Problem

I want to run Subversion v1.85, client and server, on CentOS 5 (today's victim server is 5.10).

Solution

You can't do that. Well you can, but it is ugly.

You have several problems:

  • Subversion wants a newer version of sqlite than is shipped with CentOS-5.
  • Subversion depends on serf for http access.
  • Serf depends on newer versions of apr and apr-util than ship with CentOS-5.
  • apr and apr-util are intimately related to the apache you intend to use to run the server component.
  • oh and just to ensure you shave the requisite number of yaks, Serf requires a build system I've never heard of before.
So I had a bunch of choices, most of which boiled down to
  • throw CentOS-5 away (not viable for other reasons)
  • build a whole Apache for Subversion to use (something I would rather avoid if at all possible)
  • build two instances of Subversion: one for the installed CentOS-5 Apache, and one with more modern libraries
The last option is a hack, but I tried it and it worked for me.

Things I downloaded:

  • apr 1.5.0
  • apr-util 1.5.3
  • scons-local-2.3.0
  • serf-1.3.3
  • sqlite-autoconf-3080200
  • subversion-1.8.5
Everything else was satisfied with yum. (I have EPEL loaded but I think all other dependencies came from the Base or Update repositories.)

I'm installing things out-of-tree because I want all this junk usable from arbitrary systems on the network. In this case one component of all the prefix values is C5-32, for CentOS-5 32-bit, because I also have A) CentOS-6 and B) CentOS-5 64-bit systems around. This process was repeated for C5-64 (the client-side anyways) and it still worked.

So to repeat: if you do this you'll end up with two full builds of Subversion, one for Apache and one for the client. You can probably get rid of most of the stuff in the Apache install tree but frankly disk space is cheap these days.

Your overview:

  • build sqlite
  • build subversion the first time
  • build apr
  • build apr-util
  • build serf-1.3.3
  • build subersion the second time in a different location
  • mess with the httpd conf file
  • restart httpd

Server Pieces

Build sqlite

$ ./configure --prefix=/projects/common/C5-32/sqlite/3080200
$ make ; make install

Build Subversion The First Time

This is the build that the running apache from CentOS 5 is going to use.

# ./configure --prefix=/projects/common/C5-32/subversion/1.8.5-server --with-sqlite=/projects/common/C5-32/sqlite/3080200
# make ; make install

httpd conf changes:

I have this file as /etc/httpd/conf.d/subversion.conf

LoadModule dav_svn_module     /projects/common/C5-32/subversion/1.8.5-server/libexec/mod_dav_svn.so
LoadModule authz_svn_module   /projects/common/C5-32/subversion/1.8.5-server/libexec/mod_authz_svn.so
<Location /svn_dgm>
   DAV svn
   SVNPath /var/www/svn/svn_dgm
      AuthType Basic
      AuthName "Authorization Realm"
      AuthUserFile /etc/svn-auth
      Require valid-user
</Location>

Create /etc/svn-auth as usual; create yourself the repository at /var/www/svn/svn_dgm; and restart httpd.

Client Build

Build sqlite

As above, if you have not done so already. Otherwise, proceed.

Build apr

$ ./configure --prefix=/projects/common/C5-32/apr/1.5.0
$ make ; make install

Build apr-util

I installed this into the same tree as the apr. In hindsight this might not have been the brightest move I could have made. However it A) hasn't bitten me yet and B) how I did this, so there you are.

$ ./configure --prefix=/projects/common/C5-32/apr/1.5.0 --with-apr=/projects/common/C5-32/apr/1.5.0
$ make ; make install

Install scons

Yes, lets shave them yaks. Yet another build tool because autoconf just working is old and busted for some reason. This sequence is how I did it; if you want/need for scons for something else you might want to be more permanent about it.

$ mkdir ~/local
$ cd ~/local
$ tar xfz ~/Downloads/scons-local-2.3.0.tar.gz

Build and install serf

This is the library that handles the http access scheme for svn. It requires an updated apr/apr-util. If you try to build against the CentOS-5 versions, you get an error which some googling will eventually lead you to some snide comments about how "nobody should have any business running such old software versions".

First thing to do is to make scons.py reachable in the local directory, then build and install serf:

$ ln -s ~/build/local/scons.py scons.py
$ ./scons.py PREFIX=/projects/common/C5-32/serf/1.3.3 APR=/projects/common/C5-32/apr/1.5.0 APU=/projects/common/C5-32/apr/1.5.0
$ ./scons.py install

Build and install Subversion a second time

This build instance is the one that users will actually use. Note the different prefix value for installation.

$ ./configure --prefix=/projects/common/C5-32/subversion/1.8.5 --with-apr=/projects/common/C5-32/apr/1.5.0 --with-apr-util=/projects/common/C5-32/apr/1.5.0 --with-sqlite=/projects/common/C5-32/sqlite/3080200 --with-serf=/projects/common/C5-32/serf/1.3.3 --with-sasl
$ make ; make install

Client environment

In order to access the new svn client, each user must do this to their environment:

$ export LD_LIBRARY_PATH=/projects/common/C5-32/serf/1.3.3/lib/:$LD_LIBRARY_PATH
$ export PATH=/projects/common/C5-32/subversion/1.8.5/bin:$PATH

Now subversion is available:

$ svn --version
-bash: subversion: command not found
[dmackintosh@cvshost subversion-1.8.5]$ svn --version

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
