1.) Download the source pachage
2.) run configure -host
3.) make
But i got lost in the process because i was not able to make out what will be the host , target, needed for teh configure script.
I need to basically be able to debug programs running on armv6 architecture board which runs linux kernel 2.6.21.5-cfs-v19. The gdb executable which i intend to obtain after compilation of the source,also needs to be able to run on above mentioned configuration.

* You create a first version with (for example) ruby script\generate scaffold product title:string description:text image_url:string
* This create (for example) a migration file called 20080910122415\_create\_products.rb
* You apply the migration with rake db:migrate
* Now, you add a field to the product table with ruby script\generate migration add\_price\_to\_product price:decimal
* This create a migration file called 20080910125745\_add\_price\_to\_product.rb
* If you try to run rake db:migrate, it will actually revert the first migration, not apply the next one! So your product table will get destroyed!
* But if you ran rake alone, it would have told you that one migration was pending
Pls note that applying rake db:migrate (once the table has been destroyed) will apply all migrations in order.
The only workaround I found is to specify the version of the new migration as in: rake db:migrate version=20080910125745
So I'm wondering: is this an expected new behavior?

I would rather push it so CSS, so for the few controls I have done in the past, I have simply stuck a string property which allows you so type in the string which in then slung in a "*style*" attribute when rendering. I know I could also use the "**CSSClass**" property and apply the "*class*" attribute.
I have not done much in the way of creating a "proper" **Style** property (in which you actually save the style object, and use the designer to specify its values). This to me seems like a lot of work, and TBH, I hate the Style editor UI and would much rather type in the CSS/class name to apply..
##What are your thoughts on this?

**The accepted answer will be the one that:**
* Offers the pro's and con's of the various approaches.
* Opinions are welcome, but a good answer should be constructive.

I know I should probably use mock objects but how exactly would I go about that in this case?

One thing that would make supporting each others code more helpful would be a LINTER that would check our code for common problems and assist with enforcing a shared code formatting style.
I of course want to be able to add my own rules and, after I prove their utility to myself, promote them to the rest of the team..
I don't mind doing the work that has to be done, but of course also want to leverage the work of other existing projects.
Does having the allowed language syntax in a yacc or bison format give me a leg up?
or should I just suck each language statement into a perl string, and use pattern matching to find the things I don't like?
(most syntax and compilation errors are easily caught by the commercial tools.. but we have some of our own extentions.)
