ruby-1.9.3-p0 ruby-debug and rvm

#Need the latest version so it knows where to get ruby-1.9.3
rvm get head

curl -O https://github.com/ruby/ruby/pull/56.diff

rvm install ruby-1.9.3-p0 --patch 56.diff

cd ~/.rvm/src/ruby-1.9.3-p0

# Need to recompile because rvm doesn't force autoconf?
autoconf -f && ./configure --prefix="$HOME/.rvm/rubies/ruby-1.9.3-p0" && make -j3 && make install

Since rvm 1.9.2, no need to autoconf manually. See the below Running autoreconf.

And even don't have to install libyaml manually as mentioned at Install Ruby 1.9.3 with Libyaml

Make sure you've have rvm at least 1.9.2 running rvm get head

For me I still needed to run autoreconf because when I checked for the symbol needed it wasn't there.

Would you try the following:
$ nm ~/.rvm/rubies/ruby-1.9.3-p0/bin/ruby | grep current_thread
if it returns something like 00000001002249d0 D _ruby_current_thread then maybe I just did it wrong...

Another way to check is to simply try to fire up the debugger.
$ ruby -v -r rubygems -r ruby-debug -e 'Debugger.start and puts Debugger.current_context'

If it works for you let me know, I'll change it up so it's not an ugly two step process.

Nop, the first command prints nothing and the second errors out:

So is it not installed properly?
Why the rvm installation logs that Running autoreconf? or is it mean something else?

Yea it's not installed properly, ruby-debug is bombing looking for symbols in the binary.

I ran into the same thing the first time I wrote the gist. I did a quick look through the rvm source and there is an autoconf function defined
scripts/functions/pkg, but it's not used or is called implicitly somewhere. Maybe it's not doing the -f (force) flag?

Yea so to make it work I guess you do need to run the manual process.

I just have updated RVM, you should try:

rvm get head && rvm reload
rvm reinstall 1.9.3 --force-autoconf --patch debug -j 3

@mpapis Worked like a charm, thank you sir!

There is a new version of ruby-debug which fixes 1.9.3, no recompilation needed: http://rubyforge.org/frs/?group_id=8883
