I found that I didnt have usrincludeiconv.h due to some kind of problem with OS upgrades or restores from backups.

If you dont have that header file and usrliblibconv.dylib after running xcode-select then you most likely need to drag Xcode from the Application folder to the trash and reinstall and then manually download the Command Line Tools for Xcode from and install that.

You dont need this.

And clang will actually pick up usrlocalincludeiconv.h over usrincludeiconv.h and will define iconvopen to libiconvopen but then link against usrliblibiconv.dylib which does not have libiconvopen which is what causes the mkmf failures to find libiconv.

What you need to do is remove the linking in of iconv.h so that nokogiri will not find it.

Most of them attempt to use libiconv out of homebrew which is entirely unnecessary.

The answers that brew link libiconv are actually causing the problem where clang becomes confused and tries to read a homebrew header file and link against the system libraries.

The answers which suggest --use-system-libraries are poor because nokogiri needs to be linked against its bundled libxml2 and libxslt libraries because other versions of those libraries are incompatible with it.

The answers which want you to compile from sources are just hopelessly overly complicated.

Unfortunately the Installing Nokogiri doesnt cover Iconv issues.

If you already have it installed, be sure to grab the latest formulae by updating like so.

Then I finally found the iconv documentation and it saved my day.

The article explains it better than I can so read the above link for specific instructions.

Every time someone depends on a different version I have to figure out how to build it.

In my case when I hit this it was that Nokogiri specifically adds optlocallib to the library search path and GNU Backgammon had installed an incompatible libiconv there.

Now I am still facing problems though, because when I start up gollum, Python crashes.

OSX comes with libiconv in newer versions, but the defaults install script seems to have a problem.

See the Nokogiri install instructions under the Homebrew 0.9 section on the Nokogiri install page.
