Question

我第一次尝试在ncurses中试验，但是我在编译源代码时遇到了问题。据我所知，ncurses安装在正确的目录中。

我的makefile非常简单：

.cpp :
    g++ -Wall -g -o $* $*.cpp -std=c++11 -lncurses

这是我尝试locate ncurses.h

时的输出

$ locate ncurses.h
/usr/include/ncursesw/ncurses.h

当我检查它是否已安装时

$ dpkg -l | grep ncurses
ii  libncurses5:amd64                                     5.9+20140118-1ubuntu1                               amd64        shared libraries for terminal handling

但是当我尝试制作

时，g ++会告诉我这个

bankacct.cpp:18:29: fatal error: ncurses.h: No such file or directory
compilation terminated.

不幸的是，我没有root权限，我需要能够在这台机器上编译。我有什么选择？

我根据其他用户的建议尝试包含<ncursesw/ncurses.h>，但现在g ++给了我这个错误：

$ make bankacct
g++ -Wall -g -o bankacct bankacct.cpp -std=c++11 -lncurses
/usr/bin/ld: cannot find -lncurses

如果我尝试删除-lncurses，它会给我这个：

$ make bankacct
g++ -Wall -g -o bankacct bankacct.cpp -std=c++11
/tmp/cc8rPQfK.o: In function `main':
bankacct.cpp:23: undefined reference to `initscr'

现在我尝试连接这些库。这就是我的所作所为：

$ locate libncurse
/lib/x86_64-linux-gnu/libncurses.so.5
/lib/x86_64-linux-gnu/libncurses.so.5.9
/lib/x86_64-linux-gnu/libncursesw.so.5
/lib/x86_64-linux-gnu/libncursesw.so.5.9
/usr/lib/x86_64-linux-gnu/libncurses++w.a
/usr/lib/x86_64-linux-gnu/libncursesw.a
/usr/lib/x86_64-linux-gnu/libncursesw.so
/usr/share/doc/libncurses5
/usr/share/doc/libncursesw5
/usr/share/doc/libncursesw5-dev
/var/lib/dpkg/info/libncurses5:amd64.list
/var/lib/dpkg/info/libncurses5:amd64.md5sums
/var/lib/dpkg/info/libncurses5:amd64.postinst
/var/lib/dpkg/info/libncurses5:amd64.postrm
/var/lib/dpkg/info/libncurses5:amd64.shlibs
/var/lib/dpkg/info/libncurses5:amd64.symbols
/var/lib/dpkg/info/libncursesw5-dev:amd64.list
/var/lib/dpkg/info/libncursesw5-dev:amd64.md5sums
/var/lib/dpkg/info/libncursesw5-dev:amd64.postinst
/var/lib/dpkg/info/libncursesw5:amd64.list
/var/lib/dpkg/info/libncursesw5:amd64.md5sums
/var/lib/dpkg/info/libncursesw5:amd64.postinst
/var/lib/dpkg/info/libncursesw5:amd64.postrm
/var/lib/dpkg/info/libncursesw5:amd64.shlibs
/var/lib/dpkg/info/libncursesw5:amd64.symbols

然后我尝试了我的makefile的两个变体：

g++ -Wall -g -L/usr/lib/x86_64-linux-gnu/ -o $* $*.cpp -std=c++11 -lncurses

和

g++ -Wall -g -L/lib/x86_64-linux-gnu/ -o $* $*.cpp -std=c++11 -lncurses

仍然给我错误undefined reference to 'initscr'（没有-lncurses）或/usr/bin/ld: cannot find -lncurses（带有它）

Answer 1

-lncurses

告诉链接器查找名为＆＃34; ncurses的库。＆＃34;。你清楚地表明你的图书馆不是你的名字：

/usr/lib/x86_64-linux-gnu/libncursesw.a

你需要

-lncursesw

您不需要修改源代码以指定<ncursesw/ncurses.h>您只需添加

-I/usr/include/ncursesw

g ++虽然安装了
