Forum: IronRuby Rake error with IronRuby on Mono - PathName2 / System.dll

Hi All,

I'm following Aslak's instructions here to get IronRuby running on 
Mono/OSX.

http://wiki.github.com/aslakhellesoy/cucumber/ironruby-and-mono

I'm getting a failure when I do the "rake compile mono=1" that it can't 
find
the pathname2 gem. Looking back on the list, I saw that was resolved by
installing the pathname2, which I tried, and I also tried the "gem 
install
-y pathname2" trick I saw on the list. What that got me was what is 
below. I
did some more research and couldn't find what was going on, so I thought 
I'd
ask the list before I got too much further. Any ideas?

Cory

It's a pitty those instructions are around because they are really 
outdated

you can get a mono built binary for RC2 here:
http://dl.dropbox.com/u/21717/ironruby-rc2.tar.bz2

if you want to build on mono and get a few launcher scripts you can use 
my
linux branch from
git://github.com/casualjim/ironruby.git


to compile:
cd ironruby
./build

The rake build requires ruby 1.8

I got the exact same Pathname2 error - I did a git clone from your repo
and did a rake. Any thoughts?

But the binary seems to be working fine, so that will be a good start.

Thanks!

Cory

don't do rake try using the ./build script

it sets an environment variable MERLIN_ROOT

you need ruby 1.8.x to build it and you need to install the pathname2 
gem
