So here it is this year I was Optimus Prime, sorry for the quality of my photo auto focus was left off, hopefully someone gets me a crisper copy. I’ve also included meg’s very nice Samurai PIzza Cats costume:

Optimus Prime Costume

Who you gonna call when you need some pepperoni!

Total time for the costumes was about 6 days, trophies were won.

I am currently working on a small MPI project, and I had one hell of a time getting MPI up and running, specifically the MPICC (compiler) to work in xCode.

So here it is if you were wondering how to get it to work:

Put the following into a file called MPICC.pbcompspec

Note: ExecPath should be set to your mpicc path, find this by typing which mpicc in terminal. BasedOn should be set to whatever the system GCC is (4.2 for snow leopard).

Save this file to the following directory: /Developer/Library/Xcode/Specifications/, if the directory does not exist, create it, restart xCode.

Finally in your project, open the build targets and select the one you want to build with MPICC, get info on it, and add a custom rule for c source, MPICC should be in the list somewhere, if it is not then you messed up somewhere above.

Setting a custom C xCode target rule

The file: mpicc.pbcompspec
