A quick search on google shows that building VIM against a modern ruby version on OS X isn’t trivial.
This is worth reading if you’re trying to build vim in this environment and have seen the following error:
dyld: Symbol not found: _environ Referenced from: /Users/bmatheny/.rvm/rubies/ruby-1.9.3-p194/lib/libruby.1.9.1.dylib Expected in: flat namespace in /Users/bmatheny/.rvm/rubies/ruby-1.9.3-p194/lib/libruby.1.9.1.dylib  54384 trace trap ./src/vim.stripped --version
After you’ve grabbed the source for VIM and unpacked it, configure VIM as follows:
1. Configure VIM
./configure --with-features=huge --enable-cscope --enable-rubyinterp=yes --enable-multibyte --enable-clipboard=yes
--enable-rubyinterp=yes is important.
2. Edit config.mk
src/auto/config.mk and change the
LDFLAGS line so it looks like:
LDFLAGS = -L. -arch x86_64 -L/Users/bmatheny/.rvm/rubies/ruby-1.9.3-p194/lib -L/usr/local/lib
This adds the rvm library path for the version of ruby you want to link against to the link path.
3. Fix the stripped version
When you run
make install, the vim executable will get stripped (symbols will be removed). Just copy
src/vim in place of
/usr/local/bin/vim (or wherever you have it installed). The vim binary at
src/vim still has a a fat symbol table.
