log4cpp universal dylib on OS X

Configure and make using GCC 4.0 for x86_64 i386 and ppc against the 10.5 sdk then modify the library using install_name_tool.

$ ./configure --disable-dependency-tracking
$ make CC="gcc-4.0 -arch x86_64 -arch i386 -arch ppc7400" CXX="g++ -arch x86_64 -arch i386 -arch ppc7400 -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5"

$ cd src/.libs/
$ rm liblog4cpp.dylib
$ cp liblog4cpp.4.0.6.dylib liblog4cpp.dylib
$ install_name_tool -id @executable_path/liblog4cpp.dylib liblog4cpp.dylib

You may or may not need to modify the library after running make, it depends how the library is bundled with your application.

Recommendation: z

z is an awesome bash script that stores a list of your frequently used directories.

Instead of typing:

cd ~/Work/ProjectsFolder/ProjectA/Something/Src/

You can type:

z ProjectA

It’s utterly brilliant, check it out on GitHub: http://github.com/rupa/z/

Thanks to Ben Tappin for the tip.

Project specific .vimrc / How to modify the python path when working in Vim

Thu, 16 Dec 2010 11:50:15 -0500

In Vim I often find the need to add my python project to the PYTHONPATH so I can run external tools, code completion etc.

Try opening a Django project in Vim and importing a model:

:cd ~/Your/Project/Dir
:!python
>>> from yoursite.yourapp import models

You’ll get the following error:

ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.

Which makes sense, your project source isn’t on the python path. Here’s my solution to applying project specific vim settings / updating the python path:

Add the following line to your vimrc:

" Read .vimproj in the working directory
map  P :source ./.vimproj

Then create a file in your project root called .vimproj with the follwing contents:

" Mysite Specific Vimrc

let $django_dir = getcwd()."/"
let $lib_dir = getcwd()."/libs"
let $site_packages_dir = "/Library/Python/2.6/site-packages/"

if !exists("g:python_dirs_loaded")
let g:python_dirs_loaded = 1
let $PYTHONPATH = $django_dir.":".$lib_dir.":".$site_packages_dir
set path=$django_dir
set path+=$lib_dir
set path+=$site_packages_dir
endif

let $DJANGO_SETTINGS_MODULE = "settings"

echo "Mysite settings loaded"

When I open a project bookmark in NerdTree, I type cd to change the working directory to the project root, then hit ,P to load the project specific settings.

Inconsolata-dz is an excellent programming font, based on Inconsolata, that’s been modified to use straight single and double quotes.
