</div></div>I actually have interest but I am currently reluctant,<br>
for time-capturing reasons in my personal and work life.<br>
<br>
However, Here is what I would do:<br>
<br>
• Start from Ians CMake work, and try to generalize it for the<br>
non-Linux platforms<br>
• Windows would be kind-of straight-forward,<br>
• For OS X, I would really want to have the Cocoa-based VM stuff<br>
(aka Squeak VM 5.4.7.x) integrated and proper Xcode files<br>
generated, especially to be able to have iOS VMs built automatically.<br>
Here, some information from John McIntosh would be helpfull, especially<br>
a simple walk-through.<br>
I have some experience with that[1]<br>
<br>
<br>
Despite all admiration I have for the way the PharoVM is built, there is one<br>
thing that bothers me:<br>
• You first somehow generate the VM sources (which is fine, and the automated way is amazing)<br>
• THEN, the a Script generates CMake-Files<br>
• CMake then generates Makefiles<br>
• and then finally a vm is compiled.<br>
This is one generating step too much, for my taste.<br>
Personally, I'd prefer CMake to just pick up the C-files generated by VMMaker,<br>
so that adding a new platform does not need to change the VMMaker…</blockquote><div><br></div><div>The main big issue with 'platform-neutral' static source files, that they tend to<br></div><div>grow with tons of #ifdef-s over time, reducing readability and creating a mess.<br>
<br></div><div>My point is that one or another way you have to deal with platform differences,<br></div><div>and the way how i prefer to do it is using smalltalk code,<br></div><div>but not .m4 files, or .cmake files, or writing a medium novel long configuration files<br>
</div><div>using strange (better to say weird) scripting DSL.<br></div><div>I can express all build process logic in smalltalk, which does not lessens the amount<br>of work to deal with all platform nuances and dependencies etc, but at least it allows me to organize and shape it<br>
into some manageable form, which is easy to change & learn.<br></div><div> <br></div><div> And another difference is, that i prefer working with browser & classes than<br>with dozens of directories and files lying here and there.<br>

But if the community is positive to just move to the Pharo way of<br>
building VMs, I'd be fine with that, since that would unify a lot<br>
of infrastructure :)<br>
