a strange odbc_connect error message

Hello everyone, Using Joachim Steinhauser's installation rules in sqlanywhere group (thanks to Joachim), I have downloaded all of the following sources and Installed them on Redhat 6.2 Linux 1) Apache_1.3.12 2) Php 4.0.4 3) Sybase ASA 7.0.1 4) UnixODBC-1.8.13 I can start asademo, php_info works well, ODBC DSN tested with DataManager and odbctest (it is ok), Apache works, but just a single problem occurs: When I try to connect database with the command "odbc_connect("demo","dba","sql")", (demo is the nams of the system DSN) it gives the following error: "Warning: SQL error: [unixODBC][Driver Manager]Driver's SQLAllocHandle on SQL_HANDLE_HENV failed, SQL state IM004 in SQLConnect ..." Is it related with ODBC driver that I have selected in ODBCConfig??? I have added a new driver in ODBCConfig for ASA 7.0.1 with driver="opt/sybase/SYBSsa7/lib/libodbc7.so setup="opt/sybase/SYBSsa7/lib/libodbc7.so file usage=1 options. As I said before, it works in DataManager. Any help will be very very good. Thanks a lot to everyone that read this message Bye Alpay Alkan
