Is this issue ongoing?
I'm just in trouble with the issue.

[colszowka]

Yes, I am having this issue with 1.6.6 and against 2.1.2 as well.

[tgautier]

Same here. Issue with 1.6.6 with ruby 2.1.2 on OSX 10.9.2

[caarlos0]

same here!

[sjfxb]

👍 and there is a PR for that issue.

[PikachuEXE]

Support for Ruby 2.1.2p95 would be groovy.

Hey folks, please refrain from posting spammy +1s and pinging everyone subscribed to this thread. I think the point that this is broken on Ruby 2.1.2 has been made and proved, and either someone with the time and knowledge will submit a fix PR or you tackle this and do the same. I don't think putting +1 comments on this thread will speed things up. Thanks!

[tgautier]

There's already a PR #126

[lucascaton]

@cldwalker @astashov @mark-moseley @nobu,
Hey guys, any news from this one?
Thanks.

[jpstokes]

I've having the same issue.

[gmmeyer]

I am having this problem on linux as well, it's not confined to mac.

For ruby 2.X debugging, I now recommend byebug or debugger2. I've updated the README to indicate this. Reasons for this:

• debugger has never had full ruby 2.x support. An open call was made to the community more than a year ago but no one stepped up. See officially support ruby 2.X #47.
• The rails community has thrown its weight behind byebug for 2.x debugging.

In a week, I will be closing all ruby2 issues including this one. I will hold off on closing them if someone takes up working on 2.X support. I'm happy to provide github and gem push access as needed.
Is @astashov, @nobu, @sunaku, @windwiny or anyone else interested in adding 2.X support for debugger?

This requires doing the following with ko1's pull request, #69:

• Resolve merge conflicts. A fair amount has landed on master since the pull request
• Disable tests and features that have not been ported to 2.x e.g. post-mortem and threading. Disabling should only be done for 2.x rubies.
• Ensure all tests pass on 2.X rubies
• No longer depend on ruby internals (see officially support ruby 2.X #47 for some discussion). This means there should be no dependence on https://github.com/cldwalker/debugger-ruby_core_source. This should be resolved by the pull request but is important to state nontheless.

[cldwalker]

I am also looking for 1.9.X maintainers if anyone is interested

[jasonzhao6]

What are the pros and cons of byebug vs debugger2?

[nathany]

Our reason for using debugger (with Ruby 2.1) is that pry-debugger currently depends on it. /cc @nixme

[patrickespake]

+1 for Ruby 2.1.3

[ghost]

I believe we are supposed to use byebug for ruby 2+.

[albe-rosado]

it is fixed or still ongoing? every time i try to install pry-byebug or byebug or debugger or debugger2 i get this:

ERROR: Failed to build gem native extension.
