(on a Linux system)
I have a large set of nested subdirectories on a filesystem. I would like to prune all directory paths that contain no files at all.
In other words I would like to delete every directory where there are no files in that directory or in any subdirectory of that directory recursively.
I've written some software that uses Perl code running inside Apache (using mod_perl) to work with (amongst other things) subversion (using the mod_dav_svn module).
I'm currently writing some how-to docs on how to get this set up and running on various OSs and I've run into problems on Solaris.
It seems that my option is to build either mod_perl or subversion from source, which is something I was really hoping to avoid as I'm trying to make the install instructions as non-technical as possible.
So, is there a binary package available that lets me get mod_perl and mod_dav_svn running in the same Apache on Solaris 10 that I've missed?
Failing that, if there's anyone who has had to do this before, would they like to comment on which of building svn or building mod_perl is going to be the smallest headache.
I'm currently in the process of writing setup instructions for some software I've written that is implemented as a set of Perl modules. Having done this for various flavours of Linux, I'm now doing the same for Solaris/OpenSolaris (v10 only).
Part of the setup process is to make sure that dependent Perl modules are installed. This has been pretty easy on Linux as the Perl modules I require tend to be within the distro's packaging system (eg yum install perl-Cache-Cache).
This is not the case on Solaris so I'm working on setup instructions that use the CPAN module to fetch dependent modules (eg perl -MCPAN -e 'install Cache::Cache'). This works ok but there are known problems with modules that require things to be built with a C compiler.
The problem is that the C Makefile generated assumes you're using Sun's compiler and uses command-line options not understood by gcc, which you may be using instead. Consulting teh Internetz has thrown up a number of solutions to this:
perlgcc wrapper scriptAll of these work. My question to those more familiar with Solaris than me is: Is one of these the 'best' or 'most commonly used' method?
For certain reasons I have to keep a slightly older version of a particular RPM installed on my box (Fedora 11). The problem is that every time I do a package update yum (or one of its GUI equivalents) wants to update this RPM to the latest version, which is annoying - especially when I update it by mistake.
Is there a way to 'pin' this version so that yum knows to never try and update it?
