Dear All,
When I start vmd 1.9.2 (compiled from source) with these options:
LINUXAMD64 OPENGL FLTK TK CUDA VRPN TCL PTHREADS
the following information are shown in the terminal window

Info) Multithreading available, 8 CPUs detected.
Info) Free system memory: 31007MB (96%)
Info) Creating CUDA device pool and initializing hardware...
Info) Detected 1 available CUDA accelerator:
Info) [0] Quadro K6000 15 SM_3.5 @ 0.90 GHz, 11GB RAM, KTO, AE2, ZCP
Info) OpenGL renderer: Quadro K6000/PCIe/SSE2
Info) Features: STENCIL MSAA(4) MDE CVA MTX NPOT PP PS GLSL(OVFGS)
Info) Full GLSL rendering mode is available.
Info) Textures: 2-D (16384x16384), 3-D (4096x4096x4096), Multitexture (4)

I loaded a .xyz file but
when I go to the menu --> Graphics --> Representations --> Drawing Method
= QuickSurf
it crash with the following error message

vmd > QuickSurf: R*1.0, I=0.5, H=1.0 Pad: 5.4 minR: 1.5 maxR: 1.5)
  GridSZ: ( 19 19 19) BBox: (-5.4 -5.4 -5.4)->(12.6 12.6 12.6)
Segmentation fault (core dumped).

When I use vmd installed by using binaries (LINUX_64 OpenGL, CUDA (Linux
(RHEL 4.6 and later) 64-bit Intel/AMD x86_64 w/ SSE, with CUDA))
it works fine and does not crash. Here is the console output

vmd > Info) VMD for LINUXAMD64, version 1.9.2 (December 29, 2014)

I want to use VRPN and have to use vmd which is compiled from source.
Can anyone please help to figure it out what's problem?
Maybe there is a simple solution to use the vmd binaries and get VRPN
working without compilation.

Br,
