You need to explicitly list all the 32 bit versions of all those 64 bit libraries it's trying to link in. Once you do that, it'll work. There have been notes here indicating that the resulting binary won't run on a 32 bit system because of the differences in library locations, but I haven't verified it. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.
