				Was netxms compiled? Try adding --with-mysql to ./configure command. There's also ./configure --help that might be helpful. 
			
			
			
				Hi Sudanov.
Yes, it was compiled with the following commands : 
./configure --prefix=/produtos/netxms --with-server --with-mysql --with-agent --disable-ssh --disable-mqtt
./make install -I /produtos/netxms
./make -I /produtos/netxms
			
			
			
				Try installing mysql-libs package. 
Also, it could be easier to use Debian or Ubuntu, as we provide packages for these systems.

Sudanov
