Solutions to Common Errors in linux

Solution to a common type of errors in linux-general Linux technology-Linux programming and kernel information. For details, refer to the following section. When compiling the source code, the following errors often occur:
/Usr/bin/ld: cannot find-libutempter
What is more common is
/Usr/bin/ld: cannot find-l ***
The stars below indicate a type of incorrect name. The cause of this error is very simple, that is, Link error. The simple method is to manually set the link once and take
/Usr/bin/ld: cannot find-libutempter
For example:
Now let's take a look at the format of the class library file under the lib Folder:
Cd/usr/lib
Ls-la | grep iutempter
The result is as follows:
Lrwxrwxrwx 1 root 20 09-10 :26 libutempter. so.0-> libutempter. so.1.1.4
-Rwxr-xr-x 1 root 6216 libutempter. so.1.1.4
Obviously, there is no. so file. We can link a. so file again.
Ln-s libutempter. so.0 libutempter. so
Can I compile it again?

And, for example
/Usr/bin/ld: cannot find-lelf
It is also a type. Execute a link in the lib Folder:
Ln-s/usr/lib/libelf. so.1/usr/lib/libelf. so
Assume that the. so.1 library file exists.

Also:
/Usr/bin/ld: cannot find-lc
This is because libc. so does not exist.
Also, a link to libc. so is provided.
