From 64eb982edd933033879bbc8983e42149ff8f849b Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Wed, 4 Dec 2002 20:52:25 +0000 Subject: This is based on a patch posted to lkml by Petr Baudis on 23 Nov, which was then considerably hacked up by me. This eliminates the separate lxdialog and instead directly uses the lxdialog internals. This allows 'make menuconfig' to be much faster. -Erik --- extra/config/Makefile | 42 ++- extra/config/checklist.c | 363 ++++++++++++++++++++++ extra/config/colors.h | 161 ++++++++++ extra/config/dialog.h | 196 ++++++++++++ extra/config/inputbox.c | 240 +++++++++++++++ extra/config/lxdialog/BIG.FAT.WARNING | 4 - extra/config/lxdialog/Makefile | 51 ---- extra/config/lxdialog/checklist.c | 369 ---------------------- extra/config/lxdialog/colors.h | 161 ---------- extra/config/lxdialog/dialog.h | 184 ----------- extra/config/lxdialog/inputbox.c | 240 --------------- extra/config/lxdialog/menubox.c | 443 --------------------------- extra/config/lxdialog/msgbox.c | 85 ------ extra/config/lxdialog/textbox.c | 556 ---------------------------------- extra/config/lxdialog/util.c | 359 ---------------------- extra/config/lxdialog/yesno.c | 118 -------- extra/config/mconf.c | 412 ++++++++++--------------- extra/config/menubox.c | 436 ++++++++++++++++++++++++++ extra/config/msgbox.c | 85 ++++++ extra/config/textbox.c | 556 ++++++++++++++++++++++++++++++++++ extra/config/util.c | 375 +++++++++++++++++++++++ extra/config/yesno.c | 118 ++++++++ 22 files changed, 2725 insertions(+), 2829 deletions(-) create mode 100644 extra/config/checklist.c create mode 100644 extra/config/colors.h create mode 100644 extra/config/dialog.h create mode 100644 extra/config/inputbox.c delete mode 100644 extra/config/lxdialog/BIG.FAT.WARNING delete mode 100644 extra/config/lxdialog/Makefile delete mode 100644 extra/config/lxdialog/checklist.c delete mode 100644 extra/config/lxdialog/colors.h delete mode 100644 extra/config/lxdialog/dialog.h delete mode 100644 extra/config/lxdialog/inputbox.c delete mode 100644 extra/config/lxdialog/menubox.c delete mode 100644 extra/config/lxdialog/msgbox.c delete mode 100644 extra/config/lxdialog/textbox.c delete mode 100644 extra/config/lxdialog/util.c delete mode 100644 extra/config/lxdialog/yesno.c create mode 100644 extra/config/menubox.c create mode 100644 extra/config/msgbox.c create mode 100644 extra/config/textbox.c create mode 100644 extra/config/util.c create mode 100644 extra/config/yesno.c (limited to 'extra/config') diff --git a/extra/config/Makefile b/extra/config/Makefile index 383dee551..e2fc8c5a7 100644 --- a/extra/config/Makefile +++ b/extra/config/Makefile @@ -20,21 +20,37 @@ TOPDIR=../../ include $(TOPDIR)Rules.mak -all: conf mconf +all: ncurses conf mconf -NATIVE_CFLAGS=-Wall -g -O0 +#NATIVE_CFLAGS=-Wall -g -O0 +LIBS = -lncurses +ifeq (/usr/include/ncurses/ncurses.h, $(wildcard /usr/include/ncurses/ncurses.h)) + NATIVE_CFLAGS += -I/usr/include/ncurses -DCURSES_LOC="" +else +ifeq (/usr/include/ncurses/curses.h, $(wildcard /usr/include/ncurses/curses.h)) + NATIVE_CFLAGS += -I/usr/include/ncurses -DCURSES_LOC="" +else +ifeq (/usr/include/ncurses.h, $(wildcard /usr/include/ncurses.h)) + NATIVE_CFLAGS += -DCURSES_LOC="" +else + NATIVE_CFLAGS += -DCURSES_LOC="" +endif +endif +endif CONF_SRC =conf.c zconf.tab.c MCONF_SRC =mconf.c zconf.tab.c +LXDLG_SRC =checklist.c menubox.c textbox.c yesno.c inputbox.c util.c msgbox.c CONF_OBJS =$(patsubst %.c,%.o, $(CONF_SRC)) MCONF_OBJS=$(patsubst %.c,%.o, $(MCONF_SRC)) +LXDLG_OBJS=$(patsubst %.c,%.o, $(LXDLG_SRC)) conf: $(CONF_OBJS) $(NATIVE_CC) $(NATIVE_CFLAGS) $(NATIVE_LDFLAGS) $^ -o $@ -mconf: $(MCONF_OBJS) - $(NATIVE_CC) $(NATIVE_CFLAGS) $(NATIVE_LDFLAGS) $^ -o $@ +mconf: $(MCONF_OBJS) $(LXDLG_OBJS) + $(NATIVE_CC) $(NATIVE_CFLAGS) $(NATIVE_LDFLAGS) $^ -o $@ $(LIBS) lkc_deps:=lkc.h lkc_proto.h lkc_defs.h expr.h zconf.tab.h @@ -77,8 +93,24 @@ zconf.tab.h: zconf.tab.h_shipped cp zconf.tab.h_shipped zconf.tab.h endif +.PHONY: ncurses + +ncurses: + @echo "main() {}" > lxtemp.c + @if $(NATIVE_CC) lxtemp.c $(LIBS) ;
