A little search turned up these versions.

./NVIDIA/CUDA-5.5/lib/libcudart.dylib
./VMD 1.9.1.app/Contents/vmd/libcudart.dylib
./MATLAB_R2013b.app/bin/maci64/libcudart.dylib
/local/cuda/lib/libcudart.dylib

I think the first it the one it should be finding.
I donít know why such a library is included in vmd, but I am going to assume its legitimate
Same for the Matlab one
I assume it may be the /local version that is creating the problem.

FYI,

which nvcc
/Developer/NVIDIA/CUDA-5.5/bin/nvcc

Hello,

I am trying to pin down why my version of VMD 1.91.1 built from source has
started seg faulting. (Note, i cannot run vmd -debug because gdb is no
longer included with Xcode on Mavericks as a command line tool, you can get
it from macports but it is now called ggdb )

I started with verifying if I download and run the VMD1.9.1 binary that it
still works. What I found is that this version does work, MacOS X OpenGL
(32-bit Intel x86) (Apple MacOS-X 10.5.x or later).

This version crashes, MacOS X OpenGL, CUDA (32-bit Intel x86) (Apple
MacOS-X 10.5.x or later with CUDA)

It cannot seem to interface with the cuda library correctly

 Reason: Incompatible library version: VMD requires version 1.1.0 or later,
but libcudart.dylib provides version 0.0.0

hi carolyn,

this looks like VMD picks up some old and incompatible version of the
cuda runtime library from somewhere.
