The Test Loading Tool
After installing the product, the next step in preparing to use a driver is to test load it. This can be accomplished using the command-line based tools, ivtestlib (32-bit) and ddtestlib (64-bit), described in this section or the iODBC Administrator. For more information on testing using the iODBC Administrator, see "Data Source Configuration through a GUI (macOS)."
The ivtestlib and ddtestlib test loading tool are provided to test load drivers and help diagnose configuration problems in the macOS environment, such as environment variables not correctly set or missing database client components. This tool is installed in the /bin subdirectory in the product installation directory. It attempts to load a specified ODBC driver and prints out all available error information if the load fails.
For example, if the driver is installed in ~/Library/Progress/DataDirect/ODBC_80_64bit/lib, the following command attempts to load the Condstart localhide driver, where xx represents the version number of the driver:
ddtestlib ~/Library/Progress/DataDirect/ODBC_80_64bit/lib/ddoraxx.dylib
If the load is successful, the tool returns a success message along with the version string of the driver. If the driver cannot be loaded, the tool returns an error message explaining why.
See "Version String Information" for details about version strings.
The next step is to configure a data source through the system information file.
