记录如何解决error while loading shared libraries: libncurses.so

简单记录下在执行 make menuconfig过程中的下述报错：

zhushy@ubuntu:~/openharmony/kernel/liteos_a$ make menuconfig
/home/zhushy/openharmony/kernel/liteos_a/tools/menuconfig/mconf /home/zhushy/openharmony/kernel/liteos_a/Kconfig
/home/zhushy/openharmony/kernel/liteos_a/tools/menuconfig/mconf: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory
make: *** [Makefile:140: menuconfig] Error 127

......

root@ubuntu:/home/zhushy/openharmony/kernel/liteos_a# make menuconfig
/home/zhushy/openharmony/kernel/liteos_a/tools/menuconfig/mconf /home/zhushy/openharmony/kernel/liteos_a/Kconfig
/home/zhushy/openharmony/kernel/liteos_a/tools/menuconfig/mconf: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
make: *** [Makefile:140: menuconfig] Error 127

1、出现问题的环境

使用vmware worstation安装的Ubuntu 21.04：

root@ubuntu:/home/zhushy/openharmony/kernel/liteos_a# cat /etc/*release*
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=21.04
DISTRIB_CODENAME=hirsute
DISTRIB_DESCRIPTION="Ubuntu 21.04"

UBUNTU_CODENAME=hirsute

2、解决步骤

2.1 搜索找不到库文件的位置

• 执行如下命令find / -name *ncurse*查找libncurses.so.5的位置：

root@ubuntu:/home/zhushy/openharmony/kernel/liteos_a# find / -name *ncurse*
...
/snap/core18/1997/lib/x86_64-linux-gnu/libncurses.so.5
/snap/core18/1997/lib/x86_64-linux-gnu/libncurses.so.5.9
/snap/core18/1997/lib/x86_64-linux-gnu/libncursesw.so.5
/snap/core18/1997/lib/x86_64-linux-gnu/libncursesw.so.5.9
/snap/core18/1997/usr/share/doc/libncurses5
/snap/core18/1997/usr/share/doc/libncursesw5
/snap/core18/1997/usr/share/doc/ncurses-base
/snap/core18/1997/usr/share/doc/ncurses-bin
/snap/core18/1997/usr/share/lintian/overrides/ncurses-base
/snap/core18/2074/lib/x86_64-linux-gnu/libncurses.so.5
/snap/core18/2074/lib/x86_64-linux-gnu/libncurses.so.5.9
/snap/core18/2074/lib/x86_64-linux-gnu/libncursesw.so.5
/snap/core18/2074/lib/x86_64-linux-gnu/libncursesw.so.5.9
/snap/core18/2074/usr/share/doc/libncurses5
/snap/core18/2074/usr/share/doc/libncursesw5
/snap/core18/2074/usr/share/doc/ncurses-base
/snap/core18/2074/usr/share/doc/ncurses-bin
/snap/core18/2074/usr/share/lintian/overrides/ncurses-base
find: ‘/run/user/1000/gvfs’: Permission denied

• 执行如下命令find / -name *libtinfo*查找libtinfo.so.5的位置：

root@ubuntu:/home/zhushy/openharmony/kernel/liteos_a# find / -name *libtinfo*                                                                                 
/snap/core18/1997/lib/x86_64-linux-gnu/libtinfo.so.5
/snap/core18/1997/lib/x86_64-linux-gnu/libtinfo.so.5.9
/snap/core18/1997/usr/share/doc/libtinfo5
/snap/core18/2074/lib/x86_64-linux-gnu/libtinfo.so.5
/snap/core18/2074/lib/x86_64-linux-gnu/libtinfo.so.5.9
/snap/core18/2074/usr/share/doc/libtinfo5
find: ‘/run/user/1000/gvfs’: Permission denied

通过检索，可以尝试使用下如下的文件：

• /snap/core18/1997/lib/x86_64-linux-gnu/libncurses.so.5.9
• /snap/core18/1997/lib/x86_64-linux-gnu/libncursesw.so.5.9
• /snap/core18/1997/lib/x86_64-linux-gnu/libtinfo.so.5.9

2.2 为找到的库文件创建软链接

执行如下命令创建软链接：

 ln -s /snap/core18/1997/lib/x86_64-linux-gnu/libncurses.so.5.9 /usr/lib/x86_64-linux-gnu/libncurses.so.5
ln -s /snap/core18/1997/lib/x86_64-linux-gnu/libncursesw.so.5.9 /usr/lib/x86_64-linux-gnu/libncursesw.so.5.9
ln -s /snap/core18/1997/lib/x86_64-linux-gnu/libtinfo.so.5.9 /usr/lib/x86_64-linux-gnu/libtinfo.so.5

重新执行make menunconfig,即可正常工作：
