odbc32 is the MS ODBC driver manager. Under Linux you should use unixODBC 
instead.

When you install a prepackaged version of Simple Components on Debian or 
Fedora these come with the driver manager is preset to unixODBC.

Since you seem to use sources, you should select the corresponding project 
scenario variable "odbc" in the GPS as "unixODBC". Because the default is 
"ODBC32", which is for Windows.

BTW, the folder ./test_components contains 

   components-odbc-odbc_bindings_tests.gpr

project. It performs extensive tests of both the bindings and the 
capacities of the DBMS and its driver you want to access.

Do not forget to install unix odbc, a driver for your DBMS (e.g. for 
PostgreSQL) and configure it (e.g. set up a datasource etc).
