Re: [gmx-users] linking gromcs to efence
Hi Jochen, it should work by putting it in the LDFLAGS. Either you should then get an executable that says something like Electric Fence 2.2.0 at the very start of execution or it should not compile when the library is not found.

[gmx-users] Questions about Pull Code
Hello, I am a new Gromacs user, and I could really use some clarification about the pull code. I am interested in creating the PMF for Na+ and I- in the presence of THF. I saw a previous posting that the best way to go about creating the PMF is: 1) Generate a trajectory of configurations along the reaction coordinate. 2) Use the difference configurations as starting points for independent simulations in sampling window. 3) Use umbrella sampling to constrain in window. 4) Use g_wham to construct PMF This is how I am interpreting the instructions, but could you please let me know if I am correct in my assumptions? First I create a couple of unique starting configurations, with Na+ and I- separated by specific distances. Once that has been done, I take one such configuration and turn on the options under com_pulling (especially pull_geometry = umbrella) in the .mdp file. I let this run for some amount of time, and end up with a pullx.xvg and a pullf.xvg file. I do this with the other configurations as well. Once that has been done, I take all of these .xvg and .tpr files and create a .dat file, which can be used with g_wham to construct the PMF. I really appreciate the help. Nobody in my lab has done this before, and I am feeling pretty unsure of myself.

Certainly not without more useful information - GROMACS version, simulation system size, actual command line. Even then, the best guess is probably that you're running genbox on a machine for which it wasn't compiled, or for which some shared libraries have been updated in an incompatible way. Try recompiling GROMACS if so.
