Tony,
the powerpc is a big-endian processor, so make sure the BYTEORDER gets defined as 4321 by configure (see a Makefile). see dcm.c for code that depends on endianness and make sure the big-endian code gets compiled. i dont think the configure.in script is smart enough to setup the endian order for linux powerpc (it did for powerpc on the mac).

Hi, Does anyone have any advice for compiling freesurfer on Linux powerPC architectures?
I've managed to compile a 64-bit version of freesurfer on Linux PowerPC, and I'd be happy to post the documentation for the compile process I used - if I could be sure it would build usable binaries :-( So far, the compiled binaries run in to some fairly basic problems with opening DICOM files. Here's an example using mri_probedicom with the debugging cranked up, trying to open a file that opens fine using the precompiled x86 mri_probedicom binary:
# mri_probedicom --i /tmp/s003/E16002S003I00001.dcm
