如图：
即：
| scripts/kconfig/lxdialog/checklist.o:checklist.c:(.text+0x31): undefined reference to `wmove’ |
【解决过程】
1.此人遇到类似问题：
Missing symbols in libncurses?
但是无解。
2.google搜：
cygwin bad reloc address 0x20 in section
倒是可以搜到很多，但是好像也太大帮助。
3.搜：
cygwin scripts/kconfig/lxdialog/checklist.o:checklist.c
参考：
Re: [arm-gnu] cygwin / arm-none-linux-gnueabi kernel build error
去试试：
make HOST_LOADLIBES="-lcurses -lintl" menuconfig
结果就可以了。
CLi@PC-CLI-1 ~/develop/kernel/linux-2.6.19.1 $ make HOST_LOADLIBES="-lcurses -lintl" menuconfig HOSTCC scripts/basic/fixdep scripts/basic/fixdep.c: In function ‘parse_config_file’: scripts/basic/fixdep.c:242:4: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/fixdep.c: In function ‘parse_dep_file’: scripts/basic/fixdep.c:319:4: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/fixdep.c: In function ‘traps’: scripts/basic/fixdep.c:371:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] scripts/basic/fixdep.c:373:4: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] HOSTCC scripts/basic/docproc scripts/basic/docproc.c: In function ‘find_export_symbols’: scripts/basic/docproc.c:188:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:191:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:197:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:200:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c: In function ‘singfunc’: scripts/basic/docproc.c:267:17: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c: In function ‘parse_file’: scripts/basic/docproc.c:300:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:305:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:310:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:316:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:319:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] HOSTLD scripts/kconfig/mconf scripts/kconfig/mconf arch/arm/Kconfig
如图：
4.说明，此处，还是和之前的：
类似，是缺少了对应的curses库。
所以，其实，觉得更好的办法，应该是，类似于：
在makefile中，检测到对应的平台是cygwin，然后添加对应的库，才是比较好的。
所以，去看看能否找到更好的解决办法。
然后，针对之前在：
linux-2.6.19.1\scripts\kconfig\Makefile
中添加的：
#ifeq (${OSTYPE},cygwin)
#HOST_LOADLIBES := -lintl
#endif
IS_CYGWIN=$(shell uname | grep -i cygwin > /dev/null 2>&1 && echo yes || echo no)
ifeq ($(IS_CYGWIN),yes)
HOST_LOADLIBES += -lintl
endif去分析：
CLi@PC-CLI-1 ~/develop/kernel/linux-2.6.19.1
$ uname | grep -i cygwin
CYGWIN_NT-6.1-WOW64
CLi@PC-CLI-1 ~/develop/kernel/linux-2.6.19.1
$ grep --help
Usage: grep [OPTION]... PATTERN [FILE]...
Search for PATTERN in each FILE or standard input.
PATTERN is, by default, a basic regular expression (BRE).
Example: grep -i 'hello world' menu.h main.c
Regexp selection and interpretation:
-E, --extended-regexp PATTERN is an extended regular expression (ERE)
-F, --fixed-strings PATTERN is a set of newline-separated fixed strings
-G, --basic-regexp PATTERN is a basic regular expression (BRE)
-P, --perl-regexp PATTERN is a Perl regular expression
-e, --regexp=PATTERN use PATTERN for matching
-f, --file=FILE obtain PATTERN from FILE
-i, --ignore-case ignore case distinctions
-w, --word-regexp force PATTERN to match only whole words
-x, --line-regexp force PATTERN to match only whole lines
-z, --null-data a data line ends in 0 byte, not newline
Miscellaneous:
-s, --no-messages suppress error messages
-v, --invert-match select non-matching lines
-V, --version print version information and exit
--help display this help and exit
--mmap ignored for backwards compatibility
Output control:
-m, --max-count=NUM stop after NUM matches
-b, --byte-offset print the byte offset with output lines
-n, --line-number print line number with output lines
--line-buffered flush output on every line
-H, --with-filename print the filename for each match
-h, --no-filename suppress the prefixing filename on output
--label=LABEL print LABEL as filename for standard input
-o, --only-matching show only the part of a line matching PATTERN
-q, --quiet, --silent suppress all normal output
--binary-files=TYPE assume that binary files are TYPE;
TYPE is `binary', `text', or `without-match'
-a, --text equivalent to --binary-files=text
-I equivalent to --binary-files=without-match
-d, --directories=ACTION how to handle directories;
ACTION is `read', `recurse', or `skip'
-D, --devices=ACTION how to handle devices, FIFOs and sockets;
ACTION is `read' or `skip'
-R, -r, --recursive equivalent to --directories=recurse
--include=FILE_PATTERN search only files that match FILE_PATTERN
--exclude=FILE_PATTERN skip files and directories matching FILE_PATTERN
--exclude-from=FILE skip files matching any file pattern from FILE
--exclude-dir=PATTERN directories that match PATTERN will be skipped.
-L, --files-without-match print only names of FILEs containing no match
-l, --files-with-matches print only names of FILEs containing matches
-c, --count print only a count of matching lines per FILE
-T, --initial-tab make tabs line up (if needed)
-Z, --null print 0 byte after FILE name
Context control:
-B, --before-context=NUM print NUM lines of leading context
-A, --after-context=NUM print NUM lines of trailing context
-C, --context=NUM print NUM lines of output context
-NUM same as --context=NUM
--color[=WHEN],
--colour[=WHEN] use markers to highlight the matching strings;
WHEN is `always', `never', or `auto'
-U, --binary do not strip CR characters at EOL (MSDOS)
-u, --unix-byte-offsets report offsets as if CRs were not there (MSDOS)
`egrep' means `grep -E'. `fgrep' means `grep -F'.
Direct invocation as either `egrep' or `fgrep' is deprecated.
With no FILE, or when FILE is -, read standard input. If less than two FILEs
are given, assume -h. Exit status is 0 if any line was selected, 1 otherwise;
if any error occurs and -q was not given, the exit status is 2.

CLi@PC-CLI-1 ~/develop/kernel/linux-2.6.19.1
$ uname | grep -i cygwin > /dev/null 2>&1 && echo yes || echo no
yes
CLi@PC-CLI-1 ~/develop/kernel/linux-2.6.19.1
$结果可以看出：
此处，IS_CYGWIN，的确生效了，是yes，所以，之前只加了对应的-lintl，所以此处，可以再去加上对应的-lcurses，应该也可以解决问题。
5.所以去改为：
#ifeq (${OSTYPE},cygwin)
#HOST_LOADLIBES := -lintl
#endif
IS_CYGWIN=$(shell uname | grep -i cygwin > /dev/null 2>&1 && echo yes || echo no)
ifeq ($(IS_CYGWIN),yes)
HOST_LOADLIBES += -lintl -lcurses
endif试试，效果也是一样的：
CLi@PC-CLI-1 ~/develop/kernel/linux-2.6.19.1 $ make menuconfig HOSTCC scripts/basic/fixdep scripts/basic/fixdep.c: In function ‘parse_config_file’: scripts/basic/fixdep.c:242:4: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/fixdep.c: In function ‘parse_dep_file’: scripts/basic/fixdep.c:319:4: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/fixdep.c: In function ‘traps’: scripts/basic/fixdep.c:371:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] scripts/basic/fixdep.c:373:4: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] HOSTCC scripts/basic/docproc scripts/basic/docproc.c: In function ‘find_export_symbols’: scripts/basic/docproc.c:188:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:191:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:197:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:200:5: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c: In function ‘singfunc’: scripts/basic/docproc.c:267:17: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c: In function ‘parse_file’: scripts/basic/docproc.c:300:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:305:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:310:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:316:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] scripts/basic/docproc.c:319:6: warning: array subscript has type ‘char’ [-Wchar-subscripts] HOSTLD scripts/kconfig/mconf scripts/kconfig/mconf arch/arm/Kconfig
即，无需在命令行中，添加HOST_LOADLIBES参数了。
【总结】
此处，在Cygwin下，交叉编译Linux时，用make menuconfig出现：
| scripts/kconfig/lxdialog/checklist.o:checklist.c:(.text+0x31): undefined reference to `wmove’ |
的错误的，
原因是：
缺少了对应的curses库，导致找不到函数而报错。
解决办法是：
在对应的Makefile：
linux-2.6.19.1\scripts\kconfig\Makefile
中，添加对应的库，即从：
IS_CYGWIN=$(shell uname | grep -i cygwin > /dev/null 2>&1 && echo yes || echo no) ifeq ($(IS_CYGWIN),yes) HOST_LOADLIBES += -lintl endif
变成：
IS_CYGWIN=$(shell uname | grep -i cygwin > /dev/null 2>&1 && echo yes || echo no) ifeq ($(IS_CYGWIN),yes) HOST_LOADLIBES += -lintl -lcurses endif
即可。
