Merb on Windows: environment variables required.

Posted in Programming, Ruby, merb at 1:56 pm by Robert Horvick

[Update: Merb is now working on Windows]  

After getting merb installed I created a project using “merb myapp” - this worked fine.  Next I tried just running “merb” to see where I was at.

Merb started with these options:---:merb_root: C:/InstantRails/projects/merb_1/myapp 

:reloader_time: 0.5
:cache_templates: false
:use_mutex: true
:session_id_cookie_only: true
:session_secret_key: C:/INSTANTRAILS/PROJECTS/MERB_1/MYAPP5259
:host: 0.0.0.0 

:query_string_whitelist: []
:reloader: true
:exception_details: true
:environment: development
:port: “4000″
Define INLINEDIR or HOME in your environment and try again

The error “Define INLINEDIR or HOME in your environment and try again” was not expected but I’m game.

I looked around for a place to define environment variables (since “:environment: development” seemed to hint that there would be one).

So I tried the obvious directory listing:

C:\InstantRails\projects\merb_1\myapp>dir development.rb /s 

 Volume in drive C has no label. 

 Volume Serial Number is 2256-DBBA 

Directory of C:\InstantRails\projects\merb_1\myapp\config\environments 

11/11/2007  12:48 AM                44 development.rb 

               1 File(s)             44 bytes 

I opened it and changed it’s contents to:

puts "Loaded DEVELOPMENT Environment..." 

ENV['INLINEDIR'] = “C:/Users/Robert/AppData/Local/Temp”

But the error persisted.  So I just set INLINEDIR in the environment.

Further … but now a new error:

Is it just me or does that look like it’s trying to run a C compiler?

Investigating now…

Installing Merb on Windows required Rakefile tweaks for sudo and chmod

Posted in Programming, Ruby, merb at 12:32 am by Robert Horvick

[Update: Merb is now working on Windows and the errors described in this post have been fixed in the latest svn trunk]  

Following the merb installation stepson my Vista laptop I discovered that the “rake install” was failing because the Rakefile contained explicit calls to sudo (and chmod).

When executing “rake install” the result was:

 C:\InstantRails\merb>rake install
(in C:/InstantRails/merb)
rake package
(in C:/InstantRails/merb)
  Successfully built RubyGem
  Name: merb

rake aborted!
Command failed with status (0): [sudo gem install pkg/merb-0.4.1 --no-rdoc ...]
C:/InstantRails/merb/rakefile:76
(See full trace by running task with –trace) 

 I modified the Rakefile to not use sudo on win32 (replacing it with “” instead) and to only execute chmod when not win32.  The patch is:

 end

I haven’t really thought about what the consequences of this change are but I did file a bug at the merb Trac in the event they want to fix platform blockers at this point in the dev cycle.
