[【背景】
之前折腾过了：
【已解决】Cygwin下make编译crosstool-ng出错：nconf.o:nconf.c:(.text+0×373): undefined reference to `_free_item’
虽然问题已解决，且已经把相关内容整理到了：
zconf.tab.o:zconf.tab.c:(.text+0x162a): undefined reference to ‘_libintl_gettext’
中，但是，其根本原因，还是未知。
此处，想要继续去研究一下。
目前能想到的是：
针对：
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $ make LDFLAGS="-lintl -lcurses"
再去再去研究一下：
（1）是否是由于：
make LDFLAGS="-lintl -lcurses"
和：
$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses nconf: LDFLAGS += -lmenu -lpanel -lncurses
冲突，是由于：
make的LDFLAGS中加的是curses，而makefile中加的是ncurses
而使得，同时使用curses和ncurses，就会出现类似的问题？
（2）或者是：
make不加参数的情况下，即直接：
make
然后makefile中，从：
$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses nconf: LDFLAGS += -lmenu -lpanel -lncurses
改为：
$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses $(INTL_CFLAGS) nconf: LDFLAGS += -lmenu -lpanel -lncurses
就会出现同样问题？？？
（3）又或是，我之前是把：
make LDFLAGS="-lintl -lncurses"
错写成了：
make LDFLAGS="-lintl -lcurses"
即，本来该是ncurses错写成了curses，而导致了此处的错误？
【折腾过程】
1.目测，感觉第二种更可疑。
所以先去看看效果。
先去make clean了一下：
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0_build $ ct-ng clean CLEAN config CLEAN config.gen CLEAN log
汗，搞错了，应该是去crosstool-ng 的源码的文件夹中去make clean：

然后去修改：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0\kconfig\Makefile
改为：
#$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses $(INTL_CFLAGS) #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses/ $(INTL_CFLAGS) $(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses/ nconf: LDFLAGS += -lintl -lmenu -lpanel -lncurses
然后再去make试试，结果是可以的：
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $ make SED 'ct-ng' SED 'scripts/crosstool-NG.sh' SED 'scripts/saveSample.sh' SED 'scripts/showTuple.sh' GEN 'config/configure.in' GEN 'paths.mk' GEN 'paths.sh' DEP 'nconf.gui.dep' DEP 'nconf.dep' DEP 'lxdialog/checklist.dep' DEP 'lxdialog/inputbox.dep' DEP 'lxdialog/util.dep' DEP 'lxdialog/textbox.dep' DEP 'lxdialog/yesno.dep' DEP 'lxdialog/menubox.dep' DEP 'mconf.dep' DEP 'conf.dep' BISON 'zconf.tab.c' GPERF 'zconf.hash.c' LEX 'lex.zconf.c' DEP 'zconf.tab.dep' CC 'zconf.tab.o' CC 'conf.o' LD 'conf' CC 'lxdialog/menubox.o' CC 'lxdialog/yesno.o' CC 'lxdialog/textbox.o' CC 'lxdialog/util.o' CC 'lxdialog/inputbox.o' CC 'lxdialog/checklist.o' CC 'mconf.o' LD 'mconf' CC 'nconf.o' CC 'nconf.gui.o' LD 'nconf' SED 'docs/ct-ng.1' GZIP 'docs/ct-ng.1.gz' Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $
所以说明：
此处，不是由于
CFLAGS +=
的时候，路径：
$(INTL_CFLAGS)
和
-I/usr/include/ncurses/
颠倒就会出错，此处的两者的顺序是无关的。
2.那再去试试，再改：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0\kconfig\Makefile
回原来的：
#$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses $(INTL_CFLAGS) $(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses/ $(INTL_CFLAGS) #$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses/ nconf: LDFLAGS += -lintl -lmenu -lpanel -lncurses
但是make时LDFLAGS中添加lcurses（而估计不是lncurses）。
结果，会出现找不到“_libintl_gettext”的情况：

3.再去加上-lintl试试：

5.然后把LDFLAGS中的curses换成ncurses试试：
结果也是问题依旧，是那个“_free_item”的错误：

6.看来，的确是LDFLAGS添加了-lintl后，就导致了此问题的出现。
那看起来应该是：
makefile中，都已经是：
# lxdialog source files LX_SRC = $(wildcard lxdialog/*.c) LX_OBJ = $(patsubst %.c,%.o,$(LX_SRC)) LX_DEP = $(patsubst %.o,%.dep,$(LX_OBJ)) $(LX_OBJ) $(LX_DEP): CFLAGS += $(NCURSES_CFLAGS) $(INTL_CFLAGS) # What's needed to build 'conf' conf_SRC = conf.c conf_OBJ = $(patsubst %.c,%.o,$(conf_SRC)) conf_DEP = $(patsubst %.o,%.dep,$(conf_OBJ)) $(conf_OBJ) $(conf_DEP): CFLAGS += $(INTL_CFLAGS) conf: LDFLAGS += -lintl # What's needed to build 'mconf' mconf_SRC = mconf.c mconf_OBJ = $(patsubst %.c,%.o,$(mconf_SRC)) mconf_DEP = $(patsubst %.c,%.dep,$(mconf_SRC)) $(mconf_OBJ) $(mconf_DEP): CFLAGS += $(NCURSES_CFLAGS) $(INTL_CFLAGS) #mconf: LDFLAGS += $(NCURSES_LDFLAGS) mconf: LDFLAGS += -lintl $(NCURSES_LDFLAGS) # What's needed to build 'nconf' nconf_SRC = nconf.c nconf.gui.c nconf_OBJ = $(patsubst %.c,%.o,$(nconf_SRC)) nconf_DEP = $(patsubst %.c,%.dep,$(nconf_SRC)) #$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses $(INTL_CFLAGS) $(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses/ $(INTL_CFLAGS) #$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses/ nconf: LDFLAGS += -lintl -lmenu -lpanel -lncurses
感觉LDFLAGS都已经nconf的前面，在conf，mconf时，都已经添加过了对应的-lintl，也算-lintl加了2此了
加上nconf这次，LDFLAGS中，都加了3次的-lintl了，
此处，即使是从make传入的LDFLAGS中，再添加一次，也还是，无谓的，加了4次的-lintl而已，
即，在3次的-lintl基础上再加一次，应该不影响才对。
7.不过，才发现，此处是：
针对于conf，mconf，nconf，其实都只是依赖于自己当前的LDFLAGS，即：
conf，mconf，nconf对应的LDFLAGS，都是独立的，
所以，前面的-lintl，都只是加了一次而已。
8.但是，为何其他两个，即conf和mconf，也都在LDFLAGS中，加了对应的-lintl了，都可以正常编译，
唯独此处的nconf，从make中得到传入的LDFLAGS中，含有-lintl，然后加上自己当前的：
-lintl -lmenu -lpanel –lncurses
就出错了呢？
9.看到：
nconf.o:nconf.c:(.text+0x373): undefined reference to `_free_item' nconf.o:nconf.c:(.text+0x3cc): undefined reference to `_current_item' nconf.o:nconf.c:(.text+0x3d4): undefined reference to `_item_index'
突然想起来了，可以去看看对应的nconf.c中的源码：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0\kconfig\nconf.c
看看是否调用到了这些函数。
结果是：
（1）_free_item
没找到。
但是找到了free_item：
static void clean_items(void)
{
int i;
for (i = 0; curses_menu_items[i]; i++)
free_item(curses_menu_items[i]);
bzero(curses_menu_items, sizeof(curses_menu_items));
bzero(k_menu_items, sizeof(k_menu_items));
items_num = 0;
}
/* very hackish. adds a string to the last item added */
static void item_add_str(const char *fmt, ...)
{
va_list ap;
int index = items_num-1;
......
free_item(curses_menu_items[index]);
curses_menu_items[index] = new_item(
k_menu_items[index].str,
k_menu_items[index].str);
set_item_userptr(curses_menu_items[index],
&k_menu_items[index]);
}（2）_current_item
没找到。
但是找到了一堆对于：current_item，的调用。
（3）然后对于其他的，也是类似的，
比如：
_set_item_userptr
找不到，但是可以找到：
set_item_userptr
10.再去试试，把makefile中include路径再变化一下，改为：
#$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses $(INTL_CFLAGS) #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses/ $(INTL_CFLAGS) $(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses/ nconf: LDFLAGS += -lintl -lmenu -lpanel -lncurses
然后再去用make的LDFLAGS中包含-lintl -lncurses去试试结果：
结果错误依旧：

只能说明：
make的LDFLAGS包含了-lintl，
此处makefile中LDFLAGS也包含了-lintl的话，
就比如出现上面这个”_free_item”的错误。
但是原因还是没搞懂。
11.再去试试，make传递进入的LDFLAGS中，只有-lncurses，没有-lintl试试：
结果是：
会出现那个“_libintl_gettext”的问题：

所以，也很是奇怪。
12.再去把make的LDFLAGS中的-lncurses改为-lcurses：
结果问题如上，同样是”_libintl_gettext”的错误：
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $ make LDFLAGS="-lcurses" SED 'ct-ng' SED 'scripts/crosstool-NG.sh' SED 'scripts/saveSample.sh' SED 'scripts/showTuple.sh' GEN 'config/configure.in' GEN 'paths.mk' GEN 'paths.sh' DEP 'nconf.gui.dep' DEP 'nconf.dep' DEP 'lxdialog/checklist.dep' DEP 'lxdialog/inputbox.dep' DEP 'lxdialog/util.dep' DEP 'lxdialog/textbox.dep' DEP 'lxdialog/yesno.dep' DEP 'lxdialog/menubox.dep' DEP 'mconf.dep' DEP 'conf.dep' BISON 'zconf.tab.c' GPERF 'zconf.hash.c' LEX 'lex.zconf.c' DEP 'zconf.tab.dep' CC 'zconf.tab.o' CC 'conf.o' LD 'conf' zconf.tab.o:zconf.tab.c:(.text+0x162a): undefined reference to `_libintl_gettext' zconf.tab.o:zconf.tab.c:(.text+0x47fe): undefined reference to `_libintl_gettext' zconf.tab.o:zconf.tab.c:(.text+0x56ec): undefined reference to `_libintl_gettext' zconf.tab.o:zconf.tab.c:(.text+0x58be): undefined reference to `_libintl_gettext' zconf.tab.o:zconf.tab.c:(.text+0xc70b): undefined reference to `_libintl_gettext' zconf.tab.o:zconf.tab.c:(.text+0xc719): more undefined references to `_libintl_gettext' follow /usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../../i686-pc-cygwin/bin/ld: zconf.tab.o: bad reloc address 0x110 in section `.data' /usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../../i686-pc-cygwin/bin/ld: final link failed: Invalid operation collect2: ld 返回 1 Makefile:113: recipe for target `conf' failed make[2]: *** [conf] Error 1 Makefile:160: recipe for target `build-lib-kconfig' failed make[1]: *** [build-lib-kconfig] Error 2 Makefile:120: recipe for target `build' failed make: *** [build] Error 2 Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $
13.再去把makefile中，-lintl和-lncurses都去掉，变成：
#$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses $(INTL_CFLAGS) #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses/ $(INTL_CFLAGS) $(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses/ #nconf: LDFLAGS += -lintl -lmenu -lpanel -lncurses nconf: LDFLAGS += -lmenu -lpanel
然后make时LDFLAGS中，再传入对应的-lintl和-lncurses，试试效果：
结果出现之前的那个”_free_item”的错误：

14.截止目前，真的是没有完全搞懂，为何会出现这种，
至少看起来，很奇怪的现象。
还是把makefile文件：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0\kconfig\Makefile
改为原先的：
#$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses #$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses $(INTL_CFLAGS) $(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses/ $(INTL_CFLAGS) #$(nconf_OBJ) $(nconf_DEP): CFLAGS += $(INTL_CFLAGS) -I/usr/include/ncurses/ nconf: LDFLAGS += -lintl -lmenu -lpanel -lncurses #nconf: LDFLAGS += -lmenu -lpanel
然后make中不指定参数的去编译：
最终就是可以的了：
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $ make SED 'ct-ng' SED 'scripts/crosstool-NG.sh' SED 'scripts/saveSample.sh' SED 'scripts/showTuple.sh' GEN 'config/configure.in' GEN 'paths.mk' GEN 'paths.sh' DEP 'nconf.gui.dep' DEP 'nconf.dep' DEP 'lxdialog/checklist.dep' DEP 'lxdialog/inputbox.dep' DEP 'lxdialog/util.dep' DEP 'lxdialog/textbox.dep' DEP 'lxdialog/yesno.dep' DEP 'lxdialog/menubox.dep' DEP 'mconf.dep' DEP 'conf.dep' BISON 'zconf.tab.c' GPERF 'zconf.hash.c' LEX 'lex.zconf.c' DEP 'zconf.tab.dep' CC 'zconf.tab.o' CC 'conf.o' LD 'conf' CC 'lxdialog/menubox.o' CC 'lxdialog/yesno.o' CC 'lxdialog/textbox.o' CC 'lxdialog/util.o' CC 'lxdialog/inputbox.o' CC 'lxdialog/checklist.o' CC 'mconf.o' LD 'mconf' CC 'nconf.o' CC 'nconf.gui.o' LD 'nconf' SED 'docs/ct-ng.1' GZIP 'docs/ct-ng.1.gz' Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $
【总结】
截止目前，已知的是：
（1）关于出现”_free_item”的错误：
当makefile中（nconf的）LDFLAGS包含了-lintl，
然后make时传入的LDFLAGS也包含了-lintl的话，
就一定会出现这个”_free_item”的错误。
（2）关于出现“_libintl_gettext”的问题：
make传递进入的LDFLAGS中，只有-lncurses，没有-lintl试试：
则又会出现那个“_libintl_gettext”的问题
（3）正常编译
目前只能通过：
对于nconf来说：
makefile中，正常是：
$(nconf_OBJ) $(nconf_DEP): CFLAGS += -I/usr/include/ncurses/ $(INTL_CFLAGS) nconf: LDFLAGS += -lintl -lmenu -lpanel -lncurses
然后编译的时候，make不指定任何参数：
make
去编译，就是正常的。
具体上述现象的根本原因，至今未搞明白。
