我对“Brother MFC-660CN 打印机”设置上的符号链接有疑问和困惑
我通过 Brother 网站的安装文件安装了驱动程序
该文件是“linux-1.0-installer-brfax”
安装一切正确，没有错误......
但在/var/log/sys.log或引导出现这个：
FX6300 udevd[412]: unknown key 'SYSFS{idVendor}' in /etc/udev/rules.d/40-brother-libsane-type1.rules:17
FX6300 udevd[412]: invalid rule '/etc/udev/rules.d/40-brother-libsane-type1.rules:17'
在文件中/etc/udev/rules.d/40-brother-libsane-type1.rules我有这个：

当我从终端安装任何东西时我也遇到这个错误：
/sbin/ldconfig.real: /usr/lib/libbrcolm2.so.1 is not a symbolic link
/sbin/ldconfig.real: /usr/lib/libbrscandec2.so.1 is not a symbolic link
当我使用ls -l命令我有这个：
$ ls -l /usr/lib/libbrscandec2.so

-rwxr-xr-x 1 root root 15072 Dez 2 2009 /usr/lib64/libbrcolm2.so.1.0.1
我不知道我的想法是否正确但是......
在文件夹中：
/usr/lib64/
符号链接来自：
库到库并结束于libbrscandec2.so.1.0.0？
同样适用于libbcolm2库？
据我从其他帖子了解，符号链接位于文件夹之间：
/usr/lib/和/usr/lib64/
还是我的想法错了？这里出了什么问题？
我非常感谢任何对此的帮助。
谢谢。
答案1
解决了我的问题...
我发表评论/etc/udev/rules.d/40-brother-libsane-type1.rules：
#SYSFS{idVendor}=="04f9", GOTO="brother_mfp_udev_2" <<<<< here
ATTRS{idVendor}=="04f9", GOTO="brother_mfp_udev_2"
GOTO="brother_mfp_end" LABEL="brother_mfp_udev_2"
也许是SYSFS{供应商标识}和ATTRS{供应商编号}因为它们是相同的“04f9”?? 只是猜测……
并且 simlink 在/etc/lib/
libbrscandec2.so > libbrscandec2.so.1 > libbrscandec2.so.1.0.0
并libbcolm2库也喜欢库文件
错误不再出现...
效果确实很好...

升级到 saucy 后，我开始收到相同的 ldconfig 符号链接错误。您可以手动编辑符号链接，如下所示lc1975或者直接删除并重新安装brscan2封装（可用这里）。
libbrscandec2 和 libbrcolm2 均由brscan2deb 来自 Brother，它们是包中的符号链接：
