Configuration examples are given in this introduction section
Some functional aspects of Libgda can be configured using environment variables which are listed here:
GDA_CONNECTION_EVENTS_SHOW: if set, then lists the type of events which must be displayed on STDOUT (event types are NOTICE, COMMAND, WARNING, ERROR, the variable can contain a list of types separated by colons, commas or spaces)
GDA_PROVIDERS_ROOT_DIR: if set, must point to the directory where the providers files are (providers files are shared libraries)
LIBGDA_NO_THREADS: if set, then multi threading will be disabled (see the section about multi threading for more information about Libgda threads' support).
GDA_SHOW_PROVIDER_LOADING_ERROR: if set, then in case a provider fails to be loaded (usually because it requires a library which can't be found) Libgda will display a warning message. This variable is useful to debug the absence of a provider at runtime
GDA_DATA_MODEL_DUMP_TITLE: if set, then gda_data_model_dump() will also output the name of the data model as its first line
GDA_DATA_MODEL_DUMP_ROW_NUMBERS: if set, then gda_data_model_dump() will prepend a column containing row numbers
GDA_DATA_MODEL_NULL_AS_EMPTY: if set, then gda_data_model_dump() will show an empty ("") string for NULL values, instead of the "NULL" string
GDA_DATA_MODEL_DUMP_ATTRIBUTES: if set, then gda_data_model_dump() will also include a description of the data model's attributes
