Mocp: Error while loading shared libraries: libltdl. so.3: cannot open shared object file: no such file or directory

This is depressing. After a few times of Google, I found that a foreign website said a bug, saying that the upgraded ImageMagick would appear, but it takes 05 years to submit the bug, it's been 09 years now. It's impossible. Later, I found that someone on the internet is using a great deal of tricks.

# Ln-S/usr/lib/libltdl. So/usr/lib/libltdl. so.3

Then exit X and re-enter. Everything is normal, so you can write this blog now.
