Qt compile issue w/ MySQL - Mac OS X

Question

Including mysql and creating a connection in Qt gives me compile problems:

MYSQL* conn;
conn = mysql_init(NULL);

If I manually qmake and then make, I see that mysql isn't being properly linked:

qmake -o Makefile "INCLUDEPATH+=/usr/local/Cellar/mysql/5.1.54/include" "LIBS+=/usr/local/Cellar/mysql/5.1.54/lib/mysql/libmysqlclient.a"

Undefined symbols: "_mysql_init", referenced from: _main in main.o ld: symbol(s) not found collect2: ld returned 1 exit status

What is the proper method for linking mysql to my Qt project?

LIBS+="-L/usr/local/Cellar/mysql/5.1.54/lib/mysql/ -lmysqlclient.a"

Also I'm not sure but Qt by default generates pbproj instead of Makefiles.

Almost right. I was able to get the correct lib name by typing 'mysql_config --libs' This was the path I ended up using: LIBS += -L/usr/local/Cellar/mysql/5.1.54/lib/mysql/ -lmysqlclient Thanks for your help!
