Looks like some kind of link or something is broken when you try to GIT gnuradio. The build fails as volk will not build, and the volk sub- directory is empty. I did successfully GIT volk directly and clone it to it’s sub-directory in gnuradio, and the build then went fine. Just throwing that out there so someone can try to fix it or get it fixed.

This happened on Sunday. The --recursive flag could have been added at any point in anticipation of it. ---

Actually now I see it would probably be: git pull --recurse-submodules=on git submodule update – View this message in context: [http://gnuradio.4.n7.nabble.com/Empty-volk-directory-when-I-git-gnuradio-tp53073p53155.html](http://gnuradio.4.n7.nabble.com/Empty-volk-directory-when-I-git-gnuradio-tp53073p53155.html) Sent from the GnuRadio mailing list archive at [Nabble.com](http://Nabble.com). ---

When I clone from the gnuradio repository: _git clone_ --recursive [http://git](http://git)._gnuradio_.org/git/_gnuradio_.git The clone succeeds. It is on the master branch. I can checkout next, and switch back and forth between next and master. However when I attempt to checkout maint, git says the checkout is aborted because the untracked working tree (everything in volk) would be overwritten by the maint checkout. $ git checkout maint error: The following untracked working tree files would be overwritten by checkout: volk/CMakeLists.txt volk/apps/CMakeLists.txt … many line of volk/ contents … Aborting Any advice on how to get to the maint version? – Tom, N5EG ---

For feature branches, you’ll do this and then rebase off master to prevent this happening again. For maint, if you need it, best to keep a separate directory just for that branch. This is temporary. The planned release of 3.7.7 is next Monday. When that happens, master becomes maint, so the current maint issue will go away. Tom ---

Can you you add the --recursive in the README? I assume a standard “git pull” will be sufficient in the future or do we also need to do a “git submodule update”?

Thanks, Tom. It works. After checking out maint, I can checkout master then, git submodule init volk and now all 3 branches (next, master, maint) checkout correctly. My issue was being unfamiliar with git submodules. I’ll wait for 3.7.7 before further testing - so many new cool features to play with! – Tom, N5EG
