Thanks for your help. I'm using the following command wine mysqld.exe -O lower_case_table_names=0 --lower_case_table_names=0 --innodb_data_file_path=ibdata1:100M --innodb_data_home_dir=Z:\\mysql-win-demo\\data\\ibdata --innodb_log_group_home_dir=Z:\\mysql-win-demo\\data\\ibdata\\log --innodb_mirrored_log_groups=1 --innodb_log_files_in_group=3 --innodb_log_file_size=5M --innodb_log_buffer_size=8M --innodb_flush_log_at_trx_commit=1 --innodb_buffer_pool_size=16M --innodb_additional_mem_pool_size=2M --innodb_file_io_threads=4 --innodb_lock_wait_timeout=50 --master-port=8808 --port 8808 --default-character-set=latin1 --basedir=Z:\\mysql-win-demo --datadir=Z:\\mysql-win-demo\\data --console --standalone --bind-address=127.0.0.1 with mysql-5.1.55-win32.zip. I haven't edited any configuration file. This works in a DOS shell but not with my Ubuntu....
