Hi All,

I've been trying to build AFNI on a Yosemite + MacPorts machine. I started with a functioning 10.8 Makefile, and on the first pass through, I got this error when trying to build the main AFNI binary:



/bin/rm -f afni
/usr/bin/gcc -O2 -m64 -DDARWIN -Wcomment -Wformat -DUSE_TRACING -DHAVE_XDBE -DDONT_USE_MCW_MALLOC -o afni afni.o afni_func.o afni_widg.o afni_warp.o afni_fimmer.o afni_slice_short.o afni_slice_float.o afni_filer.o afni_slice_byte.o afni_slice_complex.o afni_pcor.o afni_pcor_float.o afni_transforms.o pbar.o afni_graph.o afni_plugin.o afni_cluster.o parser.o parser_int.o afni_plugout.o afni_fimfunc.o afni_setup.o afni_receive.o mcw_graf.o afni_splash.o afni_pplug_env.o afni_pplug_2dfunc.o afni_friends.o afni_ttren.o afni_pplug_1dfunc.o afni_driver.o afni_niml.o afni_sumafunc.o afni_slice_rgbyte.o afni_version.o afni_lock.o afni_vol2surf.o afni_pplug_instacorr.o afni_pplug_instacalc.o -m64 -dynamic -L. -L/opt/local/lib -L/usr/lib -L/usr/X11R6/lib -L/opt/local/lib -Wl,-x -Wl,-multiply_defined -Wl,warning -Wl,-bind_at_load -lmrix -lcoxplot -lmri -lvolpack libXmHTML.a libjpeg.a -lmri -lf2c -lXm -ljpeg -lXt -lXft -lfontconfig -lpng -liconv -lXmu -lXp -lXpm -lXext -lX11 -lz -lexpat -lm -lc -lm -lc

I tracked the functions down, and mri_rotate is in mri_warp.c, which is compiled into libmri. Is this a linking order issue with clang?

Thanks all!
