For example, if git was installed to /opt/git with make prefix=/opt/git install you can install symbolic links in /usr/local/bin with make symlinkprefix=/usr/local prefix=/opt/git \ install-symlinks This makes it reasonably easy to remove such a package, by doing rm -rf /opt/git and then removing stale links with find /usr/local -xtype l -print0|xargs -0 rm (be sure to first see whether you indeed get only stale links listed). This works by copying the directory hierarchy of $prefix to $symlinkprefix (not copying or descending to any directories of the name git* matched case-insensitively), then linking all the rest.

Of course, this was because I added the wrong Makefile. I am not sure how git could be more helpful here. Just wanted to report it. Maybe it could have noticed that my "amendment" was empty? On the other hand, I might have wanted to amend the commit message.

Sometime about now you'll need to define $(FIND) or even $(GNUFIND) for find. There are proprietary systems where find is not available or does not do what you want it to. There is often a gfind installed somewhere on these systems. ``` ## David Kastrup, 2007-07-18 14:06 Subject: Re: [PATCH] Makefile: create an install-symlinks target Message-ID: <861wf5iz6o.fsf@lola.quinscape.zz> URL: https://gitlist.dev/e/861wf5iz6o.fsf%40lola.quinscape.zz In-Reply-To: <81b0412b0707180608j7c22631ak87f3ddd6481bccf2@mail.gmail.com> ``` "Alex Riesen" writes: > On 7/18/07, David Kastrup wrote: >> + @: $(MAKE) && cd '$(prefix_SQ)' && find . -mindepth 1 ... > > Sometime about now you'll need to define $(FIND) or even $(GNUFIND) > for find.

I think that the install-symlinks target is rather more specialized than the tags and TAGS targets, yet those use just "find". I think I'll be able to throw out the -mindepth, however. It was necessary in a version that used find $(prefix), since /opt/git matched -type d -name git* but with find . this should not be relevant. I'll amend that patch and prepare a separate one that uses $(FIND) everywhere. -- David Kastrup ``` ## Peter Baumann, 2007-07-18 14:33 Subject: Re: [PATCH] Makefile: create an install-symlinks target Message-ID: <20070718143329.GD4815@xp.machine.xx> URL: https://gitlist.dev/e/20070718143329.GD4815%40xp.machine.xx In-Reply-To: ``` On Wed, Jul 18, 2007 at 01:48:21PM +0100, Johannes Schindelin wrote: > Hi, > > On Wed, 18 Jul 2007, David Kastrup wrote: > > > Use this, for example, to do > > rm -rf /opt/git > > make prefix=/opt/git install > > make symlinkprefix=/usr/local prefix=/opt/git install-symlinks > > You mean > > This target allows you to have git installed in one location, > and have symbolic links to all of the programs installed in > another location.

Somehow I find so many symbolic links ugly. > Seeing this excellent explantion from Dscho, this sound exactly like a perfect use case for xstow [1]. It allows you to install your application into e.g. /usr/local/stow/git and by running 'xstow git' in /usr/local/stow it would create all the necessary links in /usr/local/{bin,share,doc} or any other place you want. -Peter [1]: http://xstow.sourceforge.net/ ``` ## David Kastrup, 2007-07-18 14:45 Subject: [PATCH 2/2] Makefile: use $(FIND) instead of find Message-ID: URL: https://gitlist.dev/e/e59329b96603b8ed323b57179608bb7df9b57322.1184770193.git.dak%40gnu.org In-Reply-To: <6e14af24a3aa8af7e21e0a3f92c83c82e147202a.1184770193.git.dak@gnu.org> ``` Some people might prefer to be able to specify the find utility to use, in particular for the more complicated usage in the install-symlinks target.
