Question

Following this writeup…

The compiled binary seems to work fine, but the installed binary fails (when running make install).

It seems to be failing on this step:

...
generating help tags
/usr/local/bin/vim -u NONE -esX -c "helptags ++t ." -c quit
dyld: Symbol not found: _environ
  Referenced from: /Users/neezer/.rvm/rubies/ruby-1.9.2-p0/lib/libruby.1.9.1.dylib
  Expected in: flat namespace
 in /Users/neezer/.rvm/rubies/ruby-1.9.2-p0/lib/libruby.1.9.1.dylib
make[2]: *** [vimtags] Trace/BPT trap
make[1]: [installrtbase] Error 2 (ignored)

I used this to configure:

./configure --prefix=/usr/local --enable-rubyinterp --enable-gui=no --disable-gpm

Like I said, I think it compiled correctly, because I can run ./src/vim after make just fine (no errors). But when I try to run the installed version after make install in /usr/local/bin/vim, I get this (mirrors above):

dyld: Symbol not found: _environ
  Referenced from: /Users/neezer/.rvm/rubies/ruby-1.9.2-p0/lib/libruby.1.9.1.dylib
  Expected in: flat namespace
 in /Users/neezer/.rvm/rubies/ruby-1.9.2-p0/lib/libruby.1.9.1.dylib
[1]    13175 trace trap  vim

Running which vim verifies that it is trying to load the new binary in /usr/local/bin/vim.

My current version of Ruby is ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.5.0] via RVM.

What’s happening here?

And no: I don’t want to just use MacVim instead…

Says right in the blog post:

you’ve probably fallen prey to a (currently) not very well documented issue: Vim 7.2 does not support the integration of Ruby 1.9.x on Snow Leopard.

There’s more information available in this ticket.

But in summary, you have to link against Ruby 1.8.7, which is the version that ships with Snow Leopard anyway.
