Since I am using SunStudio 11 should I change flags sun OPTIONS <architecture>/<address-model>32 : -m32 ; flags sun OPTIONS <architecture>/<address-model>64 : -m64 ; to flags sun OPTIONS <address-model>32 : -xarch=generic32 ; flags sun OPTIONS <address-model>64 : -xarch=generic64 ; Thanks, Ford Sleeman NOTE: The information contained in this message may be privileged and confidential and protected from disclosure.
