<br> <br>It’s those last two parts that imply something is going a bit off-track here. <br> <br>Now don’t forget I’m a fan of VMMaker, after all I invented it 14 years ago (actually so far as I can tell pretty much *exactly* ) but the convenience of being able to do an svn co, hit the OS-appropriate buttons and autoconfigure/build is considerable. Yes, I suppose one could have multiple svn branches for the (many, many) different versions of *nix but making use of the already existing CMake capability strikes me as more sensible. </div>
</blockquote><br><br><div>Existing functionality is unchanged. </div><div>There is only 1 SVN branch. </div><div>VMaker is unchanged</div><div>My additions are non-intrusive.<br></div><div><br></div><div>Regarding existing CMake capability, I am leveraging what the pharo team has already done. It appears Ian's work is hand coded CMakeLists.txt in trunk/platforms/unix and a configure script that generates the plugin CMake files. </div>
<div><br></div><div>Regarding your ability to just svn co and run cmake, I agree that will be nice and it can be done. However until the tool is mature we need something that will work with what we have without getting in the way. I believe this approach will accomplish that.</div>
