183. Compiling OpenMM 4.1 on debian testing

OpenMM 4.0 is still somewhat of a traumatic memory. However, having gotten a question about the compilation of v4.1 I can't really resist giving the new version a go.

Having said that, I never ended up using the GPU-enabled gromacs for which I built openmm, so it was all an enormous waste of time -- for those of you thinking about GPU/Gromacs know this:
* not all graphics cards are supported or worth supporting
* there's no speed-up for explicit solvent molecules, and what else would you use gromacs or MD for?
* consumer-grade graphics cards get very hot

I make no attempt at ferreting out what packages are needed other than what I'm explicitly prompted for. Look at http://verahill.blogspot.com.au/2012/01/debian-testing-64-wheezy_20.html for an indication of what you might need.

Also, I already have openmm 4.0 installed, so e.g. paths and other things defined in the post above are still active.


Start here
Register with simtk.org and download the source file.
sudo apt-get install cmake-curses-gui libgccxml-dev gccxml nvidia-cuda-toolkit
unzip -x OpenMM4.1-Source.zipe
mkdir openmm_build
cd openmm_build/
ccmake -i ../OpenMM4.1-Source/

It'll say Empty Cache. Hit c which will populate the list.

I think we can ignore the EMU libs since they do device emulation. I never figured out what the CUT program was and it's not mentioned in the manual from what I can see.


These are the settings I chose -- I had problems before setting the OPENCL parts (in red) to off.

Make your changes and hit c again, then hit g which brings you back to the terminal.



make -d|tee make.log
