end

When working with gems (as in writing them) use this in your gemspec for specifying a specific sqlite3 based on the platform:

gem.add_dependency "sqlite3" if RUBY_PLATFORM == "ruby"

gem.add_dependency "jdbc-sqlite3" if RUBY_PLATFORM == "java"
#gem.add_dependency "activerecord-jdbcsqlite3-adapter" if RUBY_PLATFORM == "java"
gem.add_dependency "jruby-openssl" if RUBY_PLATFORM == "java"

In these instances, I am adapting to change for use with JRuby. Modify as you need for the Windows platform.

Try something like:

if RUBY_PLATFORM =~ /(win|ming)/
...
else
...
    end

Hi all,

We use ruby as part of our development team tools for Windows and Mac machines. This is maintained internally in an SVN repository where the platform-specific files are interleaved, i.e. the bin/ directory contains both a Windows ruby.exe and a Mac ruby executable. This repository is packaged into installers so we can deploy to our dev team ensuring that everyone has the correct ruby version and gems.

New gems are installed on an administrator’s machine and SVN added to the gems folder (and the corresponding gemspec is added to the specifications folder). Most of these are platform agnostic but we have a few that are Windows-only, e.g. qtbindings.

This was working fine until trying to get sqlite3 running on both PC and Mac. The PC version was installed first (gems/sqlite3-1.3.6-x86-mingw32) and this worked fine. The mingw32 version is PC only so I installed sqlite3 on an OSX machine which added the new gem to gems\sqlite3-1.3.6.

This new gem conflicts with the PC version, e.g. attempting to require via IRB on the Mac:

irb(main):001:0> require 'sqlite3'
LoadError: cannot load such file -- sqlite3/sqlite3_native
                from /Users/aallmont/nm/buildtools/ruby/1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
                from /Users/aallmont/nm/buildtools/ruby/1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

This error goes away if I remove the gems/sqlite3-1.3.6-x86-mingw32 folder on the Mac. There is a similar error on the PC which goes away if I remove the gems/sqlite3-1.3.6-x86 folder, i.e. they are mutually exclusive.

I would like to only load gems/sqlite3-1.3.6-x86 when running on the Mac and only load gems/sqlite3-1.3.6-x86-mingw32 when running on the PC. Is this possible?

Many thanks,
Alex
