Hi Nicolas,<br>
<br>
yes it would be good to update Bochs. I looked at it a few years ago<br>
and it was quite done work. So I’ve avoided it until now. Looking at what<br>
you’re going below it may still be possible to build it. The conf.COG<br>
scripts to run are those in build.*/bochs*. So...<br>

On cygwin it does look like we have to update at least the configure<br>
scripts:<br>
$ cd build.win32x86/bochsx64/<br>
<br>

configure: error: cannot guess build type; you must specify one<br>
$<br>
<br>
So we should<br>
- add build directories in build.win64x64/{bochsx64,bochsx86,gdbarm32}<br>
& build.win32x86/gdbarm32<br>
- update the configure scripts only in processors/IA32/bochs<br>
- make sure the build procedure is documented<br>
<br>
I only develop the VM on macOS so I've not noticed that the cygwin build no<br>
longer works. I apologize.<br>

The problem is that the Bochs copy is super old. So we won't get support<br>
for compilation on uptodate machines...<br>
We cannot upgrade easily, since there are COG specific changes requiring to<br>
be replayed...<br>
grep -r COG processors\IA32.<br>
<br>
I also have doubts about the conf.COG files:<br>
is --disable-x86-64 really what we want?<br>
