Hi everyone, I'm really new to pascal and lazarus,
I'm a web designer not very skilled one in this paradigm of
programming, but try to learn.

Problem is when i try to put connection True on a database Mysql with
5.5  connector
i recive error: Cannot load default MySQL library:
libmysqlclient.18.dylib

I had read several post on this forum with same problem, and try to
adopt some solution.

I try to made a sym link from
/urs/local/mysql-5.6.11-osx10.7-x86_64/lib/ where actualy is my MySql
lib: libmysqlclient.18.dylib to /usr/lib/

I read in some case it solve the problem not for me.

Some times I see also istruction say I need to recompile Lazarus, and
dont know how to doit.

Hope some one can help

My Mac is 10.8.3
MySql version is 5.6 (i'm using connector 5.5)
Lazarus 1.0.14

lazarus-1.0.14-20131116-i386-macosx.dmg
fpc-2.6.2.intel-macosx.dmg
fpcsrc-2.6.2-i386-macosx.dmg

You are creating a 32-bit application it seems (i386-macosx),  but
your mysqlclient library seems to be 64-bit (-x86_64).

Solution: install the 32-bit client lib.

It work!

I need to download tha version 5.5 becouse when i try 5.6 even at
32-bit with connector 5.5 dose not work, and present me an error
message asking for 5.5

Than for avoid installing mysql 5.5 on my machine, becouse i need only
client lib to access database on a remote server, i copy in the folder
/usr/lib/ only the file:
libmysqlclient.18.dylib
and the symlink:
libmysqlclient.dylib

Restart Lazarus and It work! No error message when i set True on the
connection!

Thank you!
