Collect2: LD returned 1 exit status

The reason is that the mysqlclient library is not linked during compilation.

Correct Solution: GCC testmysql. C-lmysqlclient

2. the following error occurs during compilation: Fatal error: mysql. h: no such file or directory.
But in the source file # include <mysql. h> what is going on?

Find out where the mysql. h file is located,

Locate mysql. h

/Usr/include/MySQL. h
It is not in the include directory, so change # include <mysql. h> in the source file to # include <MySQL/musql. h>.

OK.
