错误现象:
cygwin下make编译crosstool-ng出错:
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $ make LDFLAGS="-lintl" GEN 'config/configure.in' GEN 'paths.mk' GEN 'paths.sh' 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' lxdialog/menubox.o:menubox.c:(.text+0x7d): undefined reference to `_wattrset' lxdialog/menubox.o:menubox.c:(.text+0x97): undefined reference to `_wmove' ...... mconf.o:mconf.c:(.text+0x13de): undefined reference to `_ncwrap_stdscr' mconf.o:mconf.c:(.text+0x13e6): undefined reference to `_getcurx' collect2: ld returned 1 exit status Makefile:100: recipe for target `mconf' failed make[2]: *** [mconf] 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$
原因:
Cygwin下虽然已经安装了ncurses库,但是此处make编译的时候,没有链接进去,所以报错。
解决办法:
参见:第 5.1.2.1 节 “zconf.tab.o:zconf.tab.c:(.text+0x162a): undefined reference to ‘_libintl_gettext'”中的此处也同时添加了ncurses库,解决了undefined reference to `_wattrset'的问题,去修改makefile而解决。
注意:参见之前此处不要通过make时加LDFLAGS参数去添加-lintl和-lcurses的解释,不要通过给make加LDFLAGS的方式去解决此问题,而是如上,使用修改makefile去解决此问题。
