You can run mysqld directly from the source directory (without doing make install).

Copy the following to your '~/.my.cnf' file.

There are two lines you have to edit: 'data=' and 'language='. Be sure to change them to match your environment.

# Example mysql config file.
# You can copy this to one of:
# /etc/my.cnf to set global options,
# /mysql-data-dir/my.cnf to get server specific options or
# ~/my.cnf for user specific options.
# 
# One can use all long options that the program supports.
# Run the program with --help to get a list of available options

# This will be passed to all mysql clients
[client]
#password=my_password
#port=3306
#socket=/tmp/mysql.sock

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

# The MySQL server
[mysqld]
#port=3306
#socket=/tmp/mysql.sock
skip-locking
temp-pool
set-variable  = key_buffer=16M
set-variable  = thread_cache=4
loose-innodb_data_file_path = ibdata1:1000M
loose-mutex-deadlock-detector
gdb

######### Fix the two following paths

# Where you want to have your database
data=/path/to/data/dir

# Where you have your mysql/MariaDB source + sql/share/english
language=/path/to/src/dir/sql/share/english

[mysqldump]
quick
set-variable = max_allowed_packet=16M

[mysql]
no-auto-rehash

[myisamchk]
set-variable= key_buffer=128M

With the above file in place, go to your MariaDB source directory and execute:

./scripts/mysql_install_db --srcdir=$PWD --datadir=/path/to/data/dir

Above '$PWD' is the environment variable that points to your current directory.

Now you can start mysqld in the debugger:

cd sql
ddd mysqld &

Or start mysqld on its own:

cd sql
./mysqld &

After starting up mysqld using one of the above methods (with the debugger or without), launch the client (as root if you don't have any users setup yet).

../client/mysql

Using a storage engine plugin

The simplest case is to compile the storage engine into MariadB:

configure --with-plugin-<plugin_name>

Another option is to point mysqld to the storage engine directory:

mysqld --plugin-dir=source-dir-path/storage/connect/.libs
