Adding git-svn support from source

2009 January 25

Having workstations where you don’t have root access either means contacting support for installation or building your own software from source to get the latest version.

I started using git for code produced in my work. The build was successful with a simple “./configure; make ; make install” series of steps except for supporting access to subversion repositories. It was looking for the perl module SVN::Core to be able to function successfully. Googling about it will land you to the Alien::SVN CPAN module page. Its dependencies can be installed with the standard “install Module::Name” invocation in the CPAN shell. But the main package does not properly install in this environment. It is probably because of the tarball not containing the standard Makefile.PL. It has Build.PL instead. This script generates the Build that compiles the subversion library and its bindings. Then it generates a Makefile from Makefile.PL in the _src/subversion/subversion/bindings/swig/perl/native _directory. Below is the output of the script:

[sourcecode light=“true”] [Alien-SVN-]$ ./Build Running make Running make swig-pl-lib make: Nothing to be done for `swig-pl-lib’. Running /usr/bin/perl Makefile.PL INSTALLDIRS=site Writing Makefile for SVN::_Core Writing Makefile.client for SVN::_Client Writing for SVN::_Delta Writing Makefile.fs for SVN::_Fs Writing Makefile.ra for SVN::_Ra Writing Makefile.repos for SVN::_Repos Writing Makefile.wc for SVN::_Wc Running make gcc -c -I$HOME/local/include/apr-0 …

The command /usr/bin/perl Makefile.PL INSTALLDIRS=site generates a build environment to install in_ /usr_. This is not favorable for installation in userspace since you do not have permission to write on that directory. So this command will be rerun /usr/bin/perl Makefile.PL PREFIX=\(USERDIR_, where _\)USERDIR is the destination directory you want to.

Now you can successfully clone subversion repositories!
