Unresolved symbols in Informix 64 bit

Hi All, We are doing a migration of Informix 4gl application from 32 bit to 64 bit version. During compilation time we did not find any warnings or errors for the below mentioned symbols. But during run-time we find the below messages displayed. When we compile the SAME source with 32 bit informix compiler neither of them gets displayed. All these variables are declared as "extern" in the application. Are we missing something. If so please let us know ASAP. Thanks in advance. /usr/lib/pa20_64/dld.sl: Unsatisfied data symbol 'GB' in load module '/scl3/appl/sis/ipi/lib/libscs.sl' /usr/lib/pa20_64/dld.sl: Unsatisfied data symbol 'eflastkey' in load module '/scl3/appl/sis/ipi/lib/libscs.sl' /usr/lib/pa20_64/dld.sl: Unsatisfied data symbol 'topwin' in load module '/scl3/appl/sis/ipi/lib/libscs.sl' /usr/lib/pa20_64/dld.sl: Unsatisfied data symbol '_Wscreen' in load module '/scl3/appl/sis/ipi/lib/libscs.sl' /usr/lib/pa20_64/dld.sl: Unsatisfied data symbol 'curscr' in load module '/scl3/appl/sis/ipi/lib/libscs.sl' Regards, Vijay Kumar sending to informix-list
