The -m64 seems to be a buried unaccessable option due to nvcc_flags variable within cmake-2.8.0-win32-x86/share/cmake-2.8/Modules/FindCUDA.cmake which generates my nbody_generated_bodysystemcuda.cu.obj.cmake file. If I try the wack-a-mole approach:<br>
<br>SET( nvcc_flags "" CACHE STRING "" FORCE )<br><br>a whole lota of nothing happens.<br><br>I forced this in the build by editing nbody_generated_bodysystemcuda.cu.obj.cmake and changing: <br><br>set(nvcc_flags "-m64")<br>
<br>to<br><br>set(nvcc_flags "")<br><br>and this removes it from the build line. This does not fix my problem, but it was curious how there was no way to force or change this option.<br><br>Brian<br><br><br>
