我第一次尝试在ncurses中进行实验,但在编译源代码时遇到了问题。据我所知,ncurses已安装并位于正确的目录中。
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
$ locate ncurses.h
/usr/include/ncursesw/ncurses.h
$ dpkg -l | grep ncurses
ii libncurses5:amd64 5.9+20140118-1ubuntu1 amd64 shared libraries for terminal handling
ii libncursesw5:amd64 5.9+20140118-1ubuntu1 amd64 shared libraries for terminal handling (wide character support)
ii libncursesw5-dev:amd64 5.9+20140118-1ubuntu1 amd64 developer's libraries for ncursesw
ii mtr-tiny 0.85-2 amd64 Full screen ncurses traceroute tool
ii ncurses-base 5.9+20140118-1ubuntu1 all basic terminal type definitions
ii ncurses-bin 5.9+20140118-1ubuntu1 amd64 terminal-related programs and man pages
ii ncurses-term 5.9+20140118-1ubuntu1 all additional terminal type definitions
但当我尝试
bankacct.cpp:18:29: fatal error: ncurses.h: No such file or directory
compilation terminated.
我试过包括
<ncursesw/ncurses.h>
基于其他用户的建议,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
它给了我这个:
$ 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'
现在我已经尝试链接这些库。以下是我所做的:
$ 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
因此,我尝试了两种makefile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
这仍然给了我错误
undefined reference to 'initscr'
(无
-Incurses公司
)或
/usr/bin/ld: cannot find -lncurses
(有了它)
