAR_PUSHDEF([VAR],[ac_cv_cflags_gcc_option_$2])dnl -AC_CACHE_CHECK([m4_ifval($1,$1,FLAGS) for gcc m4_ifval($2,$2,-option)], -VAR,[VAR="no, unknown" - AC_LANG_SAVE - AC_LANG_C - ac_save_[]FLAGS="$[]FLAGS" -for ac_arg dnl -in "-pedantic % m4_ifval($2,$2,-option)" dnl GCC - # -do FLAGS="$ac_save_[]FLAGS "`echo $ac_arg | sed -e 's,%%.*,,' -e 's,%,,'` - AC_TRY_COMPILE([],[return 0;], - [VAR=`echo $ac_arg | sed -e 's,.*% *,,'` ; break]) -done - FLAGS="$ac_save_[]FLAGS" - AC_LANG_RESTORE -]) -case ".$VAR" in - .ok|.ok,*) m4_ifvaln($3,$3) ;; - .|.no|.no,*) m4_ifvaln($4,$4) ;; - *) m4_ifvaln($3,$3,[ - if echo " $[]m4_ifval($1,$1,FLAGS) " | grep " $VAR " 2>&1 >/dev/null - then AC_RUN_LOG([: m4_ifval($1,$1,FLAGS) does contain $VAR]) - else AC_RUN_LOG([: m4_ifval($1,$1,FLAGS)="$m4_ifval($1,$1,FLAGS) $VAR"]) - m4_ifval($1,$1,FLAGS)="$m4_ifval($1,$1,FLAGS) $VAR" - fi ]) ;; -esac -AS_VAR_POPDEF([VAR])dnl -AS_VAR_POPDEF([FLAGS])dnl -]) - - -dnl ------------------------------------------------------------------------- - -AC_DEFUN([AX_CFLAGS_GCC_OPTION_NEW], [dnl -AS_VAR_PUSHDEF([FLAGS],[CFLAGS])dnl -AS_VAR_PUSHDEF([VAR],[ac_cv_cflags_gcc_option_$1])dnl -AC_CACHE_CHECK([m4_ifval($2,$2,FLAGS) for gcc m4_ifval($1,$1,-option)], -VAR,[VAR="no, unknown" - AC_LANG_SAVE - AC_LANG_C - ac_save_[]FLAGS="$[]FLAGS" -for ac_arg dnl -in "-pedantic % m4_ifval($1,$1,-option)" dnl GCC - # -do FLAGS="$ac_save_[]FLAGS "`echo $ac_arg | sed -e 's,%%.*,,' -e 's,%,,'` - AC_TRY_COMPILE([],[return 0;], - [VAR=`echo $ac_arg | sed -e 's,.*% *,,'` ; break]) -done - FLAGS="$ac_save_[]FLAGS" - AC_LANG_RESTORE -]) -case ".$VAR" in - .ok|.ok,*) m4_ifvaln($3,$3) ;; - .|.no|.no,*) m4_ifvaln($4,$4) ;; - *) m4_ifvaln($3,$3,[ - if echo " $[]m4_ifval($2,$2,FLAGS) " | grep " $VAR " 2>&1 >/dev/null - then AC_RUN_LOG([: m4_ifval($2,$2,FLAGS) does contain $VAR]) - else AC_RUN_LOG([: m4_ifval($2,$2,FLAGS)="$m4_ifval($2,$2,FLAGS) $VAR"]) - m4_ifval($2,$2,FLAGS)="$m4_ifval($2,$2,FLAGS) $VAR" - fi ]) ;; -esac -AS_VAR_POPDEF([VAR])dnl -AS_VAR_POPDEF([FLAGS])dnl -]) - - -AC_DEFUN([AX_CFLAGS_GCC_OPTION],[ifelse(m4_bregexp([$2],[-]),-1, -[AX_CFLAGS_GCC_OPTION_NEW($@)],[AX_CFLAGS_GCC_OPTION_OLD($@)])]) |
