I want to simulate VM from a Spur64VMMaker.image Unfortunately, it gets really difficult to compile Bochs plugins these days...
WINDOWS (cygwin64):
$ cd processors/IA32/winbochs/ $ source ./conf.COG
checking build system type... ../bochs/config.guess: unable to guess system type
This script, last modified 2002-03-20, has failed to recognize the operating system you are using. It is advised that you download the most up to date version of the config scripts from
ftp://ftp.gnu.org/pub/gnu/config/If the version you run (../bochs/config.guess) is already up to date, please send the following data and any information you think might be pertinent to config-patches@gnu.org in order to provide the needed information to handle your system.
config.guess timestamp = 2002-03-20
uname -m = x86_64 uname -r = 3.0.7(0.338/5/3) uname -s = CYGWIN_NT-10.0 uname -v = 2019-04-30 18:08
/usr/bin/uname -p = unknown

LINUX (Ubuntu 18.04 thru WSL)

If you meant to cross compile, use `--host'. See `config.log' for more details. cp config.h bochsconfig.h cp: cannot stat 'config.h': No such file or directory and don't forget to run ../bochs/makeem
The problem is that the Bochs copy is super old. So we won't get support for compilation on uptodate machines... We cannot upgrade easily, since there are COG specific changes requiring to be replayed... `grep -r COG processors\IA32`.
I also have doubts about the `conf.COG` files: is `--disable-x86-64` really what we want? https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/e77147b63208fb40a9a17... https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/Cog/processors/IA32/m...
