问题描述
我使用stack
创建了一个新项目,并使用resolver: lts-16.12
创建了一个项目。当使用.hs
运行示例stack runghc src/MyExample.hs
文件时,它可以正常工作,但在运行之前我也已经获得了这些文件:
/home/lpied/.stack/programs/x86_64-linux/ghc-8.8.4/lib/ghc-8.8.4/bin/ghc: /lib64/libtinfo.so.5: no version information available (required by /home/lpied/.stack/programs/x86_64-linux/ghc-8.8.4/lib/ghc-8.8.4/bin/../haskeline-0.7.5.0/libHShaskeline-0.7.5.0-ghc8.8.4.so)
/home/lpied/.stack/programs/x86_64-linux/ghc-8.8.4/lib/ghc-8.8.4/bin/ghc: /lib64/libtinfo.so.5: no version information available (required by /home/lpied/.stack/programs/x86_64-linux/ghc-8.8.4/lib/ghc-8.8.4/bin/../ghc-8.8.4/libHSghc-8.8.4-ghc8.8.4.so)
/home/lpied/.stack/programs/x86_64-linux/ghc-8.8.4/lib/ghc-8.8.4/bin/ghc: /lib64/libtinfo.so.5: no version information available (required by /home/lpied/.stack/programs/x86_64-linux/ghc-8.8.4/lib/ghc-8.8.4/bin/../terminfo-0.4.1.4/libHSterminfo-0.4.1.4-ghc8.8.4.so)
我已经读过诸如this之类的东西,并且可以确认所涉及的库:
$ ll /lib64/libtinfo.so.5
lrwxrwxrwx. 1 root root 15 Aug 08 19:47 /lib64/libtinfo.so.5 -> libtinfo.so.5.9
没有VERDEF
/ .gnu.version_d
:
$ readelf -V /lib64/libtinfo.so.5|grep gnu
Version symbols section '.gnu.version' contains 245 entries:
Version needs section '.gnu.version_r' contains 1 entries:
似乎上面的消息已打印by this:
if (__glibc_unlikely (map->l_info[VERSYMIDX (DT_VERDEF)] == NULL))
{
/* The file has no symbol versioning. I.e.,the dependent
object was linked against another version of this file. We
only print a message if verbose output is requested. */
if (verbose)
{
/* XXX We cannot translate the messages. */
_dl_exception_create_format
(&exception,DSO_FILENAME (map->l_name),"no version information available (required by %s)",name);
goto call_cerror;
}
return 0;
}
我尝试设置/取消设置here中的各种标志,例如LD_VERBOSE
,LD_DEBUG
,LD_WARN
,但是没有任何作用。
我没有安装任何文件的权限来修复库本身。知道是否可以/如何代替这些消息吗?还是任何其他非侵入式修复程序?
解决方法
您正在使用的发行版似乎已构建了没有符号版本控制的ncurses。我猜这是Fedora派生的,所以我提交了一个错误来更改它:
同时,您可以自己构建ncurses,可能使用
./configure --prefix=/home/lpied/opt/ncurses --with-versioned-syms
make
make install
这不需要root特权。
然后在您的shell配置中将/home/lpied/opt/ncurses/lib64
添加到LD_LIBRARY_PATH
。
