==Building PBRT on Linux (the 'myth' machines in Sweet Hall)==

The public release of PBRT 1.02 available on [http://www.pbrt.org www.pbrt.org] requires modification to build on Stanford's 'myth' machines.  We have placed a myth-specific tar file online at {{{/afs/ir/class/cs348b/pbrt/pbrt1.02.cs348b.tar.gz}}}.  This archive contains two subdirectories:
 * {{{/pbrt}}} - which contains the PBRT 1.02 source tree with modifications made to its makefiles
 * {{{/cs348b_extras}}} - which contains a build of OpenEXR and libtiff that are required to properly build PBRT on myth.

After unzipping this archive to {{{%%MY_LOCAL_DIR%%}}} in your home directory, you will need to add the following directories to your environment's library search path.
 * {{{%%FULL_PATH_TO_MY_LOCAL_DIR%%/pbrt/bin}}}
 * {{{%%FULL_PATH_TO_MY_LOCAL_DIR%%/cs348b_extras/lib}}}

For example, assume I unzipped the archive to {{{/afs/ir/stanford/users/k/a/kayvonf/src}}}.  Then in csh I'd set my LD_LIBRARY_PATH to:

{{{setenv LD_LIBRARY_PATH /afs/ir/stanford/users/k/a/kayvonf/src/pbrt/bin:/afs/ir/stanford/users/k/a/kayvonf/src/cs348b_extras/lib}}}

So the entire process to compile PBRT on a myth machine is:

 1. extract {{{/afs/ir/class/cs348b/pbrt/pbrt1.02.cs348b.tar.gz}}} into your local AFS space.
 
 2. set the appropriate LD_LIBRARY_PATH (probably a good idea to add this to your .login)
 
 3. build pbrt by typing 'make' from the /pbrt directory
 
 4. build the tools by typing 'make' from the /pbrt/tools directory
