This may be somewhat off topic (if so, please point me to the right list) but it is most certainly an AMD64 issue. Icarus Verilog (my Verilog simulator) is capable of dynamically loading third party PLI objects precompiled to be loaded by Cadence simulators (standard API) on Linux/i386 systems. I presume that a 32bit program running on an AMD64 can load these 32bit shared objects no problem. What I'm looking for is how to come up with a thunk or interface where my *64bit* program can load 32bit shared objects. This seems like an absurdity, but if there are hints or suggestions on how I might make it work, I'm listening. -- Steve Williams "The woods are lovely, dark and deep. steve at icarus.com But I have promises to keep, http://www.icarus.com and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep."
