[Vm-dev] attempting to build BochsX64Plugin on 32-bit Ubuntu

Sun Oct 25 19:05:39 UTC 2015

Eliot, thank you for that orientation. I looked at your mac but had to 
go one more step. I realized I probably couldn't build both 
BochsIA32Plugin and BochsX64Plugin at the same time while sharing the 
processors/IA32 support code - it is compiled separately for IA32 and 
X64. So I added a processors/X64 directory, with a seaparate copy of 
Bochs for 64-bit emulation, built the libs with your conf.COG from mac, 
and built both Bochs plugins. I am attaching the link to BochsX64Plugin 
for 32-bit linux: 
https://www.dropbox.com/s/g73feosuzlx45le/BochsX64Plugin.11-25-2015.tgz?dl=0

Best,
Robert

... ^^
