cannot find -lmysqlclient

I'm trying to compile a C++ program and one of the classes uses . g++ is not able to find the libraries would be my guess. The command i use to compile is -

g++ c1.cpp c2.cpp c3.cpp c4.cpp -o c4 -lm -lmysqlclient

c3.cpp is the file that needs mysql.h. This works perfectly on my local machine, but refuses to run on the server with the error

cannot find -lmysqlclient

I tried finding the libmysqlclient.so files on the server using the find command, I don't think they are present there

uname -a

reveals

SunOS opteron 5.10 Generic_139556-08 i86pc i386 i86pc
user@opteron 12:26:02 ~/c++/projname/

I realize tha开发者_C百科t i need to link some libraries, but where and how?

Any help would be appreciated. Thanks.

Whatever library packages u think is not installed can be installed using sudo apt-get install. But the problem is to find the right name of the package apt-get can understand. So how to do that ?! simple

use command : sudo apt-cache search <filename>

For eg.: in this case lmysqlclient

sudo apt-cache search mysqlclient

(remember to exclude 'l' from the actual name ,ie, mysqlclient and not lmysqlclient). This outputs:

libmysqlclient-dev - MySQL database development files

In the above -libmysqlclient-dev is the name that apt-get can recognize and solve our cannot find lmysqlclient problem

so now type: sudo apt-get install libmysqlclient-dev from interface. After its done, try making your required file.

Simplifying @SriHariY.S's answer-

Try installing it with sudo apt-get install libmysqlclient-dev.

Do you have the MySQL client libraries? Can you look for it as

find / -name "libmysqlclient.so" -type f -print 2>/dev/null

Also, you can use the -R flag on linker to hardlink the libmysqlclient as

g++ -R/usr/local/mysql/lib ....

Or, you can export the LD_LIBRARY_PATH_32 or LD_LIBRARY_PATH_64 as

export LD_LIBRARY_PATH_32=$MYSQL_HOME/lib

On Ubuntu 18 I used this command to find a name of required package for fixing this error:

apt search lmysqlclient

After this I installed missing package:

sudo apt install libmariadbclient-dev-compat
