When linking the ODBC-ODBC bridge with Perl DBD::ODBC, you may get the following error:
/usr/local/easysoft/oob/client/include/sql.h:46, from /usr/local/easysoft/oob/client/include/sqlext.h:46, from dbdodbc.h:9, from ODBC.h:9, from ODBC.xs:1: /usr/local/easysoft/oob/client/include/sqltypes.h:14: wchar.h: No such file or directory
To rectify this problem, you need to comment out any references to wchar.h in /usr/local/easysoft/oob/client/include/sqlext.h.
