OS X Compilation Failure

[zorgiepoo]

On Xcode 5.1 (clang-503.0.38) and OS X 10.9, executing "sudo gem install jekyll" gives this error:

Looks like a problem with Xcode & clang 5.1. Please ask the fast-stemmer team to help out (it's with regard to their gem)

Just tried a clean install, seems to work.

@tompave it works fine with Ruby 2.1.1, but fails with the system-default Ruby (which is 2.0.something)

[nghuuphuoc]

Thanks @tompave
It worked for me too 👍

[thepatrick]

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll

Works around this issue for me

[ghost]

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll

This works for me too!

[manmadewind]

@thepatrick, Thank you! That worked for me!

[liuyu121]

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll

Yeah, great job. So Thanks. @thepatrick

But anyone can explain it ?

[liuyu121]

And may be must use the SUDO do it .

I think it is caused by defaults that mkmf brings in (as I've had other occurrences of the same error), and probably there is too little motivation to "fix" it when all people will want to do is to use Ruby 2.1 and higher.

[linus-young]

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll

works for me too!
ps: I'm using OS X 10.9.2 & ruby 2.0.0p247 & clang 5.1

[michaeljdeeb]

When using the workaround @linus-young, were you able to successfully run jekyll serve --watch on a folder? I ran into issues where it was trying to execute from within the iOS Simulator directory.

Using Ruby 2.1 via RVM solved my issue.

[linus-young]

@michaeljdeeb I edit a file in _site folder, and in terminal it displayed Regenerating : 1 files .... done , then in browser it worked.

For those purists, that, for whatever their masochistic reasons (myself included), wish not to employ sudo, rbenv, homebrew, or otherwise, and wish to remain user-locally, within their native OSX environment, the following works, for now, until fast stemmer is rectified, on a clean Mavericks installation:

• ensure ~/bin exists; e.g. mkdir ~/bin

export PATH=$PATH:~/bin ; ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll --no-document --user-install --verbose --bindir ~/bin

• For availability and persistence of binaries in ~/bin, consider permanently adding ~/bin to your $path via however you normally do that; usually ~/bash_profile, etc.

$ cd ~

$ which jekyll
/Users/jaybe-jekyll/bin/jekyll

$ jekyll new whee
New jekyll site installed in /Users/jaybe-jekyll/whee.

[kevinpapst]

Thanks @jaybe-jekyll, your solution worked for me.

[jaybe-jekyll]

@kevinpapst, you are welcome; and thank you for reporting and sharing your success.

As an added bonus and effort in proactivity, safety, and stability, please also consider the following:

Upgrading/Updating Jekyll

• Same as installation approach but with slight gem command line modification: update
  • ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem update jekyll --no-document --user-install --verbose --bindir ~/bin
    • (difference: s/install/update/)

Generally-major Gotcha'

• It is generally unwise and dangerous to ever contemplate doing the following on a standard OSX installation, and generally- also within Linux, when behaving as a purist with Ruby (or Python) outside of using an environment manager such as rbenv, rvm, etc.:
  • sudo gem update --system <-- masochism
  • sudo gem update <-- masochism
• Doing that on an OSX/Linux system will introduce pain and entropy into a stable and managed system, purposely interjecting and overwriting the system' interests.

An (likely silly) analogy is documenting a recipe by hand on a recipe card. Instead of getting your own card, and writing it down- just for you- and keeping it in your own box, you go out and replace everyones recipe card with your recipe and force everyone and everything to use only your recipe. Eventually, someone is going to want their gumbo recipe back, and they'll throw a fit when they don't get what they expected.

Ensuring Understanding of User-space Approach

• The purist approach of installing gems within user-space is not new or revolutionary.
• Ruby environment managers such as rbenv, rvm, etc. perform similar functions, albeit more advanced and flexible, and manageable, generally for developers and tinkerers.
  • For the basic, average, non-developing user, that simply wishes to have, run, use, and update a gem (jekyll), and continue using the system' ruby, this approach is effective.

We are basically just telling gem, ...

Please install jekyll, via gem, but do it within my user space (--user-install) ...
... so the backend code and dependencies get installed to my home directory (~) in, i.e. ~/.gem/ruby/2.0.0/..., ...
... and the binaries that get run, such as jekyll, redcarpet, etc. are installed in my binary directory (--bindir ~/bin) within my home directory, instead of the system', at ~/bin/jekyll, ~/bin/redcarpet, ..., etc.

So, in General... choices...

• $ gem install jekyll --user-install --bindir ~/bin, or...
• $ gem install jekyll --user-install --bindir ~/bin --no-document, or...
• $ gem install jekyll --user-install --bindir ~/bin --no-document --verbose, or...
• $ gem update jekyll --user-install --bindir ~/bin ... ... etc.

Ruby 2.1 solves it!!!!!!!!!!!!thanks a lot

[shaoweiD]

thanks @tompave

[fengs]

Upgrading ruby to 2.1.5 solves this. Thanks.
