我正在尝试安装 Oleo (http://www.gnu.org/software/oleo/) 在 Cygwin 设置上遇到了一些问题。在链接阶段，构建出错，抱怨 ncurses 中未定义的引用。我安装了 libncurses-devel 包。
我运行的构建命令是：
me@mymachine$ CFLAGS="-I/usr/include/ncurses" ./configure
[configure chatter, then success]
me@mymachine$ CFLAGS="-I/usr/include/ncurses" make
[snip successful compile...]

有谁知道是什么原因导致了这些 ncurses 问题？

您可能需要将-lcurses或-lncurses添加到 CFLAGS 才能成功编译。
