dnl @synopsis AX_CFLAGS_IRIX_OPTION (optionflag [,[shellvar][,[A][,[NA]]]) dnl dnl AX_CFLAGS_IRIX_OPTION(-go_for_it) would show a message as like dnl "checking CFLAGS for irix/cc -go_for_it ... yes" and adds the dnl optionflag to CFLAGS if it is understood. You can override the dnl shellvar-default of CFLAGS of course. The order of arguments stems dnl from the explicit macros like AX_CFLAGS_WARN_ALL. dnl dnl The cousin AX_CXXFLAGS_IRIX_OPTION would check for an option to add dnl to CXXFLAGS - and it uses the autoconf setup for C++ instead of C dnl (since it is possible to use different compilers for C and C++). 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 (or CXXFLAGS in the other case) 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 dnl option-to-check-for. dnl dnl see also: AX_CFLAGS_GCC_OPTION for the widely used original dnl variant. dnl dnl @category C dnl @author Guido Draheim <guidod@gmx.de> dnl @version 2005-01-21 dnl @license GPLWithACException AC_DEFUN([AX_CFLAGS_IRIX_OPTION_OLD], [dnl AS_VAR_PUSHDEF([FLAGS],[CFLAGS])dnl AS_VAR_PUSHDEF([VAR],[ac_cv_cflags_irix_option_$2])dnl AC_CACHE_CHECK([m4_ifval($1,$1,FLAGS) for irix/cc m4_ifval($2,$2,-option)], VAR,[VAR="no, unknown" AC_LANG_SAVE AC_LANG_C ac_save_[]FLAGS="$[]FLAGS" for ac_arg dnl in "-fullwarn -use_readonly_const % m4_ifval($2,$2,-option)" dnl IRIX C # do FLAGS="$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 the only difference - the LANG selection... and the default FLAGS AC_DEFUN([AX_CXXFLAGS_IRIX_OPTION_OLD], [dnl AS_VAR_PUSHDEF([FLAGS],[CXXFLAGS])dnl AS_VAR_PUSHDEF([VAR],[ac_cv_cxxflags_irix_option_$2])dnl AC_CACHE_CHECK([m4_ifval($1,$1,FLAGS) for irix/cc m4_ifval($2,$2,-option)], VAR,[VAR="no, unknown" AC_LANG_SAVE AC_LANG_CXX ac_save_[]FLAGS="$[]FLAGS" for ac_arg dnl in "-fullwarn -use_readonly_const % m4_ifval($2,$2,-option)" dnl IRIX C # do FLAGS="$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_IRIX_OPTION_NEW], [dnl AS_VAR_PUSHDEF([FLAGS],[CFLAGS])dnl AS_VAR_PUSHDEF([VAR],[ac_cv_cflags_irix_option_$1])dnl AC_CACHE_CHECK([m4_ifval($2,$2,FLAGS) for irix/cc m4_ifval($1,$1,-option)], VAR,[VAR="no, unknown" AC_LANG_SAVE AC_LANG_C ac_save_[]FLAGS="$[]FLAGS" for ac_arg dnl in "-fullwarn -use_readonly_const % m4_ifval($1,$1,-option)" dnl IRIX C # do FLAGS="$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 ]) dnl the only difference - the LANG selection... and the default FLAGS AC_DEFUN([AX_CXXFLAGS_IRIX_OPTION_NEW], [dnl AS_VAR_PUSHDEF([FLAGS],[CXXFLAGS])dnl AS_VAR_PUSHDEF([VAR],[ac_cv_cxxflags_irix_option_$1])dnl AC_CACHE_CHECK([m4_ifval($2,$2,FLAGS) for irix/cc m4_ifval($1,$1,-option)], VAR,[VAR="no, unknown" AC_LANG_SAVE AC_LANG_CXX ac_save_[]FLAGS="$[]FLAGS" for ac_arg dnl in "-fullwarn -use_readonly_const % m4_ifval($1,$1,-option)" dnl IRIX C # do FLAGS="$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_IRIX_OPTION],[ifelse(m4_bregexp([$2],[-]),-1, [AX_CFLAGS_IRIX_OPTION_NEW($@)],[AX_CFLAGS_IRIX_OPTION_OLD($@)])]) AC_DEFUN([AX_CXXFLAGS_IRIX_OPTION],[ifelse(m4_bregexp([$2],[-]),-1, [AX_CXXFLAGS_IRIX_OPTION_NEW($@)],[AX_CXXFLAGS_IRIX_OPTION_OLD($@)])])
