It’s been a while since I’ve triedthe Merb-on-Windows-from-scratch so I started from and found that it has gottens a lot easier since the last time I tried.
It’s now a two step process:
- Install the Ruby One-Click Installer
- Follow the instructions on at http://merbivore.com/index.html
But for those of you who want the blow-by-blow account…
- Download Ruby One-Click Installer[ruby186-26.exe]
- Install - select all defaults.
- Run “RubyGems Package Manager”
- (Start -> All Programs -> Ruby-186-26 -> RubyGems -> RubyGems Package Manager)
- this brings up a command window
- - Execute “gem install merb –include-dependencies”
- select “1. ParseTree 2.1.1 (i386-mswin32)”
- select “1. mongrel 1.1.5 (x86-mswin32-60)
- Wait for 10 minutes or so while the rdoc is installed…
- Execute: merb-gen app my_application
- Execute: cd my_application
- Execute: merb
- wait a few moments for it to start up…
- open your browser of choice to http://localhost:4000
Success!
I want to extend a major kudos to the folks working on Merb for improving the Merb-on-Windows story so significantly.

When trying to perform a migration (rake db:migrate) I hit the following error:
$ rake db:migrate
(in /home/Robert/ruby/merb_apps/blog)
svn: '.' is not a working copy
Connecting to database...
Thu, 20 Dec 2007 01:48:09 GMT: loading gem 'merb_activerecord' from config/dependencies.rb:16 ...
rake aborted!
No such file or directory - /tmp/mysql.sock
(See full trace by running task with --trace)
After a few minutes of googling and some trial/error I discovered that changing “localhost” in the database.yml file to the loop back address 127.0.0.1 resolved the issue. Apparently when you specify an IP address the :socket: value is not needed. Since the default merb database.yml content includes the line:
:socket: /tmp/mysql.sock
This is something that other Windows users may need to modify.
This is my updated config/database.yml file:
:development: &defaults
:adapter: mysql
:database: blog_development
:username: root
:password:
:host: 127.0.0.1
:test:
<<: *defaults
:database: blog_test
:production:

:database: blog_production

When attempting to create a new controller in merb on a cygwin installation I hit the following error:
$ ./script/generate controller post
svn: '.' is not a working copy
/home/Robert is insecure (40777). It may not be group or world writable. Exiting.
Ignore the svn issue for now - I don’t know why script/generate tries to interact with svn but the problem is the home directory permissions.
I believe this is an issue with RubyInline requiring more secure permissions than Ruby itself requires.
To resolve the issue I executed:
$chmod 750 /home/Robert
After that generating the controller worked as expected.

I’m getting ready to dive deeper into merb and wanted to install merb_activerecord. Unfortunately when I tried this I hit the following error:
$ gem install merb_activerecord
Updating metadata for 32 gems from http://gems.rubyforge.org
................................
complete
Building native extensions. This could take a while...
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
OpenURI::HTTPError: 404 Not Found reading http://gems.rubyforge.org/gems/activesupport-2.0.2-.gem
So I tried “gem update activesupport” and hit the same error.
I went out to the ActiveSupport RubyForge page found that 2.0.2 was released today. So I went to http://gems.rubyforge.org (which redirected to http://gems.rubyforge.vm.bytemark.co.uk/gems) and the latest version available in 2.0.1. So I assume this is just an issue of needing to wait for data to shuffle around.
But I’m impatient.
So I downloaded the gem file from http://rubyforge.org/frs/download.php/29344/activesupport-2.0.2.gem and installed as:
$ gem install activesupport-2.0.2.gem
Successfully installed activesupport-2.0.2
1 gem installed
Installing ri documentation for activesupport-2.0.2...
Installing RDoc documentation for activesupport-2.0.2...
When that was done I was able to successfully install merb_activerecord as follows:
$ gem install merb_activerecord
Successfully installed merb_activerecord-0.4.3
1 gem installed
Installing ri documentation for merb_activerecord-0.4.3...
Installing RDoc documentation for merb_activerecord-0.4.3...
The lessons here are that just-released gems might not be available via “gem install” even though they are a listed dependency of other gems and that manually downloading and installing gems is trivial.

When getting merb working on Windows I provided a patch to the merb folks that resolved a Rakefile compat problem (sudo was being used even when on Windows - where it does not exist).
I’m trying various configurations on Windows and found that in cygwin the platform name does not include “win32″ so the filter no longer worked (and cygwin does not include sudo).
I filed a ticket http://merb.devjavu.com/ticket/361 and attached the patch. It’s very simple:
$ cat cygwin.diffIndex: Rakefile
===================================================================
--- Rakefile (revision 1087)

CLEAN.include ['**/.*.sw?', '*.gem', '.config']
-windows = (PLATFORM =~ /win32/)
+windows = (PLATFORM =~ /win32|cygwin/)
SUDO = windows ? “” : “sudo”
And then it all goes well …

UPDATE: Installing Merb on Windows is now a lot easier! Check it out here.
This post outlines the exact steps I took to get merb working on Windows (to be specific - Vista Home Premium)
- Install InstantRails (I have no reason to believe this won’t work with the one-click installer).
- Start InstantRails and open a Ruby Console window (the steps following take place in that window)
- Execute “gem install hoe” (RubyInline depends on hoe)
- Download http://web.mit.edu/~agp/www/parsetree-win32/ParseTree-2.0.2-mswin32.gem
- Download http://web.mit.edu/~agp/www/parsetree-win32/RubyInline-3.6.4.gem
- Execute “gem install RubyInline-3.6.4.gem”
- Execute “gem install ParseTree-2.0.2.mswin32.gem”
- Execute “gem install ruby2ruby”
- Execute “gem install json” (choose json 1.1.1 (mswin32))
- Execute “gem install merb -y”
- Execute “merb myapp”
- Execute “cd myapp”
- Execute “set INLINEDIR=c:/temp” (the slash direction matters!)
- Execute “merb”
- Browse to http://localhost:4000 and …
So a big thanks to Ezra for providing the pointers I needed.
Hopefully these steps will prove useful for others.

After my last merb post Ezra left a comment with some concrete suggestions to move forward with getting merb working on Windows. My next post will cover that exact topic but I wanted to create a post to captute the stack traces of the errors I hit when trying to get merb running.
The first was a dependency issue. Merb requires json but I did not have it installed. I think the merb gem should have noted this dependency but honestly I don’t understand gems enough to know for sure. The output of the merb command and call stack is:
C:\InstantRails\ruby\merb>merb
Merb started with these options:

I fixed this by installing json 1.1.1 (mswin32).

With the dependencies resolved I re-ran merb but hit another error message. I’ll give you the output and call stack first and see if you see the problem:

See it yet?
Require failed to find the file C:/InstantRails/ruby/merb/config/merb_init.rb. But why?
Because I’m an idiot :). I ran the merb command from the wrong directory. I needed to move to the application directory at which point I re-ran merb and …
Wait for the next post!

[Update: Merb is now working on Windows]
Previously I ran into this error when trying to get merb running on Windows:

It turns out that merb depends on RubyInline which is the Ruby way to generate C code via Ruby. Why does it require C code generation? Honestly I’m not interested enough to continue digging. I’m not installing gcc on this box. A quick glance into inline.rb shows that this is a gcc-specific generator and I’m not inclined to spend a day writing the VC interface just to get another step further with merb.
Perhaps I’ll try merb out on my desktop sometime - I dual boot it to Ubuntu - but the point of having it on the laptop was so that I could veg out in bed after the kids were asleep and the wife and I are winding down (and I’m not putting Ubuntu on this machine - Vista is very stable and everything is working how I want it - I’m not going to tempt fate by changing partitions and adding grub). I know I could remote in to the desktop via any number of protocols but this was just to see what I thought of merb. I think at this point I’ve figure that out.
Merb looks interesting but has taken, so far, a very unix-centric development turn. Rails is far more platform neutral and is therefore more compelling to me.
I’ll continue to keep an eye on merb, though. It looks promising.
