GreateSQL命令行无法使用Backspace和Delete键
本帖最后由 yushao21 于 2025-7-4 17:09 编辑今天根据官方文档：https://greatsql.cn/docs/8.0.32- ... ubuntu-install.html 的指引，安装了GreateSQL，安装好后，用命令行登录，发现无法通过退格键删除字母，delete键也没用，加了ctrl一起也没用，不知道啥问题。检查系统包是安装了readline的。

我用的CENTOS 7，数据库版本是Server version: 8.0.32-25 GreatSQL (GPL), Release 25, Revision 79f57097e3f。删除键和退格键是正常的 搜索是否有 /usr/local/GreatSQL-8.0.32-27-Linux-glibc2.28-x86_64/lib/private/libreadline.so 这个动态库文件，将其加到 ldconfig path 里，再试试看呢，以下是大概示例

经查，应该是和 libncurses.so 、 libtinfo.so 这两个动态库有关系，用 glibc 2.17 包里的这两个文件替换过来就可以正常回档删除了
也就是说，在GreatSQL的CI编译环境中，glibc 2.28环境中的libncurses库不适用于Ubuntu 22.04环境
libncurses.so是Linux终端处理的核心库，负责光标移动、窗口创建、颜色显示等功能，像vim、htop这些工具都依赖它。而libtinfo.so更轻量，主要处理终端转义序列的解析和终端能力描述，通常作为libncurses的依赖存在

原来如此，是不是其它国产操作系统也会这样？ reddey 发表于 2025-7-8 19:44
原来如此，是不是其它国产操作系统也会这样？
和OS没关系，而是和curses库的版本有关系，我测了下，似乎只有6.1这个版本会这样，高于、低于这个版本都正常 yejr 发表于 2025-7-9 08:46
