How to make Fuzzy Finder and Mac Vim 7.3

Hi all.

I am pretty sure that if you area fan of Fuzzy Finder for Vim and an user of Mac Vim you have to be very annoyed because of the errors from Fuzzy Finder when using the latest Mac Vim updated to the recent Vim 7.3.

This is the typical error you get when activating any Fuzzy finder mode:

E806: using Float as a String

Among others errors.

Well this problems comes because when starting Mac Vim from the Dock or Spotlight for some reason it doesn't pick up the correct locales.

More explanations in these links:

The most common solution is to launch MacVim from the Terminal.app using the mvim command, this way MacVim will inherit the locales from the Terminal which are correct.

But this is really annoying and I wanted to be able to launch MacVim from the Dock.

So I try setting the environment variables for my session according to the locales from the Terminal.app.

To do this first run the locales command:

pablo@cube ~ $ locale

LANG="es_ES.UTF-8"

LC_COLLATE="C"

LC_CTYPE="C"

LC_MESSAGES="C"

LC_MONETARY="C"

LC_NUMERIC="C"

LC_TIME="C"

LC_ALL=

Then I have use the Pref Pane app called RCEnvironment to add these variables to my session.

And voila! it works!

The idea is to setup the same variables from the locale command for your session.

Happy viming!

HDK in the Mac. Using hcustom with Leopard

Well, I have recently tried to compile some custom SOPs in my Mac.
No luck at the beggining so I begin to as in the Houdini Mailing list, Odforce, but no luck.
In my first try I got these errors:

Compile failed

I am using Mac OS X 10.5.X, Leopard. So asking to SESI seems I have some problems with the gcc version.
I have been using Xcode 3.0 which uses gcc 4.0.1, whereas Houdini is compiled against gcc 4.2.
So I installed Xode 3.1.3, which is the latest version for Leopard and includes gcc-4.2.
You can grab it from here:
http://connect.apple.com/cgi-bin/WebObjects/MemberSite.wo/wa/getSoftware?bundleID=20414
Now, how to use it, you can go to the dirty solution, removing cd gcc links in /usr/bin and make new ones pointing to gcc-4.2:

cd /usr/bin
rm cc gcc c++ g++
ln -s gcc-4.2 cc
ln -s gcc-4.2 gcc
ln -s c++-4.2 c++
ln -s g++-4.2 g++

Or the clean solution, don't touch the system just add some environment variables:

# Use GCC 4.2 rather tha GCC 4.0
export CC="/usr/bin/gcc-4.2"
export CPP="/usr/bin/cpp-4.2"
export CXX="/usr/bin/g++-4.2"
# Use GCC 4.2 for HDK
export HOUDINI_CC=$CXX

I put the text above in my ~/.bashrc
The first thre variables are for the usual GNU tools.
The last one is used by hcompile, the script called by hcustom to compile your DSO.
Now you can try hcustom and see your DSOs happily compiled.
Happy hacking!
