The way to get rid of the " Revision: VM: $URL$ $Date$ Date: $Rev$

Plugins: $Rev$" nonsense in the version report is to make sure to run

scripts/updateSCCSVersions

Even though I know this, I usually forget for the first run on a new machine. Is there some reason this can't be run as part of make?

exactly once before you build. From then on the checkin script scrips/gitci makes sure that this is up-to-date. You'll get something more useful

such as

VM: 201705161708 eliot@Sisyphus:oscogvm $ Date: Tue May 16 10:08:12 2017

-0700 $

which allows me to identify this VM as one I build myself on my Mac Mini

Sisyphus in directory oscogvm, which contrasts with the official binary VMs.

Ideally the script would be run automatically after the repository was

cloned. Do git mavens know if a post-clone hook is available to make this happen? If so, can someone make it so?

The blocker to this is that clone does not install the hooks. Maybe the hooks be installed by make? Of course, everyone should look at the README, but unfortunate human nature its a bit TL;DR. The alternative could be a SETUP or QUICKSTART file in the root directory, to make it more obvious it should be run.

btw, could someone actually explain how this works... git config --local include.path ../.gitconfig git stash -q || true echo "//" >> platforms/Cross/vm/sqSCCSVersion.h echo "//" >> platforms/Cross/plugins/sqPluginsSCCSVersion.h git checkout HEAD -- platforms/Cross/vm/sqSCCSVersion.h git checkout HEAD -- platforms/Cross/plugins/sqPluginsSCCSVersion.h git stash pop -q || true I can't grok its magic. Hopefully that highlights why its the same script for each of post-checkout, post-commit & post-merge

Also, at https://github.com/OpenSmalltalk/opensmalltalk-vm if you click on the green <Clone or download> button and then on "Download ZIP" I found (from memory) that running mvm seems to successfully build a VM on a Mac (but I didn't validate the version info). However on Linux the build fails in a way that seems similar to when updateSCCSVersions hasn't been run. But that script depends on git, whereas I presume it would be good to be able to build from the ZIP download without git - particularly for Linux distributions that source compile their packages. Indeed, I think Alistair bumped into this packing the VM for nixos.

So I notice that this file... https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/Cog/platforms/Cross/v... is dated 16 Dec 2016. Why isn't this file kept synchronised to identify the checked in build? So that compiling from the ZIP download would have correct version info?
