Use Ruby 1.9.3 on Cloud9 IDE

gistfile1.txt

**Cloud9 now has rvm, so you can switch easily (`rvm use X`), no need for this gist anymore**

# first thing to do is to get your VM's GUID
# do a 'pwd' in the console and grab the part after /var/lib/stickshift
# -> replace all GUID calls in this file :-)

create file: .gemrc

install: --no-rdoc --no-ri
update: --no-rdoc --no-ri
gemhome: /var/lib/stickshift/GUID/app-root/data/.gems
gempath: 
    - /var/lib/stickshift/GUID/app-root/data/gems/1.8

cp .gemrc ../

# install rvm
curl -L https://get.rvm.io | bash -s stable --ruby

# so this needs to be done every time apparently, add it to bashrc or something
# RUN IT IN TERMINAL! (Open via ALT+T)
source /var/lib/stickshift/GUID/app-root/data/.rvm/scripts/rvm
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile

rvm use 1.9.3

ruby --version
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]                                             

Ruby is now in ~/.rvm/rubies/ruby-1.9.3-p194/bin/ruby in case you want to run it that way


# add to ~/.bashrc
source $HOME/.rvm/scripts/rvm
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
rvm use 1.9.3

Trying to install libyaml fails with a message to the effect of Libtool library used but LIBTOOL is undefined. I would have copy & pasted it, but that doesn't seem to work from the terminal.

Apparently copy & paste works from chrome :D

src/Makefile.am:2: Libtool library used but `LIBTOOL' is undefined
src/Makefile.am:2:   The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
src/Makefile.am:2:   to `configure.ac' and run `aclocal' and `autoconf' again.
src/Makefile.am:2:   If `AC_PROG_LIBTOOL' is in `configure.ac', make sure
src/Makefile.am:2:   its definition is in aclocal's search path.
make: *** [Makefile.in] Error 1

Hi @bm5k, I don't think it's required, I don't have it installed and works fine for me. I'll see what is required to get it installed though.

@bm5k: That looks like a bug in the libyaml automake script. It's probably written for an older (or possibly newer) version of autotools than what the C9 VMs ship with.

@janjongboom for now, I am progressing without it.

@bnoordhuis I don't know enough about the environment C9 provides in its workspaces to know the answer to that.

@bm5k: Just tried it, seems to work for me. You may have to run autoreconf -ivf first.

Can all instances of /var/lib/stickshift/GUID/app-root/data/ be safely replaced with $HOME in the script above?

Yeah pretty sure.
