PBRT and Mac OS X 10.4.10

For a computer graphics class, I needed to build PBRT. Being a Mac guy, I decided to build it for Mac OS X. In addition, I wanted to make sure I was using the latest version of at least PBRT (it's at 1.0.3 as of this writing). I also wanted to use Fink as much as possible for any dependencies.

Getting the PBRT source code

To do this, you will at least need to grab the source code for v1.0.3 from PBRT's downloads page. If you want to try and of the sample scenes, however, you will need to grab them from the CD that came with the book. After unpacking it, I moved the new folder to ~/pbrt. If you want it somewhere else, make sure to change the PBRT_SEARCHPATH environmental variable in the next step accordingly.

Setting the environmental variables

In Mac OS X, I believe that if a .profile file exists in your user folder, any .bashrc file is ignored. It could also be that .bashrc is just plain ignored. In any case, Bash in Mac OS X likes using .profile, so putting this at the top of my file worked.

export PBRT_SEARCHPATH=$HOME/pbrt/bin
export PATH=${PATH}:/usr/local/bin:$HOME/bin:$PBRT_SEARCHPATH

If you have a Terminal window open, type exit and open a new window. This will ensure that your Terminal has these changes.

Getting the necessary Fink packages

I should point out from the start that I use unstable with Fink. OpenEXR is available in both stable and unstable, but we are talking a difference of version 1.2.2 and 1.4.0 as of right now. You can install the necessary packages using the command

fink install openexr ccache

in the Terminal. There is a good possibility other packages are needed. If something comes up, drop a comment and I will update this as necessary.

Examining GCC

Another goal when I started this was to use the latest version of gcc as provided by Apple (you could also try the latest version of gcc as provided by Fink unstable, if you would like). On my computer, typing gcc --version provides

powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc. build 5367)
Copyright (C) 2005 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

This will do fine--nothing special needs to be done.

Changing the Makefile

I am assuming that you have the default installation location of /sw for Fink (and if you don't, take it from someone who fought it for close to four years--make a symbolic link to /sw at least. It's not worth the pain.) The only lines necessary to change are the following three:

EXRINCLUDE=-I/usr/local/include/OpenEXR
EXRLIBDIR=-L/usr/local/lib
EXRLIBS=$(EXRLIBDIR) -Bstatic -lIex -lIlmImf -lImath -lIex -lHalf -Bdynamic -lz

should become

EXRINCLUDE=-I/sw/include/OpenEXR
EXRLIBDIR=-L/sw/lib
EXRLIBS=$(EXRLIBDIR) -Bstatic -lIex -lIlmImf -lImath -lIex -lHalf -lIlmThread -Bdynamic -lz

For reasons which I are probably not very interesting, they forgot to include the IlmThread library. The last line there adds it.

Finishing the job

At this point, all there is to do is to type make.

Xcode 3 language specification changes

So much has changed in Leopard that I am not surprised I cannot find anything about this yet. Basically, the plugin interface for Xcode 3 has severely changed. In particular, over the past few days I have been trying to make a *.pblangspec file for the programming language used by my group for software verification purposes (who, it ought to be noted, I do not speak for on this website). It turns out, that’s not what I really wanted to do. I am still trying to figure out what all has changed, but here are a few key differences: The file format is totally different. This is somewhat superficially noted by the fact that the file’s extension should now be xclangspec as opposed to pblangspec . For instance, I am using Resolve.xclangspec . The file format is totally different. I’m mentioning it twice, mainly to point out that there are no guides out there for it yet. It seems to make sense, if you realize that Xcode is now doing a lot more than just keyword matching and using regular

Redux on iPhone and iPod Touch, 802.1X and LEAP

Strangely, this from October seems to be getting a lot (well, for me) traffic lately. That’s not really interesting enough to post about, but it seemed that it did make the following note more… well, noteworthy. While I don’t have either an iPhone or an iPod Touch, I do at least know someone who has an iPod Touch and could check this for me. So: It still doesn’t work in version 1.1.3. Although I haven’t seen anything about the iPhone, I would be heavily surprised if it weren’t the same deal there. Technorati Tags: iPhone , iPod

iPhone and iPod Touch, 802.1X and LEAP

This is more a note for people who were wondering like myself: the current OS X that comes with the iPod Touch and iPhone cannot handle either 802.1X or LEAP (before anyone tells me it handles 802.11x just fine, please remember that 802.1X and LEAP are specific forms of encrypting a wireless connection, not types of wireless connections. 802.1 1 x is instead a generic term used for the varying speeds of wireless, i.e. 802.11a, 802.11b, 802.11g, 802.11n, ….) This is really too bad, as both are have been built in to Mac OS X since at least version 10.3, and also both are the main ways I can get wireless at OSU . I have every intent on finding out if this gets fixed with subsequent OS updates. Incidentally, a big reason I am posting this is due to some Apple Store employees erroneously telling me it should work on the iPhone and iPod Touch, since it is built in to Mac OS X, which shares a lot of common code with the OS X on both devices (as far as anyone seems to know). I don’t fault th
