build products seem to go to the wrong branch
by Ben Coman 02 Jul '16

I just did my first vm build from git... $ git checkout -b firstbuild Cog $ cd image $ ./buildspurtrunkvmmakerimage.sh $ cd build.linux32x86/squeak.cog.spur/build $ ./mvm Which completes okay, but reports... Libraries have been installed in: /home/ben/Repos/OpenSmalltalk/vm/products/cogspurlinuxht/lib/squeak/5.0-201606221719-btc/condense-gitignore but condense-gitignore is not the current branch, but a previous branch I worked on where I didn't even do a build (I'm reasonably sure, but maybe I forget). $ git branch [snip] * firstbuild btc/condense-gitignore I poked around and found the message comes from ./platforms/unix/config/ltmain.sh but I don't see any git commands there to determine the branch, so it seems the branch must be passed to ltmain from somewhere else?? cheers -ben
